Cover Photograph:

This aerial photograph of the northwest portion of Bear Lake was taken in the fall of 2004 justa few months prior to the lowest level of the lake since 1935. Imposed on the photo is ahydrograph of lake elevations from October 1, 2002 until September 30, 2004. The photographand the hydrograph were suggested to the Commission by Connely Baldwin, an official withPacifiCorp. The orthorectified photograph is from the National Agricultural Imagery Program(NAIP) which is administered by the U.S. Department of Agriculture, Farm Service Agency,Aerial Photography Field Office.

The period of this biennial report was one of limited precipitation and snow pack and so storagewater was heavily drawn from the storage reservoir portion of Bear Lake to supply water todownstream irrigators. The extent of the drought and the use of this important reservoir arediscussed in this report.

The top of the photograph is at the north. The light brown area is exposed beach. Near the topof the photo the beach is broken by four channels. Going clockwise or from left to right, the firstchannel is a distributary, or the south branch of St. Charles Creek (also called "Little St. CharlesCreek"). It enters Bear Lake right at the "2003" on the cover. The second stream is the northdistributary of St. Charles Creek (also called "Big St. Charles Creek") which at the time of thephoto entered the lake near the "v" in the word River. Next, to the right, is the channel thatallows water to flow north to PacifiCorp's Lifton pumps. The pumps are near the top of the letter"O" in the word "report." The last channel to the right is the channel where releases from thegates on Mud Lake are allowed by PacifiCorp to flow water from the Bear River and Mud Lakeinto Bear Lake. The green waters of Mud Lake can be seen in the very top right of the photo. Afew streets in the Idaho community of St. Charles can be seen at the left of the photo near thetop.

THIRTEENTH BIENNIAL REPORTBEAR RIVER COMMISSION

OVERVIEW

SYNOPSIS

This biennial period saw the continuation of a drought cycle. The two biennial yearsboth had well below normal precipitation which followed the three prior years which were alsovery dry years . After five straight wetter than normal years in the late 1990's, the first fiveyears of this new century, including the two associated within this biennial period, wereextremely dry. Storage supplies were depleted during this dry period and new storage each yearwas very limited. Even with storage usage restrictions in place, Bear Lake dropped more thanfour and a half feet in elevation over the biennial period and Woodruff Narrows Reservoir wasnot able to fill either year. In the Upper Division, a water emergency was declared for portionsof each year and interstate regulation was made. The Central Division was found to be in awater emergency during the entire irrigation season of both years and interstate regulation wasimposed. In the Lower Division, water supplies were also very tight. In 2001, for the first timeever, storage water deliveries were limited by the terms of the Bear Lake Settlement Agreement.The Settlement Agreement also limited the allocation of Bear Lake storage water in both yearsof this biennial period. During the biennial period, equitable distribution of waters wasmaintained due to the comity of the states and the provisions of the Compact.

This biennial report is divided into three chapters. This first chapter, the OverviewChapter, provides a background of the Compact and the Commission and its general activities.The second and third chapters provide specific water supply and streamflow distributioninformation for the 2003 and 2004 water years, respectively.

BACKGROUND

The Bear River Compact determines the rights and obligations of the signatory statesof Idaho, Utah and Wyoming with respect to the waters of the Bear River. Federal consent tothe Compact was given by the Congress and signed by President Eisenhower on March 17,1958. The Bear River Commission was created by the Compact and has been organized as aninterstate agency to administer the Compact.

The Bear River Compact was amended in accordance with Article XIII of the OriginalCompact (Article XIV, Amended Compact) following several years of study and review ofcompact provisions. Principal amendments and other changes are discussed elsewhere in thisreport. Amendments to the Compact were agreed to by representatives of the compacting stateson December 22, 1978 and State Amending Legislation was approved in each state in the springof 1979. Congressional consent was given by the 96th Congress by Public Law 96-189 andsigned into law by President Carter on February 8, 1980.

O-2

Article III.D.2 of the Compact was amended to provide that the Bear River Commissioncompile a biennial report rather than an annual report as required in the original Compact.Annual reports were compiled in each of the 21 years (1958-78) and were transmitted to thePresident of the United States and to the Governors of the signatory states. This is theThirteenth Biennial Report covering the 2003 and 2004 water years (October 1, 2002, toSeptember 30, 2004).

River operation under the Bear River Compact and activities of the Bear RiverCommission during the 2003 and 2004 water years are summarized in this report, by year, inthe two chapters which follow. This biennial report is organized so that specific informationfor each water year is reported in separate chapters. Selected streamflow records are given inthe chapters discussing each water year.

COMMISSION ORGANIZATION & MEMBERS

Ten commissioners, three representing each state and one representing the United States,constitute the Bear River Commission. The Federal representative serves as chairpersonwithout a vote, while each of the other nine Commissioners have one vote. Figure O.1 lists theBear River Commission membership as of October 1, 2002.

There were two changes in the Commission membership during the biennial period. OnMay 8, 2003 Governor Dave Freudenthal designated Sam Lowham and Gordon Thornock toreplace James Crompton and John Teichert on the Commission. Former Commissioner CalvinW. Funk passed away in Richmond, Utah in November of 2002. Funk served as aCommissioner from 1987 until 1997.

The Commission amended its bylaws on April 16, 1990. The amendments allowed forthe creation of three standing committees of the Commission: the Management Committee, theOperations Committee, and the Records Committee. On November 18, 1997, the Commissionagain amended its bylaws and changed the name of the Records Committee to the Records &Public Involvement Committee. A Water Quality Committee was also created on November18, 1997. These standing committees have duties as assigned to them by the Commission.Each state is allowed to designate its representatives to the committees, and in all committeesvotes are taken by state, with each state having one vote. These four committees met from timeto time on an as-needed basis throughout this biennium.

The bylaws also provide for the creation of special committees which may be assignedtasks as deemed necessary. The Technical Advisory Committee (TAC) has been created by theCommission and serves the Commission as a whole (and each of the standing committees) ontechnical matters. The TAC is composed of state water agency personnel and is chaired by theEngineer-Manager of the Commission.

MEETINGS

Four Regular or Annual Commission meetings and one special Commission meetingwere held during the biennium. The dates of the meetings are as follows:

October 21, 2002 Special Meeting Conference CallNovember 19, 2002 Regular Meeting Salt Lake City, Utah

April 15, 2003 Annual Meeting Salt Lake City, Utah November 18, 2003 Regular Meeting Salt Lake City, Utah

April 20, 2004 Annual Meeting Salt Lake City, Utah

The two Regular and two Annual meetings of the Commission were held at the UtahDepartment of Natural Resources Building in Salt Lake City, Utah. A special meeting of theCommission was held via a conference call on October 21, 2002 to address the issue ofsubmitting a grant request to the U.S. Environmental Protection Agency in regard to theWatershed Initiative. The Commission approved the submittal of a grant request. At the annualmeetings held in April, elections were held and fiscal matters were addressed. A fiscal reportfor the biennial period, prepared by the Treasurer, has been made a part of this chapter. Formalminutes for all five of the Commission meetings have been approved and can be reviewed atthe Commission offices for details concerning the Commission's actions.

COMMISSION ACTION & ACTIVITIES

This section is to provide a brief accounting of significant actions or activities of theCommission during the biennial period separate and apart from specific streamflowmeasurement and distribution which are discussed elsewhere in this report. Greater detailsrelative to specific actions or activities of the Commission are contained within theCommission’s approved meeting minutes.

The first meeting during the biennial period was the one-hundredth meeting of theCommission and it was a special meeting that allowed the Commission to conduct business viaa conference call. It was held on October 21, 2002. During the call, the Commission approvedthe submission of a “Watershed Initiative” grant request to the EPA. The Water QualityCommittee had advanced this request to the Commission.

The second meeting of the biennial period was held on November 19, 2002. DeeHansen, who had been appointed by President Bush to be the Federal member of theCommission, was introduced. Hansen then chaired this meeting and a vote of appreciation wasgiven to the out-going Chair, Denice Wheeler. At this Commission meeting there was a briefcelebration held noting the one-hundredth meeting of the Commission.

On April 15, 2003, the Commission held its annual meeting and conducted annualbusiness by electing John Teichert to serve as Vice Chair of the Commission and LarryAnderson to continue to serve as Secretary-Treasurer. It was reported that the elevation inreservoirs were low and that the snow pack was well below normal. Bear Lake elevations,being below 5911, will limit upstream storage as provided for by the Compact. At theCommission meeting, an addition to the Interim Procedures for Lower Division Water Deliverywas approved. It concerned the depletion to be recognized by the Commission to the Bear

O-5

River by ground water use in the Lower Division. The Commission noted that this proposedamendment needs to be made the subject of a public meeting.

A regular meeting of the Commission was held on November 18, 2003 and Wyomingintroduced two new Commission members; Sam Lowham and Gordon Thornock. Resolutionsof appreciation were approved for outgoing Commissioners James Crompton and John Teichert.Commissioner Thornock was then elected Vice Chair of the Commission. At this meeting, theCommission again addressed and approved changes to the Lower Basin Procedures andinstructed the Engineer-Manager to arrange for public hearings. It was noted that because ofa severe dry year Bear Lake storage was nearly been depleted and the lake dropped to about anelevation of 5904 feet.

The last Commission meeting during the biennial period was held on April 20, 2004 asan annual meeting. Noting that public hearings had been held, the Commission formallyamended the Lower Division Procedures. The Commission received reports concerning lowBear Lake and other reservoir levels, below average snow pack and very pessimistic forecastsfor the upcoming irrigation season.

