2008 Hydrometric Data Summary for Upper Chase Creek and Charcoal Creek

Prepared for Tolko Industries Ltd.

(Year 5 - 2008 Report) 1. Introduction: This report summarizes the hydrometric data collected during 2008 at the Upper Chase Creek and Charcoal Creek hydrometric stations. The stations are operated for Tolko Industries Ltd. and are funded by the Forest Investment Account (FIA). The hydrometric stations were established in 2004 to provide stream runoff data that could be used to determine if climate change and/or changes in forest cover due to the mountain pine beetle infestation are changing the timing and magnitude of annual peak flow events. The period of record for the stations varies from year to year depending on field conditions (ice conditions), however data is typically collected from May 1st through October 31st. 2. Project Activities: The 2008 project activities in are summarized in Table 1.

1 % Dep. refers to precipitation departure (%) from the normal/average value based on data from 1948-2008. The values are ranked from wettest to driest, and the ranks are adjusted to reflect only the study period, 2004-2008. The data in the above table is presented to compare year-to-year climatic conditions and the influence that those conditions may have on the annual hydrograph. The winter snowpack and spring precipitation both contribute to the annual peak flows. The wettest winter since this project started was in 2007 and the wettest spring was in 2006. The climate data is regionalized and may not account for localized precipitation conditions in the study watersheds. Continuous water level data (hourly data) was collected from April 1 to November 14, 2008 at the upper Chase Creek site and the Charcoal Creek site (refer to Appendix A - Data). Channel changes at Charcoal Creek were observed following the peak flow. The changes resulted in loss of low water level measurements, as the well was dry from July through October. Discharge during this period is estimated using comparative/relative values in the adjacent Upper Chase Creek watershed. Five discharge measurements were completed during 2008 to create/confirm the stage discharge curves for both sites (refer to Table 3). The 2008 stage discharge curves for Upper Chase Creek remain unchanged since 2007. The curves remained unchanged at Charcoal Creek from 2007 until May 26, 2008. Following this date, anomalous water levels were recorded and are likely attributed to ice and sediment, which changed the channel shape. Discharge data could not be confirmed from May 26 to May 29, 2008. New stage discharge curves have been established for the period May 29 through June 30, 2009 but water level data beyond June 30 was not captured at Charcoal Creek. Due to the channel changes, the stilling well was dry after June 30. During the fall period, several man-made check dams were identified under the bridge near the station, which diverted water and re-wetted the stilling well. However, due to continuous man-made changes to the channel at this site during the fall period, it was not possible to create a stage discharge curve for the flows during this period. Charcoal Creek discharges during this period were estimated using the discharge values from Upper Chase Creek.


504-003/27077/March 2009 Page 3

The hydrographs at the two creeks respond similarly during the fall period, so the relative difference between the two streams flows from the 2007 fall period were used to “predict” the relative difference during the 2008 fall period (refer to Appendix A).

The data in this table was used to develop/confirm the stage discharge curves for each site. The mean monthly discharges were calculated using the hourly field data (water levels) and the corresponding discharge values derived from the stage-discharge curves (refer to Table 4 and Appendix A). The total monthly yield was calculated in cubic meters and converted to acre-feet (refer to Table 5). During April 2008, stream flows at Upper Chase Creek and Charcoal Creek were likely affected by ice dams, therefore this data may be subject to error. For annual comparison, only the May through October data is included.

For comparison purposes, the “total” values in Table 5 above only include values from May through October. To date, the maximum mean monthly discharges and monthly yields occurred in May 2008 at all three hydrometric stations. Because the fall of 2007 and winter and spring of 2008 were not the wettest during this study period, the reasons why the highest peak flows and water yields are recorded in 2008 is not attributed to climate conditions alone. The loss of mature pine due to the mountain pine beetle infestation and salvage harvesting may also be contributing to increased runoff and stream discharge, however additional years of data are required to better understand the water balance dynamics. The actual changes in forest cover and hydrological function in the watersheds are not addressed in this report. Upper Chase Creek The maximum daily discharge was 9.662 m3/s and occurred on May 18, 2008. The minimum daily discharge was 0.027 m3/s and occurred on September 19, 2008. The yield from upper Chase Creek (May 1 through October 31, 2008) was approximately 15,262 AF. Refer to Appendix A and Table 5 for additional details. The Chase Irrigation District has a license to divert runoff into Pillar Lake, however they did not divert water from upper Chase Creek during the 2008 open water period (the point of diversion is located immediately upstream from the hydrometric station).


504-003/27077/March 2009 Page 5

Charcoal Creek The maximum daily discharge was 5.682 m3/s and occurred on May 18, 2008. The minimum daily discharge, 0.082 m3/s occurred on September 20, 2008. The yield from Charcoal Creek (May 1 through October 31, 2008) was approximately 9,407 AF. A private dam and reservoir several kilometers upstream from the hydrometric station can affect the Charcoal Creek flows. There are three active water licenses at the reservoir for a total storage of 100 AF and 180 AF for irrigation and land improvements (~3% of total runoff). The channel changes following the 2008 peak flow allowed low flows to be diverted around the well, therefore these flows could not be detected. It is hoped that the conditions will naturally correct following the 2009 peak flow. The materials that shifted the stream and prevented the low flow measurements are gravel and small