FINANCIAL REPORT

The fiscal year of the Commission begins on July 1 of a given year and ends on June 30of the following year. D. Larry Anderson served as Secretary-Treasurer of the Commissionthroughout the biennium. The expenditures for the period are shown in Figure O.2 and werepresented to the Commission by the Treasurer.

The Commission records were audited by an independent auditor. The audit of accountsand records, including a statement of budget revenue and disbursements for the bienniumending June 30, 2004, is a part of the formally accepted Commission minutes.

Expenses incurred by the Bear River Commission are paid equally by the signatorystates. Compensation and expenses of the federal representative, each commissioner, and eachadviser are paid by the government which they represent.

THE BEAR RIVER

The Bear River drains an area of 6,900 square miles in southwestern Wyoming, northernUtah, and southeastern Idaho. Its headwaters are but 90 miles from its mouth, yet it meanders500 miles in a circuitous course in reaching the Great Salt Lake. In its travels, it makes five stateline crossings in three states. The map found on page ii shows the major features of the BearRiver system.

The Bear River is not only the largest tributary to the Great Salt Lake, but is the largeststream in the North American Continent that does not flow to an ocean. Prior to settlement andirrigation development, the annual discharge of the river into the Great Salt Lake averaged anestimated 1,750,000 acre-feet. Settlement of lands adjacent to the Bear River began in about1860 and power development began in 1907. In 1911, Bear Lake was converted into a storagereservoir by constructing inlet and outlet canals connecting the lake and the river.

Approximately 500 irrigation organizations own and operate separate irrigation systemsin the Basin, supplying irrigation water for half a million acres of land. Six hydroelectric plantsare in operation on the main stem of the Bear River.

In addition, numerous municipalities, communities, individual families, a variety ofindustrial and miscellaneous users, and waterfowl refuges withdraw water from the Bear River,its tributaries and its tributary ground water. Today, on an average, nearly a million acre-feetof water annually still flow into the Great Salt Lake from the Bear River.

BEAR RIVER COMPACT

The Bear River Compact is a document voluntarily adopted by the states whichestablishes the rights and obligations of Idaho, Utah, and Wyoming with respect to the watersof the Bear River. The Compact became effective on March 17, 1958.

The main purposes of the Compact are outlined in paragraph A of Article I of theCompact, which states:

The major purposes of this Compact are to remove the causes of present andfuture controversy over the distribution and use of the waters of the Bear River, toprovide for efficient use of water for multiple purposes, to permit additional developmentof the water resources of Bear River, and to promote interstate comity.

The Original (1958) Compact provided the following:

! Divided the Bear River into three main divisions: the Upper Division, theCentral Division, and the Lower Division; with subdivisions or sections createdin the Upper and Central Divisions. The Compact specifically identified whichriver flows and canal diversions are to be assigned to each of the divisions.

! Apportioned the direct flows of the Bear River and its tributaries between Utahand Wyoming in the Upper Division (upstream of Pixley Dam) and betweenIdaho and Wyoming in the Central Division (Pixley Dam to Stewart Dam).

! Did not specifically allocate the water in the Lower Division between the statesof Idaho and Utah. The Compact did, however, provide a mechanism whereina Utah water user may allege that because of diversions within Idaho, he is beingdeprived of water to which he is justly entitled and request distribution acrossstate line. If the Commission finds this to be the case, the Commission maydeclare a water emergency and establish a water delivery schedule in the LowerDivision based upon priority of rights without regard to state line.

! Defined the pre-Compact storage rights for each of the three states in reservoirsabove Bear Lake and established additional rights to store above Stewart Dam36,500 acre-feet of Bear River water in any water year. This 36,500 acre-feet ofstorage is referred to as "Original Compact storage" and was allocated to each ofthe states as follows:

Utah 17,750 acre-feetWyoming 17,750 acre-feetIdaho 1,000 acre-feet

! Reserved a portion of the storage capacity in Bear Lake for primary use by, andprotection of, irrigation uses and rights downstream from Bear Lake. Thiscompact-provided for "irrigation reserve" establishes minimum Bear Lake levels,which correspond to upstream storage development, below which Bear Lakecannot be drawn down only for power purposes.

O-8

AMENDED BEAR RIVER COMPACT

Proposed amendments to the Bear River Compact were approved by the Commission inDecember 1978 and the Amended Compact became law on February 8, 1980. Amendmentsprovide for the following principal changes to the 1958 Compact:

Amendment Highlights

! The allocation and distribution of direct flow rights between the various sectionsin the Upper and Central Divisions are unchanged from the 1958 Compact.

! Additional storage is granted above Bear Lake for 74,500 acre-feet, of which4,500 acre-feet is granted to Idaho, and 35,000 acre-feet is granted each to Utahand Wyoming. This storage, plus water appropriated (including ground water)and applied to beneficial use after January 1, 1976, is limited to an annualdepletion of 28,000 acre-feet of which Idaho is allocated 2,000 acre-feet and Utahand Wyoming are allocated 13,000 acre-feet each. This additional storage in theUpper and Central Division will not be allowed when the elevation of Bear Lakeis below 5911 feet (Utah Power and Light datum).

! Additional rights are granted to store water in the Upper and Central Divisionswhich would otherwise be spilled or bypassed from Bear Lake when all otherdirect flow and storage rights are satisfied. These storage rights are allocatedwith equal priority as follows: 6 percent to Idaho, 47 percent to Utah, and47 percent to Wyoming.

! The method for the declaration of a water emergency in the Lower Division andthe distribution of direct flow diversions by priority without regard to state lineis unchanged from the 1958 Compact.

! The water not applied to beneficial use prior to January 1, 1976, including groundwater tributary to the Bear River, is allocated on a depletion basis.

! In the Lower Division, Idaho is granted the first right to develop and deplete125,000 acre-feet. Utah is granted the second right to develop and deplete275,000 acre-feet. The next 150,000 acre-feet of water depletion will be dividedequally between Utah and Idaho. All water in excess of the above allocationswill be divided between Utah and Idaho, with Idaho receiving 30 percent andUtah 70 percent.

Compact Required Depletion Estimates

The amended Bear River Compact, as referenced above, states several of the newprovisions allowing for additional storage and use of waters subsequent to January 1, 1976 beadministered based on depletions. The Compact provides that Commission-approved proceduresshall be adopted to make such depletion estimates. Working under the direction of theCommission, the Technical Advisory Committee (TAC) was given the assignment to make thesedepletion estimates. First, at Commission meetings, the TAC presented base maps delineating

O-9

irrigation water usage up through January 1, 1976. The TAC then moved forward in theirassignment to make estimates of depletions subsequent to January 1, 1976.

The depletion estimates submitted by the states represented changes from January 1,1976 to January 1, 1990. At the November 1993 Commission meeting, the Commissionformally adopted these Commission-approved procedures which allow for common depletioncalculations. These Commission-approved procedures direct that the latest depletion estimatesshould be included in the Biennial Report. Figure O.3 represents the most recent depletionestimates.

ADMINISTRATION OF BEAR RIVER COMPACT

General

Provisions of the Compact are generally administered and enforced under the directionof the Bear River Commission. However, water rights within each state are adjudicated andadministered in accordance with state law, subject to limitations provided in the Compact.

O-10

Seasonal daily records are collected on about 130 diversions above Bear Lake by stateriver commissioners under the direction of their respective State Engineers and under the generalsupervision of the Commission's Engineer-Manager. These records include all of the diversionsfrom Bear River main stem and Smith’s Fork, as they are required to administer the Bear RiverCompact. Daily discharge records for canals in the Upper and Central Divisions are publishedin this biennial report and have been published in previous biennial reports.

The Engineer-Manager determines when, under provisions of the Compact, a wateremergency exists in the Upper or Central Divisions. Once a determination has been made of awater emergency, the Engineer-Manager is in weekly phone contact with state rivercommissioners as to flows and diversions and, at least once a week, allocates the water withinthe Upper and Central Divisions as provided for under the Compact. The Engineer-Manageralso inspects diversions in the field as needed to ensure the equitable apportionment of the waterof the Bear River as provided for under the Compact.

Storage

New Storage

The original Compact defines storage rights in existing reservoirs above Bear Lake andprovides for an additional storage allowance of 36,500 acre-feet annually. Idaho users onThomas Fork are allotted 1,000 acre-feet of this amount, and the remainder is divided equallybetween Wyoming and Utah.

The reservoirs listed in Figure O.4 have been constructed under the additional storageprovisions of the original Compact.

to 57,300 acre-feet. Allocated to this enlargement is: Utah, 18,000 acre-feet, including 6,686acre-feet depletion; and Wyoming, 2,960 acre-feet, including 871 acre-feet depletion.

Sulphur Creek Reservoir was enlarged in 1988 to a total capacity of 19,775 acre-feet.Allocated to this enlargement is 10,315 acre-feet (9,370 for municipal use), including 701 acre-feet for depletion.

Bear Lake

Article VI of the Compact provides an irrigation reserve level in Bear Lake below whichwater shall not be released solely for generation of power, except in emergency, but after releasefor irrigation, it may be used in generating power as it is conveyed to irrigation diversion works.The reserve is to be increased by designated amounts as additional storage, allocated by theoriginal Compact, is developed above Bear Lake. No development of new storage took placein 2003 or 2004, so the irrigation reserve elevation remained at 5914.61 feet with an activestorage content in Bear Lake of 794,000 acre-feet. This irrigation reserve elevation correspondsto 30,000 acre-feet of developed additional original Compact storage allocation.

Water Supply

The Commission uses three stream gages, one in each of the three river divisions, asgeneral indicators of the water supply during a given year in the respective divisions. Each ofthese three gages has a period of record beginning in 1943 and continues to the present. Thereis not a significant streamflow diversion above these three gages and, hence, they are used toapproximate natural flow conditions.

In the Upper Division, most of the Bear River streamflow originates on the north slopesof the Uinta Mountains and flows northward across the state line into Wyoming. The USGSUtah-Wyoming State Line Gage has been used as a good indicator gage of the water supplygenerally available above Bear Lake and, in particular, to the Upper Division.

Inflow from the Smith’s Fork to the Bear River in the Central Division often representshalf or more of the combined flow of the Bear River at this location. Therefore, the USGS gageon Smith’s Fork has been used by the Commission as an indicator of the available water supplyin the Central Division.

A large amount of the available water supply in the Lower Division originates and isdiverted in the Cache Valley. The major streams which are tributary to the Bear River in theCache Valley originate in the mountains on the east side of the valley. One of these tributaries,the Logan River, has been used by the Commission as a good indicator gage of the water supplyavailable for diversion in the Cache Valley and, in general, in the Lower Division. Severalcanals divert from the Logan River above the USGS gaging station. Hence, in order to gain agood record of approximately natural flow conditions, the canal diversion data are added to theUSGS stream gage data to generate a combined Logan River flow value. It is this combinedLogan River data which is used as an indicator of the general water supply in the LowerDivision.

As indicated above, the average discharge past these three indicator gages was wellbelow normal during both 2003 and 2004. Often of even greater significance is the water supplyavailable during the irrigation season, which averaged only about 50 percent of normal at thesethree indicator gages in 2003 and 2004.

O-12

The availability and use of storage water also makes a significant difference to the watersupply available for use during a given year. Because of the significant storage in the UpperDivision, if there is a full storage water supply, it can be a significant portion of the irrigationwater supply. Unfortunately, with depleted storage coming into the biennial period and limitedriver flows, Woodruff filled in neither year. During this biennial period, there were virtuallyno spills past Pixley during the irrigation season to augment the Central Division water supply.

Much of the flow of the Bear River in the Lower Division during the irrigation seasonis dominated by large storage water releases from Bear Lake. Hence, in assessing the watersupply available for users in the Lower Division, one needs to understand the storage wateravailability in Bear Lake. The combination of dramatically increased inflow and below normalstorage water demands in the late 1990's caused the water level to increase in Bear Lakedramatically from the early 1990's. This storage was much needed during these two dry wateryears. However, by the end of the biennial period, the carryover storage in Bear Lake wasnotably depleted. In both years of this biennial period the allocation of storage water in BearLake was limited by the Settlement Agreement.

Greater detail concerning the annual water supply available during the biennial periodis found in the second and third chapters of this report which specifically address the naturalflow and storage water supply for the 2003 and 2004 water years.

Streamflow Distribution

The administration of the distribution of the waters of the Bear River between the threeCompact states and the various subdivisions of the river, as defined by the Compact (the rivercrosses state lines five times), is defined by the original Compact. When the flow of the riverin the Upper and Central Divisions decreases to certain levels, the Engineer-Manager is todeclare a "water emergency" and supervise the allocation of water between the sections withinthe divisions of the river as directed by the Compact.

The Compact provides that in the Upper Division, which comprises all of the Basin fromits headwaters down to and including Pixley Dam, there shall be two sections administered inWyoming and two sections administered in Utah. The Compact provides that when the totalnatural flow diversion in the division, plus the flow passing Pixley Dam, is less than 1,250 cfs(divertible flow) a water emergency exists and such divertible flow is allocated to the sectionsas follows:

Upper Utah Section . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0.6 percentUpper Wyoming Section . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 49.3 percentLower Utah Section . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 40.5 percentLower Wyoming Section . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 9.6 percent

The Amended Compact further provides in Article IV.A.1.e. that:

If for any reason the aggregate of all diversions in a river section of theUpper Division does not equal the allocation of water thereto, the unusedportion of such allocation shall be available for use in the other riversections in the Upper Division in the following order: (1) In the otherriver section of the same State in which the unused allocation occurs; and(2) in the river sections of the other State. No permanent right of useshall be established by the distribution of water pursuant to thisparagraph e.

O-13

The Compact defines the Central Division as comprising that part of the Basin from Pixley Damdown to and including Stewart Dam (the point of diversion to Bear Lake). It includes onesection in Wyoming and one in Idaho.

Divertible flow in the Central Division is the sum of diversions from Smith’s Fork anddesignated tributaries, diversions from Bear River in the division, diversion to Bear Lake via theRainbow Inlet Canal, and flow passing Stewart Dam. A water emergency shall exist when thisdivertible flow is less than 870 cfs, or when the flow of the Bear River entering Idaho (gagingstation at Border) is less than 350 cfs. Wyoming diversions are limited to 43 percent ofdivertible flow during a water emergency.

Streamflow conditions were such that a water emergency, as defined by the Compact,was declared all but for several weeks during 2003 and from mid-June, 2004, until the end of theirrigation season. In the Central Division, a water emergency was found to exist during theentire irrigation period of both years and interstate regulation was imposed. For greater detailsconcerning the diversion and use of water during each of the irrigation seasons, consult thefollowing chapters specific to 2003 and 2004.

Interim procedures for the Lower Division Water Delivery were adopted several yearsago. No formal requests for the declaration of a water emergency in the Lower Division werereceived by the Commission in this biennial period.

Stream Gaging Program

The Commission has concluded a record of the streamflows in the Bear River drainageis most important as this record is needed: 1) for the measurement and subsequent distributionof waters during the irrigation season in compliance with the Compact; 2) to verify thecompliance of diversions with the Compact; 3) for the review of the Compact, as is requiredfrom time to time; and 4) for the three states to plan for water resource use and development.As an indication of the Commission's commitment to the stream-gaging program, theCommission allocated in the biennium approximately 50 percent of its budget to the stream-gaging program. PacifiCorp, the individual states, and water user organizations maintainadditional records of streamflows and canal diversions. A composite of all of the records isneeded to accurately reflect the waters available for use in the Bear River drainage.

All of the stream gages supported by the Commission are operated and maintained by theU.S. Geological Survey (USGS). The USGS is well recognized as a leader in stream-gagingtechnologies, and their records are used as a standard for planning, water distribution, and legalpurposes. The cooperative agreement between the Bear River Commission and the USGSprovides that both contribute equally to the funding of the program. The adequacy of the stream-gaging program is constantly reviewed by the Commission's TAC, by Commission members,and by the USGS.

Lists of the individual gages supported during the biennium and the records of key gagesduring the biennium are made a part of this report, and respective detail is provided in the 2003and 2004 chapters of this report. The locations of the gages that were in operation during thebiennial period are shown on Figure O.5.

BIENNIUM STATE ADMINISTRATION

Article XI of the Amended Compact provides applications for appropriation or changein water use within each state shall be in accordance with individual state law, except no suchapplication shall be approved if the effect will deprive water users within another state orincrease the depletion beyond that which is provided for under the Compact. This article furtherrequires that state officials report, in a format and at intervals established by the Commission,the status of their respective allocations and uses. The Commission has determined the bestformat for reporting such change in uses is the Biennial Report. Details of state water-relatedactivities are shown in the respective years' write-ups.

2003 WATER SUPPLY AND DISTRIBUTION REPORT

03-1


OVERVIEW

The 2003 water year marked the fourth year in a row of below normal water supply inthe Bear River Basin. The 2003 water supply was slightly better than the 2002 water supplyin all three Divisions, but was still very dry. Due to the drier than normal conditions during theprevious years, many of the reservoirs began the 2003 storage season below normal and werelimited in their storage opportunities. Due to the wetter than normal period in the late 1990'sand its significant storage capacity, Bear Lake began this drought period with significantstorage but was dramatically depleted in 2003.

Deficiencies in streamflow were found in both the Upper and the Central Divisionsduring the entire irrigation season, which led to the declaration of a water emergency in theUpper Division for most of the season and in the Central Division during the entire season.Runoff was low and early in both the Upper and Central Divisions and there was almost nopeak runoff noted in the Central Division. Streamflow remained low all season in all threedivisions.

WATER SUPPLY

Three stream gages, one in each division of the river, have been used by theCommission as indicator gages of the relative supply available for each of the divisions of theriver (see Stream Gaging Program section in the Overview chapter). The Utah-Wyoming StateLine and Smith’s Fork gages measure a major portion of the streamflow in the Upper andCentral Divisions, respectively. The Logan River is a major tributary to the Bear River inCache Valley, which is in the Lower Division. Specific discharges, as measured by the USGSfor the three gages during 2003, compared with the long-term averages, are summarized inFigure 2003.1 and are graphically illustrated in Figures 2003.2 through 2003.4 on thesubsequent pages.

Figure 2003.1 illustrates a summary of the volumetric discharge for each of these gagesfor the water year. As the water supply available during the irrigation season is most criticalfor filling the natural flow rights, the discharge as measured at these gages during the irrigationseason is also illustrated in Figure 2003.1.

Figures 2003.2 through 2003.4 show hydrographs for each of these three gagingstations. On each hydrograph, the mean daily flow during the irrigation season is plottedagainst the average of the mean daily flows for the period 1943 through 2003. The areabetween the 2003 hydrographs and the mean hydrographs represents the difference in volumeof water discharged during 2003 versus the long-term average. This volumetric difference isillustrated by the bar charts shown on each of the figures.

Figure 2003.1

As can be seen in Figure 2003.1, the annual discharge for the Upper Division (Utah-Wyoming State Line Gage) was 76 percent of the long-term average, and streamflow on Smith'sFork and the Logan River were 60 and 66 percent, respectively. More important to the naturalflow diversions than the streamflow during the water year is the streamflow during the irrigationseason of May through September. During this period, the water supply was approximately 72percent (Upper Division), 55 percent (Central Division), and 61 percent (Lower Division). Notonly was the water supply in the Upper Division during the irrigation season only 72 percent,but Woodruff Narrows Reservoir only filled to less than 40 percent of capacity, further reducingthe limited irrigation water supply. The Central Division faired even worse with no meaningfulstorage and limited spills past Pixley Dam, the irrigation water supplies were extremely limited.The Lower Division supply was only slightly better. During the irrigation season, the LoganRiver supplied only 61% of normal but many users in the Lower Division did better becauseof the heavy draft on storage in Bear Lake or other reservoirs.

STORAGE

Storage supplies along the Bear River have a notable impact on the water resourcesavailable for irrigation each year. Because of the prior drier than normal year, most reservoirsin the Bear River system began the 2003 storage season with depleted carryover supplies.Woodruff Narrows Reservoir is the largest reservoir in the Upper Division. However, Whitney,Sulphur Creek, and Woodruff Creek Reservoirs also provide for notable amounts of winterstorage.

Paragraph B of Article VI of the Amended Compact, which allows for additional storagerights above Stewart Dam, also has a provision which restricts storage to occur if the watersurface elevation at Bear Lake is below an elevation of 5911.0 (UP&L Datum). About half ofthe storage which is assigned to Woodruff Narrows Reservoir, from both the States of Utah andWyoming, fall under this provision of the Amended Compact. As Bear Lake was below thisstorage restriction elevation for all of 2003, this provision of the Compact was activated, andupstream storage restrictions were imposed. With the limited water supply and virtually nocarryover from the prior year, Woodruff Narrows Reservoir only filled to 22,020 acre-feet, orjust 38 percent of its capacity, in 2003.

Prior to 1997, a gage was maintained, with Commission funding, by the USGS onWoodruff Narrows Reservoir. The gage included a recorder which allowed for preservation ofdaily values. Since this time, periodic measurements have been kept by the Woodruff NarrowsReservoir Company in coordination with the Wyoming State Engineer’s Office. Figure 2003.5shows the maximum and minimum contents for the Woodruff Narrows Reservoir since itsenlargement in 1980. Values for 2003 are based on observations made by the WoodruffNarrows Reservoir Company.

The spillway crest of Woodruff Narrows Dam is at an elevation of 6454.5 feet; contentsof 57,300 acre-feet. Hence, contents above this amount represent uncontrolled storage, as thisstorage is only temporary and cannot be controlled by the reservoir company. Generally, duringspill periods, the reservoir company is often releasing significant flows through its outlet worksas well. Hence, though the total contents are uncontrolled, the proportion of water dischargingfrom the reservoir through the outlet works versus over the spillway is somewhat under thecontrol of the reservoir company. Both discharge to the Bear River below the dam but abovethe stream gage and it makes no difference to the total discharge into the Bear River.

There is no significant storage in the Central Division.

The largest and most significant storage reservoir in the Lower Division is Bear Lake,which is at the very top of the Lower Division. Bear Lake is operated as a storage reservoir byPacifiCorp. The Compact regulates various aspects of how PacifiCorp can manage the storageof water within Bear Lake. Figure 2003.6 summarizes the 2003 Bear Lake hydrologicinformation and significant operational events.

Figure 2003.6

Figure 2003.7 is a graph which shows the annual maximum and minimum elevations of BearLake since 1915. Bear Lake was far below elevations where downstream flooding might be ofconcern and it was operated in storage mode during the entire storage period. Figure 2003.8is an area plot showing the daily contents in Bear Lake over the past ten years. This hydrographmore dramatically shows the initial low Bear Lake water levels in the mid-1990's, followed byrapid lake level gains in the late 1990's, and now significant drops during the first four years ofthis century. As shown by the hydrograph, following the drier than normal period from 1987to 1994, dramatic increases in storage were achieved during the 1995, 1996 and 1997 wateryears and then maintained in 1998 and 1999, before the lake level began to fall in 2000. Witha low lake level and low forecasted inflow, the Settlement Agreement limited the irrigationallocation from Bear Lake to 181,000 af. In 2003, the net inflow to Bear Lake was -4,867 af,the 11th lowest of record. A high elevation of 5908.75' occurred on May 28, and then, followingthe discharge of 198,812 af of water (including irrigation release and the pass through of naturalflow), coupled with evaporation, the lake dropped more than four feet to end the season at5904.50', or 11% of the reservoir’s active contents.

STREAMFLOW DISTRIBUTION

General

The water administration in 2003 in the three divisions remained similar to prior years.There were no changes to the river commissioner/water master in each of the sections from theprevious year. Jack A. Barnett continued to serve as Engineer-Manager of the Bear RiverCommission. Each river commissioner/water master works under the direction of the respectiveState Engineer/Water Resources offices, but coordinates with the Commission's Engineer-Manager with regard to total diversions in each of the various sections as defined by theCompact.

During the 2003 irrigation season, the following river commissioners/water mastersmeasured water in their sections of the river:

DIVISION SECTION River Commissioner/Water Master

Upper: Upper Utah Don ShoemakerUpper Wyoming Don ShoemakerLower Utah Ron HoffmanLower Wyoming Kevin Payne

Central: Wyoming Kevin PayneIdaho Pete Peterson

Lower: Idaho Pete PetersonUtah Terry Gnehm

Early on it was recognized this would be a water short year and the Engineer-Managersent notice to the river commissioners/water masters to be ready for regulation. In late Aprilthe Upper Division went into regulation and remained in interstate regulation except for aperiod from mid-May to mid-June when the total divertible flow exceeded the water emergencythreshold. Similarly, based on call-in the last week of April, the Central Division wasdetermined to be in a water emergency and remained there for the entire irrigation season.

With regard to the distribution of flows in the Lower Division, the Commission hasnever been requested to become directly involved in the distribution of the available waterbetween Idaho and Utah, as provided for in the Compact. Therefore, a water emergency wasnot declared in the Lower Division and Lower Division diversions were not included in theweekly call-in and call-out schedule. The Interim Procedures for Lower Division WaterDelivery provide the framework of how the Commission would respond should it ever receivea petition to declare a water emergency in the Lower Division.

Due to the dryness of the year , there was a potential for the declaration of a wateremergency in the Lower Division. The states, Lower Division irrigators and PacifiCorp usedconference calls as a way of meeting weekly. This gave all involved a more sure knowledgeof the situation, it allowed for an understanding of the natural flow and the storage that was

03-12

remaining. Implementation of coordinated interstate computer accounting models by the Stateof Idaho and the State of Utah and the Bear Lake Settlement Agreement minimize thepossibility of a call on the river in the Lower Division.

Upper Division

The Upper Division divertible flow, as defined by the Compact, consists of a summationof the diversions of all of the canals in the four sections, plus waters bypassing Pixley Dam lessthat portion of water diverted by the canals which is attributable to storage releases fromWhitney, Sulphur Creek and Woodruff Narrows Reservoirs. The Compact provides that whenthe total divertible flow is less than 1250 cfs, a water emergency exists and the Commission isto implement regulation. In most years, as the irrigation season begins, the divertible flow, asdefined by the Compact, is less than 1250 cfs. However, except in drier years, due to the coolerand wetter conditions which often exist at this time of year, there is not a request for a wateremergency declaration. In 2003, the divertible flow was less than 1250 cfs in late April whenthe Commission received a request from Wyoming to impose interstate regulation. At this timeWoodruff Narrows had not yet stored all of its Original Compact storage allocation. Due to thecall, it was required to cease further storage. Sulphur Creek Reservoir had filled all of itsallocation, but Whitney had scarcely begun to store. Similar to Woodruff Narrows, due to theinterstate call, Whitney was not allowed additional storage. With time, Wyoming recognizedthat it would be advantageous to transfer storage from Sulphur Creek to Whitney, and hence,during early June, the river commissioner/water master for Wyoming exchanged approximately1800 af of storage water by making releases to natural flow from Sulphur Creek Reservoir inexchange for storage which was allowed to occur in Whitney Reservoir.

The water emergency which was in effect during most of the year is based on the weeklydiversions as called in by the respective river commissioner/water master. At the end of eachyear, these river commissioners/water masters submit to their respective State Engineers acomplete written report of water deliveries. It is this information which is presented in thegraphs and tables on the following pages and not the weekly totals called in during times ofregulation. The weekly call-in totals, which are received during the irrigation season, differslightly from the year-end data because of timing of call-ins and call-outs, shifts on canalratings and other factors.

Figures 2003.9 and 2003.10 on the following pages contain hydrographs which illustratethe Compact allocations and divertible flow to the Upper Wyoming Section and the Lower UtahSection of the Upper Division, respectively. As is portrayed on each of these hydrographs, theheavy solid line represents the total Compact defined divertible flow for the Upper Divisionduring the irrigation season. The dashed line represents the Compact allocation for theillustrated section, and the solid line represents the section’s actual divertible flow (totaldiversions less storage use).

Figure 2003.11 (pages 03-16 through 03-20) represents a compilation of each of thecanal’s diversions during 2003 in the Upper Division, based upon year-end rivercommissioners’/water masters’ reports. The data is displayed with one month's data per page.Totals of the canal diversions for each of the sections are shown below each section. Thesetotals show all water delivered to each canal and, therefore, include storage water. Thesummary at the bottom of each page shows divertible flow and allocations for each section of

03-13

the Upper Division. It is important to note that the divertible flow, as defined by the Compact,consists of only natural flow diversions. The values for the individual canals represent totaldiversions, which include both natural flow and storage water. Therefore, storage uses out ofWhitney, Sulphur Creek, and Woodruff Narrows Reservoirs have been subtracted from the totaldiversion amounts for the respective sections so that the totals tabulated at the bottom of eachmonth represent divertible flow as defined by the Compact. A positive number indicates thereservoir was releasing the shown value. A negative value shown for Woodruff Narrowsstorage indicates the reservoir was storing the indicated value. A negative value shown forstorage in Woodruff Narrows Reservoir represents the amount of water which needs to be addedinto the total divertible flow for any given day, as this is water which would otherwise beavailable for diversion in the Lower Utah and Lower Wyoming Sections.

In reviewing the graphs, one can see how the water supply was affected by a mid-Junerainy period which put the Upper Division again out of a water emergency and created a two-humped runoff. The divertible flow is also influenced by return flows from reservoir releases.In the accounting of divertible flow, storage releases are subtracted from the total even if suchreleases have not reached downstream canals and been diverted from the river. Based on areview of the allocation and diversion data one can see that regulation occurred in substantialconformance with the Compact during the irrigation season.

Central Division

As with the Upper Division, the natural flow water supply in the Central Division wasalso well below normal again. In late April, Idaho requested that a call-in of diversions be madeto determine if a water emergency was warranted. Based on that call-in, on April 25, with adivertible flow of less than 400 cfs, a water emergency was declared and the Central Divisionremained in interstate regulation during the remainder of the season. With very little spills pastPixley and no meaningful storage in the Central Division, the irrigators needed to get by withan extremely limited water supply. There was good cooperation from the rivercommissioners/water masters in appropriately dividing up the limited supply. Due to thecritical year, several changes in water measurement were implemented. Due to questionsregarding the accuracy of the Rainbow Inlet Canal gage at extremely low flows, directmeasurements of the leakage into the Rainbow Inlet Canal were made just below RainbowDam. Also, each week following call-in, Idaho faxed to the Commission its computer printoutsof the weekly diversion totals.

The Compact provides that a water emergency may be declared when the divertible flowin the Central Division drops below 870 cfs. As the divertible flow was well below the 870 cfstrigger during the entire season, a water emergency existed (the highest the divertible flowreached was 790 cfs on June 3). A water emergency may also be declared in the CentralDivision if the flow rate at the Border Gage drops below 350 cfs. The flow at the Border Gagewas only above the 350 cfs threshold during eight days over the entire season. The Compactprovides that once a water emergency is deemed to exist, the State of Wyoming is to berestricted to 43 percent of the total divertible flow. The remaining 57 percent is available foruse within Idaho.

Figures 2003.12 and 2003.13 graphically illustrate the Central Division's divertible flowand the respective allocations and diversions by the Wyoming and Idaho Sections. The flowpast the Border Gage is not illustrated on these figures, as it never impacted river regulation andthe additional line would only serve to confuse the data illustrated by the hydrographs. It isimportant to note that on Figure 2003.13, the line labeled as "Available to Idaho" represents thesummation of diversions within the State of Idaho, as well as flow passing Stewart Dam anddiversion to the Rainbow Inlet Canal. As the Compact provides that 57 percent of the CentralDivision's divertible flow shall be available for use within Idaho, this line is used to showwhether such provision of the Compact was met. However, the Compact also provides that ifIdaho elects to not divert into its canals its full entitlement, a portion of its allocation can passinto the Lower Division via the Rainbow Inlet Canal or Stewart Dam. Data for this hydrographare based on the river commissioner/water master annual reports to their respective state wateragencies.

Figure 2003.14 (pages 03-24 through 03-28) shows a compilation of daily canaldiversions as provided by the respective river commissioners/water masters. The Wyoming andIdaho Sections' diversions and allocations are tabulated and summarized at the bottom of eachpage. The pages are divided such that there is a month's data per page. As the flow of the BearRiver at the Border Gage could also be critical to the declaration of a water emergency, asdefined by the Compact, this gage's data is also shown in these tables. Based on a review of theyear-end data, the Central Division was reasonably regulated in conformance with the Compact.

Lower Division

Distribution in the Lower Division is cooperatively managed by the states ofIdaho andUtah through their river commissioners in conjunction with PacifiCorp as prescribed by the BearLake Settlement Agreement. In 2003, an Addendum to the Settlement Agreement was signedto resolve and clarify accounting of system operating losses and transit losses. As a result, in2003, the allocation to irrigation, including decreed transit losses was 181,000 acre-feet and17,000 acre-feet was allocated for system operating losses, for a total allocation ofl98,000 acrefeet to be released from Bear Lake, measured at the Outlet gage.

The dredging of the inlet channel and sandbar in front of the inlet channel to the LiftonPump Plant in Bear Lake was complete before the irrigation season began. This dredgingallowed approximately 190,000 acre-feet to be pumped from Bear Lake to water usersdownstream. Deducting decreed adjustments for the natural yield of the Bear Lake area,credited releases were 183,569 acre-feet ofwhich 167,995 acre-feet were delivered with transitlosses of5889 acre-feet and system operating losses of9685 acre-feet. This left 14,431 acrefeet in Bear Lake for lake recovery and future allocation.

Water right accounting during the 2003 irrigation season was performed by the statesusing the "Interstate" accounting models. The Interstate models, in addition, to distributingnatural flow according to the Dietrich decree in Idaho and the Kimball decree in Utah accountsfor storage water use. The program includes water rights in both states and distributes allocablenatural flows without regard to the state line.

The water supply has required that both Idaho and Utah coordinate data for the operationofthe interstate accounting models. Conference calls were held bi-weeklyto discuss the resultsof the model and river operation. This coordination has increased communication and averteda potential call on the river.

STATE WATER ACTIVITIES

Article XI of the Amended Compact provides that applications for appropriation orchange in water use within each state shall be in accordance with individual state law, exceptno such application shall be approved if the effect will deprive water users within another stateor increase the depletion beyond that which is provided for under the Compact. This articlefurther requires that state officials report, in a format and at intervals established by theCommission, the status of their respective allocations and uses. The Commission hasdetermined the best format for reporting such changes in use is the Biennial Report. Thisportion of the Biennial Report is primarily where the required Article XI information isprovided. The following subsections relate specific major Bear River water-related activitieswhich occurred in each of the states, as reported by the state, during the 2003 water year.

Idaho

Water right accounting during the 2003 irrigation season was performed using the“Interstate” accounting model. Idaho adopted the Interstate model beginning with the 2000season. The Interstate model, in addition to distributing natural flow according to the Terrelland Dietrich decrees in Idaho, includes water rights downstream in Utah. Allocable naturalflows are distributed by the program without regard to the state line.

As Bear Lake levels continued to decline due to continued drought conditions, storageallocated to irrigators under the Settlement Agreement declined as well. During the 2003season, Last Chance used 26,202 acre-feet of its allocation of 34,189. West Cache used 20,627acre-feet of its allocation of 22,016; Cub River Pumps used 14,945 acre-feet against itsallocation of 16,319; and the Idaho small irrigators used 3,964 acre-feet of their allocation of5,722 acre-feet.

Water right activities in Idaho during 2003 were primarily in the Malad sub-basin (IdahoBasin 15) of the Lower Division. Frequent shortages of surface water and the decommissioningof St. Johns Reservoir in 2001 have prompted many users to seek ground water supplies forlands that were already irrigated. In the Malad Basin in 2003, permits (ground water) were usedfor the supplemental irrigation of 1,371 acres and new irrigation of 328 acres. In Idaho Basin13, the main Bear River below Alexander, only one permit was issued, that being for a non-consumptive pond diversion.

There was no activity in water right Idaho Basin 11 in 2003. This basin includes thatportion of the Lower Division above Alexander, as well as the Idaho portion of the CentralDivision.

Utah

The dredging of the inlet channel and sandbar in front of the inlet channel to the LiftonPump Plant in Bear Lake was complete before the irrigation season began. This dredging

03-31

allowed approximately 180,000 acre-feet to be pumped from Bear Lake to water usersdownstream.

The Division of Water Resources inventoried the Bear River Basin (Utah portion) of itsland use mapping. The publishing of the Revised Bear River Basin State Water Plan was halteduntil the results were compiled. This updated Bear River Basin State Water Plan is scheduledto be published in January, 2004.

A cloud seeding project to increase snowpack has been ongoing since 1989 in the LowerDivision in Eastern Box Elder County and Cache County. The winter storm systems in theseareas are being seeded with ground-based generators using silver iodide. The Bear River WaterConservancy District and Cache County cost-shared (approximately 58/42) with the Utah Boardof Water Resources in the cloud seeding project during the 2003 water year.

The water supply has required that both Idaho and Utah coordinate data for theoperation of the interstate accounting models. Conference calls were held bi-weekly to discussthe results of the model and river operation. This coordination has increased communicationand averted a potential call on the river.

Wyoming

The 2003 water year began with low soil moisture content and severely below averagesnowpack throughout the entire Bear River Basin. Snow left early in March and springprecipitation was well below normal. Hard frosts in June forced first crop hay to be cut early.July and August temperatures were well above average. Late rains in August and Septemberhelped green fall pasture.

Bear Lake went below the 5911 elevation and this triggered restrictions in storage inupstream reservoirs. Interstate regulation of direct flow was activated on April 25th in theCentral Division based on a call from Idaho.

In the Lower Wyoming Section of the Upper Division, irrigators requested interstateregulation for the Upper Division before runoff, forcing storage to cease in all Compactreservoirs in the Upper Division on April 28th. Even after runoff briefly lifted the UpperDivision out of the interstate water emergency, storage was not allowed to resume because ofunfulfilled direct flow rights in the Randolph area. This caused unprecedented storagerestrictions to be imposed on Whitney Reservoir. By agreement, early capture of 2,404 acre-feet in Sulphur Creek Reservoir was released to allow an equal amount of otherwise prohibitedcapture by Whitney Reservoir. Woodruff Narrows Reservoir Company, in addition to generallypassing through regulated inflows for prior direct flow rights, began delivering stored wateraccording to specific delivery orders from shareholders.

Field reconnaissance and meetings were held with the University of Wyoming forstudying conveyance losses, return flows, and lag times from Woodruff Narrows down toPixley.

Measuring devices were required and installed on most Compact diversions inWyoming, speeding regulation rounds by the Water Commissioners and increasing accuracy.

STREAM GAGING

As was indicated in the "Overview" chapter of this report under the subsectionconcerning the "Stream Gaging Program" (see page O-14), the Bear River Commissionparticipates in a cooperative contract with the USGS for the maintenance of stream gages onthe Bear River and significant tributaries. Also, some of the states participate with the USGSin additional Bear River gages, as does PacifiCorp. The Commission believes the collectionof data concerning stream flows in the Bear River system is very important and allocates abouthalf of its annual budget in support of the cooperative stream gaging program with the U.S.Geological Survey. However, costs continue to increase and so the Commission is constantlyreviewing the stream gaging program to determine if all of the stations supported are necessaryto help the Commission fulfill the responsibilities assigned to it by the Compact. There wereno changes to the Commission’s stream gaging program in 2003.

During 2003, a total of 31 gages were maintained on the Bear River system. Of these32 gages, 9 were part of a cooperative effort between the Bear River Commission and theUSGS. PacifiCorp maintained 15 gages on the Bear River system during 2003. The State ofUtah cooperated with the USGS for the maintenance of three stream gages in 2003, Idaho onegage, Evanston and Logan Cities each cooperated with the USGS in the maintenance of onegage and the USGS funded one gage. Figure 2003.15 shows a tabulation of these gages and theentities which participated in the operation and funding of each gage. The approximatelocations of the stream gages are shown on Figure O.5 in the Overview section of this report.

Publication of the streamflow records for 12 of the gages in this report were consideredto be of significant value to the Commission and are included as pages 03-34 through 03-45.

OVERVIEW

The 2004 water year continued the trend as the fifth straight year of a below normalwater supply in the Bear River Basin. The 2004 water supply was drier than the 2003 watersupply. Due to the drier than normal conditions during the previous four years, many of thereservoirs began the 2004 storage season well below normal and were limited in their storageopportunities. Bear Lake had been significantly depleted during 2000, 2001, 2002 and 2003,and began the storage season at an elevation of 5904.48 feet.

Deficiencies in streamflow were found in both the Upper and the Central Divisionsduring the irrigation season. The Compact defined total divertible flow in each of thesedivisions remained below the water emergency triggers for the entire irrigation season, thougha request for interstate regulation was not received until mid-June. Runoff in all three divisionswas early and low, with almost no peak-flow period and the streamflow in all three divisionswas well below normal for the remainder of the season.

WATER SUPPLY

Three stream gages, one in each division of the river, have been used by theCommission as indicator gages of the relative supply available for each of the divisions of theriver (see Stream Gaging Program section in the Overview chapter). The Utah-Wyoming StateLine and Smith’s Fork gages measure a major portion of the streamflow in the Upper andCentral Divisions, respectively. The Logan River is a major tributary to the Bear River inCache Valley, which is in the Lower Division. Specific discharges, as measured by the USGSfor the three gages during 2004, compared with the long-term averages, are summarized inFigure 2004.1 and are graphically illustrated in Figures 2004.2 through 2004.4 on thesubsequent pages.

Figure 2004.1 illustrates a summary of the volumetric discharge for each of these gagesfor the water year. As the water supply available during the irrigation season is most criticalfor filling the natural flow rights, the discharge as measured at these gages during the irrigationseason is also illustrated in Figure 2004.1.

Figures 2004.2 through 2004.4 show hydrographs for each of these three gagingstations. On each hydrograph, the mean daily flow during the irrigation season is plottedagainst the average of the mean daily flows for the period 1943 through 2004. The areabetween the 2004 hydrographs and the mean hydrographs represents the difference in volumeof water discharged during 2004 versus the long-term average. This volumetric difference isillustrated by the bar charts shown on each of the figures.

2004 Water Supply Summary by Division

2004 WATER YEAR(Discharge in Acre-feet)





2004 IRRIGATION SEASONMAY - SEPTEMBER(Discharge in Acre-feet)





Figure 2004.1

As can be seen in Figure 2004.1, the annual discharge for the Upper Division (Utah-Wyoming State Line gage) was 64 percent of the long-term average, and streamflow on Smith'sFork and the Logan River were 66 and 61 percent, respectively. More important to the naturalflow diversions than the streamflow during the water year is the streamflow during the irrigationseason of May through September. During this period, the water supply was approximately 57percent (Upper Division), 56 percent (Central Division), and 56 percent (Lower Division). Notonly was the water supply in the Upper Division during the irrigation season only 57 percentof normal (even lower than 2003), but Woodruff Narrows Reservoir only filled to less than halfof its capacity, further reducing the limited irrigation water supply. The Central Division fairedsimilarly with 56 percent of normal streamflow which was about the same as the prior year.With no meaningful storage in the Central Division and limited spills past Pixley Dam, theirrigation water supplies were extremely limited. The Lower Division supply was similar andwith restrictions on Bear Lake usage there was also a limited water supply.

STORAGE

Storage supplies along the Bear River have a notable impact on the water resourcesavailable for irrigation each year. Because of the prior three drier than normal years, mostreservoirs in the Bear River system began the 2004 storage season with depleted carryoversupplies. Woodruff Narrows Reservoir is the largest reservoir in the Upper Division. However,Whitney, Sulphur Creek, and Woodruff Creek Reservoirs also provide for notable amounts ofwinter storage.

Paragraph B of Article VI of the Amended Compact, which allows for additional storagerights above Stewart Dam, also has a provision which restricts storage to occur if the watersurface elevation at Bear Lake is below an elevation of 5911.0 (UP&L Datum). About half ofthe storage which is assigned to Woodruff Narrows Reservoir, from both the States of Utah andWyoming, fall under this provision of the Amended Compact. Bear Lake was below thisstorage restriction elevation for all of 2004, thus, this provision of the Compact was activatedand upstream storage restrictions were imposed. With the limited water supply and virtuallyno carryover storage from the prior year, Woodruff Narrows Reservoir only filled to just over22,000 acre-feet, or less than half of its capacity, in 2004 and then ended the season with lessthan 6,400 acre-feet of storage to carry over to the next year.

Prior to 1997, a gage was maintained, with Commission funding, by the USGS onWoodruff Narrows Reservoir. The gage included a recorder which allowed for preservation ofdaily values. Since this time, periodic measurements have been kept by the Woodruff NarrowsReservoir Company in coordination with the Wyoming State Engineer’s Office. Figure 2004.5shows the maximum and minimum contents for the Woodruff Narrows Reservoir since itsenlargement in 1980. Values for 2004 are based on observations made by the WoodruffNarrows Reservoir Company.

The spillway crest of Woodruff Narrows Dam is at an elevation of 6454.5 feet; contentsof 57,300 acre-feet. Hence, contents above this amount represent uncontrolled storage as thisstorage is only temporary and cannot be controlled by the reservoir company. Generally, duringspill periods, the reservoir company is often releasing significant flows through its outlet worksas well. Hence, though the total contents are uncontrolled, the proportion of water dischargingfrom the reservoir through the outlet works versus over the spillway is somewhat under thecontrol of the reservoir company. Both discharge to the Bear River below the dam but abovethe stream gage and it makes no difference to the total discharge into the Bear River.

There is no significant storage in the Central Division.

The largest and most significant storage reservoir in the Lower Division is Bear Lake,which is at the very top of the Lower Division. Bear Lake is operated as a storage reservoir byPacifiCorp. The Compact regulates various aspects of how PacifiCorp can manage the storageof water within Bear Lake. Figure 2004.6 summarizes the 2004 Bear Lake hydrologicinformation and significant operational events.

Figure 2004.6

Figure 2004.7 is a graph which shows the annual maximum and minimum elevationsof Bear Lake since 1915. With a beginning elevation approximately more than 14 feet belowthe operating target, Bear Lake was operated in storage mode during the entire storage period.Figure 2004.8 is an area plot showing the daily contents in Bear Lake over the past ten years.This hydrograph more dramatically shows the initial low Bear Lake water levels in the mid-1990's, followed by rapid lake level gains in the late 1990's and, now, significant drops duringthe first four years of this century. As shown by the hydrograph, following the drier thannormal period from 1987 to 1994, dramatic increases in storage were achieved during the 1995,1996 and 1997 water years and then maintained in 1998 and 1999, before the lake level beganto fall in 2000. With a very limited water supply and low forecasts, the irrigation allocationpursuant to the Settlement Agreement was only 85,000 af. In 2004, the net inflow to Bear Lakewas 27,133 af. During the storage season the lake only rose a little over one and half feet toreach a high elevation of 5905.72 feet which occurred on May 16 and then, following thedischarge of 101,282 af (85,034 af of which was irrigation release), coupled with evaporation,the lake dropped more than two and half feet to end the season at 5903.13 feet, or 5 percent ofthe reservoir’s active contents.

STREAMFLOW DISTRIBUTION

General

The water administration in 2004 in the three divisions remained similar to prior years.There were no changes to the river commissioners in each of the sections from the previousyear. Jack A. Barnett continued to serve as Engineer-Manager of the Bear River Commission.Each river commissioner works under the direction of the respective State Engineers' offices,but coordinates with the Commission's Engineer-Manager with regard to total diversions ineach of the various sections as defined by the Compact.

During the 2004 irrigation season, the following river commissioners measured waterin their sections of the river:

DIVISION SECTION RIVER COMMISSIONER

Upper: Upper Utah Don ShoemakerUpper Wyoming Don ShoemakerLower Utah Ron HoffmanLower Wyoming Kevin Payne

Central: Wyoming Kevin PayneIdaho Pete Peterson

Lower: Idaho Pete PetersonUtah Terry Gnehm

Early on it was recognized this would be a water short year and the Engineer-Managersent notice to the river commissioners to be ready for regulation. Though flows were lowenough to declare a water emergency during most of the year in the Upper Division, a requestfor interstate regulation was not received until mid-June. On the other hand, based on call-invalues, the Central Division was placed in a water emergency on April 23 and remained therefor the entire irrigation season.

With regard to distribution of flows in the Lower Division, the Commission has neverbeen requested to become directly involved in the distribution of the available water betweenIdaho and Utah, as provided for in the Compact. Therefore, a water emergency was notdeclared in the Lower Division, and Lower Division diversions were not included in the weeklycall-in and call-out schedule. The Interim Procedures for Lower Division Water Deliveryprovide the framework of how the Commission would respond should it ever receive a petitionto declare a water emergency in the Lower Division.

04-12

Upper Division

The Upper Division divertible flow, as defined by the Compact, consists of a summationof the diversions of all of the canals in the four sections, plus waters bypassing Pixley Dam, lessthat portion of water diverted by the canals which is attributable to storage releases fromWhitney, Sulphur Creek and Woodruff Narrows Reservoirs. The Compact provides that whenthe total divertible flow is less than 1250 cfs, a water emergency exists. In most years, as theirrigation season begins, the divertible flow, as defined by the Compact, is less than 1250 cfs.However, except in drier years, due to the cooler and wetter conditions which often exist at thistime of year, there is not a request for a water emergency declaration. This was the case in2004. The divertible flow was less than 1250 cfs for the entire irrigation season, yet a requestfor interstate regulation was not received until mid-June when Wyoming requested that theCommission review the flows and deliveries and determine whether or not a water emergencyexisted. On June 15 the first interstate regulation occurred and continued through the remainderof the season.

During years when a water emergency has been declared, the regulation of the river isbased on the weekly diversions as called in by the respective river commissioners. At the endof each year, these river commissioners submit to their respective State Engineers a completewritten report of water deliveries. It is this information which is presented in the graphs andtables on the following pages and not the weekly totals called-in during times of regulation.The weekly call-in totals, which are received during the irrigation season, differ slightly fromthe year-end data because of timing of call-ins and call-outs, shifts on canal ratings and otherfactors.

Figures 2004.9 and 2004.10 on the following pages contain hydrographs which illustratethe Compact allocations and divertible flow to the Upper Wyoming Section and the Lower UtahSection of the Upper Division, respectively. As is portrayed on each of these hydrographs, theheavy solid line represents the total Compact defined divertible flow for the Upper Divisionduring the irrigation season. The dashed line represents the Compact allocation for theillustrated section, and the solid line represents the section’s actual divertible flow (totaldiversions less storage use).

Figure 2004.11 (pages 04-16 through 04-20) represents a compilation of each of thecanal diversions during 2004 in the Upper Division, based on year-end rivercommissioners’/water masters’ reports. The data is displayed with one month's data per page.Totals of the canal diversions for each of the sections are shown below each section. Thesetotals show all water delivered to each canal and, therefore, include storage water. Thesummary boxes at the bottom of each page show divertible flow and allocations for each sectionof the Upper Division. It is important to note that the divertible flow, as defined by theCompact, consists of only natural flow diversions. The values for the individual canalsrepresent total diversions, which include both natural flow and storage water. Therefore,storage uses out of Whitney, Sulphur Creek, and Woodruff Narrows Reservoirs have beensubtracted from the total diversion amounts for the respective sections so that the totalstabulated in the box at the bottom of each month represent divertible flow as defined by theCompact. A positive number indicates the reservoir was releasing the shown value. A negativevalue shown for Woodruff Narrows storage indicates the reservoir was storing the indicatedvalue. A negative value shown for storage in Woodruff Narrows Reservoir represents theamount of water which needs to be added into the total divertible flow for any given day, as this

04-13

is water which would otherwise be available for diversion in the Lower Utah and LowerWyoming Sections.

In reviewing the graphs, one can see how there really was not much of a runoff or peakflow in 2004. The total divertible flow never reached 1,250 cfs. At best there was a relativelyhigher flow period from mid-May to late June. During the first part of the season the users werestill storing in the reservoirs. Releases from storage from Woodruff Narrows Reservoir beganin early June and continued for several weeks. The return flows from the use of the storedwater had the effect of holding the divertible flow up until early July when it began to drop offrapidly. Many of the canals then significantly reduced their diversions. One can see fromFigure 2004.9 that the Upper Wyoming Section diverted essentially what would have been itsallocation even when a water emergency had not been declared.

Central Division

As with the Upper Division, the natural flow water supply in the Central Division wasalso well below normal again. On April 20, Idaho requested that a call-in of diversions be madeto determine if a water emergency was warranted. Based on that call-in, on April 23, with adivertible flow of a little over 400 cfs, a water emergency was declared and the CentralDivision remained in interstate regulation during the remainder of the season. With very littlespills past Pixley and no meaningful storage in the Central Division, the irrigators needed to getby again with an extremely limited water supply. There was good cooperation from the rivercommissioners in appropriately dividing up the limited supply. Due to the critical year, theseveral changes in water measurement implemented in the prior year were continued. Due toquestions regarding the accuracy of the Rainbow Inlet Canal gage at low flows, directmeasurements of the leakage into the Rainbow Inlet Canal were made just below RainbowDam. Each week following call-in, Idaho faxed to the Commission its computer printouts ofthe weekly diversion totals.

The Compact provides that a water emergency may be declared when the divertible flowin the Central Division drops below 870 cfs. As the divertible flow was well below the 870 cfstrigger the entire season, a water emergency existed during the full irrigation season. Thehighest that the divertible flow reached was 586 cfs. A water emergency may also be declaredin the Central Division if the flow rate at the Border Gage drops below 350 cfs. The flow at theBorder Gage was only above the 350 cfs threshold for three days the entire season. TheCompact provides that once a water emergency is deemed to exist, the State of Wyoming is tobe restricted to 43 percent of the total divertible flow. The remaining 57 percent is availablefor use within Idaho. With the good cooperation from the river commissioners/water mastersand relatively flat water supply, total delivery to the two states was within a half a percent ofthe Compact allocations.

Figures 2004.12 and 2004.13 graphically illustrate the Central Division's divertible flowand the respective allocations and diversions by the Wyoming and Idaho Sections. The flowpast the Border Gage is not illustrated on these figures, as it never impacted river regulation.It is important to note that on Figure 2004.13, the line labeled as "Available to Idaho" representsthe summation of diversions within the State of Idaho, as well as flow passing Stewart Dam anddiversion to the Rainbow Inlet Canal. As the Compact provides that 57 percent of the CentralDivision's divertible flow shall be available for use within Idaho, this line is used to showwhether such provision of the Compact was met. However, the Compact also provides that ifIdaho elects to not divert into its canals its full entitlement, a portion of its allocation can passinto the Lower Division via the Rainbow Inlet Canal or Stewart Dam. Data for this hydrographare based on the river commissioners'/water masters’ annual reports to their respective statewater agencies.

Figure 2004.14 (pages 04-24 through 04-28) shows a compilation of daily canaldiversions as provided by the respective river commissioners. The Wyoming and IdahoSections' diversions and allocations are tabulated and summarized at the bottom of each page.The pages are divided such that there is one month's data per page. As the flow of the BearRiver at the Border Gage could also be critical to the declaration of a water emergency, asdefined by the Compact, this gage's data are also shown in these tables. Based on a review ofthe year-end data, in general the Central Division was reasonably regulated in conformancewith the Compact.

Lower Division

Distribution in the Lower Division was cooperatively managed by the states of Idahoand Utah through their river commissioners in conjunction with PacifiCorp as prescribed by anAmended and Restated Bear Lake Settlement Agreement, which was signed in 2004. Theannual allocation to irrigation, including decreed transit losses was 85,000 acre-feet and 17,000acre-feet was allocated for system operating losses, for a total allocation of 102,000 acre-feetto be released from Bear Lake, measured at the Outlet gage.

The dredging of the inlet channel and sandbar in front of the inlet channel to the LiftonPump Plant in Bear Lake was complete before the irrigation season began. This dredgingallowed approximately 100,000 acre-feet to be pumped from Bear Lake to water usersdownstream. Deducting decreed adjustments for the natural yield of the Bear Lake area,credited releases were 85,034 acre-feet of which 70,698 acre-feet were delivered with transitlosses of 2522 acre-feet and system operating losses of 11,814 acre-feet. This left 16,966 acre-feet in Bear Lake for lake recovery and future allocation.

Water right accounting during the 2004 irrigation season was performed by the statesusing the "Interstate" accounting models. The Interstate models, in addition, to distributingnatural flow according to the Dietrich decree in Idaho and the Kimball decree in Utah accountsfor storage water use. The program includes water rights in both states and distributesallocable natural flows without regard to the state line.

The water supply has required that both Idaho and Utah coordinate data for theoperation of the interstate accounting models. Conference calls were held bi-weekly to discussthe results of the model and river operation. This coordination has increased communicationand averted a potential call on the river.

STATE WATER ACTIVITIES

Article XI of the Amended Compact provides that applications for appropriation orchange in water use within each state shall be in accordance with individual state law, exceptno such application shall be approved if the effect will deprive water users within another stateor increase the depletion beyond that which is provided for under the Compact. This articlefurther requires state officials report, in a format and at intervals established by theCommission, the status of their respective allocations and uses. The Commission hasdetermined the best format for reporting such changes in use is the Biennial Report. Thisportion of the Biennial Report is primarily where the required Article XI information isprovided. The following subsections relate specific major Bear River water-related activitieswhich occurred in each of the states, as reported by the state, during the 2004 water year.

Idaho

Water right accounting during the 2004 irrigation season was performed using the"Interstate" accounting program, as it has since the 2000 season. The Interstate model, inaddition to distributing natural flow according to the Terrell and Dietrich decrees in Idaho,includes water rights downstream in Utah. Allocable natural flows are distributed by theprogram without regard to the state line.

As a result of the low level of Bear Lake and the continuing drought, the 2004 allocationof storage water to irrigators in the Lower Division was only about 37 percent of a full amount.Idaho irrigation entities allocations and uses, respectively, were as follows: Last Chance,15,907 acre-feet and 12,245 acre-feet; West Cache, 10,194 acre-feet and 10,249 acre-feet; CubRiver, 7,464 acre-feet and 6,308 acre-feet. The Idaho small irrigators were allocated 2,458acre-feet and used 1,510 acre-feet.

Water right activity in Idaho during 2004 was fairly light and involved only groundwater. In Idaho Basin 13, the main Bear River below Alexander, there was one applicationreceived for the supplemental irrigation of 149 acres. In the Malad River Basin, a commercialapplication for 3.0 cfs was received for a truck plaza and RV park. Also in the Malad IdahoBasin 15, applications were received for the irrigation of 5 acres of new land and 100 acres ofsupplemental irrigation.

Permits were issued for a 1.4 cfs multi-family domestic and commercial use near FishHaven. In Idaho Basin 15, the Malad, permits were issued for the irrigation of 55 acres of newland and for the supplemental irrigation of 373 acres.

The only licenses issued in 2004 were for the supplemental irrigation of 401 acres nearBennington and the irrigation of 3 acres of new land at the Bern Cemetery. Both of these arein Idaho’s water right Basin 11 but are in the Lower Division.

Utah

The dredging of the inlet channel and sandbar in front of the inlet channel to the LiftonPump Plant in Bear Lake was complete before the irrigation season began. This dredgingallowed approximately 80,000 acre-feet to be pumped from Bear Lake and delivered to waterusers downstream.

The Division of Water Resources inventoried the Bear River Basin (Utah portion) of itsland use mapping in 2003. This land use data, along with new municipal and industrial wateruse, was compiled and published in the Bear River Basin Planning for the Future, Utah StateWater Plan in January 2004.

A cloud seeding project to increase snowpack has been ongoing since 1989 in the LowerDivision in Eastern Box Elder County and Cache County. The winter storm systems in theseareas are being seeded with ground-based generators using silver iodide. Bear River WaterConservancy District and Cache County cost shared (approximately 62/38) with the Utah Boardof Water Resources in the cloud seeding project during the 2004 water year.

The last two years there has been significant coordination between users on the BearRiver. Bear River water users have used twice a week conference calls to manage releases anddiversions.

Woodruff Creek Irrigation Company is looking at enlarging Woodruff Creek Reservoirwhile making modifications to make the structure more safe.

The Upper Division of the Bear River automated gages through a coordinated effortbetween users and state and federal agencies.

Wyoming

Although the ongoing drought continued in 2004 with snowpack well below average,rain showers in June and July immensely helped summer range conditions and irrigators whosewater supply was restricted and regulated early. Interstate regulation in the Central Divisionwas formally imposed on April 23, 2004.

Continued low levels in Bear Lake again triggered monitoring at upstream WoodruffNarrows Reservoir. Wyoming transferred an additional 5,136 acre-feet of Compact storage ona one time basis into this reservoir. Unrestricted Whitney Reservoir only filled to 63% whileSulphur Creek, Broadbent, and Ben Reservoirs filled to capacity (the latter two fromdocumented Green River basin imports). In addition to its large carryover, Sulphur CreekReservoir’s fill came from storage transfer, which was later released to maximize Compactdivertible flow allocations. With most of this year’s transferable Original Compact storageallocation being moved to Woodruff Narrows Reservoir, Lower Wyoming Section shareholdersin the Upper Division were again allowed shepherded storage deliveries by Woodruff NarrowsReservoir Company, which also provided additional diversions in that area. Although interstateregulation was not officially imposed in the Upper Division until June 14, the Compact-formuladivision of water was voluntarily managed between Wyoming and Utah beforehand to allow

04-32

Whitney and Woodruff Reservoirs to continue storing after divertible flow levels could havebeen imposed by Compact administration if a water emergency had been called for early in theseason.

The University of Wyoming study is moving forward to track reservoir deliveries,conveyance losses, and return flows below Woodruff Narrows Reservoir. Digital data loggerswere installed this spring and measurements made at three different temporary stream gagelocations on the river in Utah. Funding through the State Engineer’s Office was made availableto upgrade the old A-35 recorders in the Upper Wyoming Section with digital loggers.

Following Utah’s lead with Bureau of Reclamation cost-share in the Randolph area,internet-accessible telemetry is progressing and will be attempted on various Wyomingdiversions throughout the Central and Upper Divisions.

New depletions issued from Wyoming’s post 1976 Compact allocation were:

STREAM GAGING

As was indicated in the "Overview" chapter of this report under the subsectionconcerning the "Stream Gaging Program" (see page O-14), the Bear River Commissionparticipates in a cooperative contract with the USGS for the maintenance of stream gages onthe Bear River and significant tributaries. Also, some of the states participate with the USGSin additional Bear River gages, as does PacifiCorp. The Commission believes the collectionof data concerning stream flows in the Bear River system is very important and allocates abouthalf of its annual budget in support of the cooperative stream gaging program with the U.S.Geological Survey. However, costs continue to increase and so the Commission is constantlyreviewing the stream gaging program to determine if all of the stations supported are necessaryfor the Commission to help the Commission fulfill the responsibilities assigned to it by theCompact. There were no changes to the Commission’s stream gaging program in 2004.

During 2004, a total of 31 gages were maintained on the Bear River system. Of these32 gages, 9 were part of a cooperative effort between the Bear River Commission and theUSGS. PacifiCorp maintained 15 gages on the Bear River system during 2004. The State ofUtah cooperated with the USGS for the maintenance of three stream gages in 2004, Idaho onegage, Evanston and Logan Cities each cooperated with the USGS in the maintenance of onegage and the USGS funded one gage. Figure 2004.15 shows a tabulation of these gages and theentities which participated in the operation and funding of each gage. The approximatelocations of the stream gages are shown on Figure O.5 in the Overview section of this report.

Publication of the streamflow records for 12 of the gages in this report were consideredto be of significant value to the Commission and are included as pages 04-34 through 04-45(Figure 2004.15).

(i') NAWQAsiteNote: Underlined station numbers indicate those gages for which stream flow data is published in this report.

I This gage is now maintained year-round. The Commission pays for approximately 8 months of gage maintenance and the USGS pays for theremaining 4 months, This gage is important to the USGS NAWQA efforts as its winter flows are correlated with the Bear River Below Smiths Forkgage,

2 Discharge measurements below Stewart Dam are required for interstate regulation pursuant to the Compact. However, flow is general only a fewcfs, PacifiCorp maintains this gage and reports discharge to the Idaho watermaster. The data are included with the Central Division's canal diversiondata herein.

Figure 2004.1504-33

3 This gage represents a summation of the Logan River discharge and canal diversions upstream of the gage (see gage 10108400). Gage 10109000 is partof the cooperative program with the USGS and the BRC, while gage 10108400 is maintained under a cooperative program between the USGS and the Stateof Utah, Of importance to the Commission, and published herein, is the combined flow of these two gages.
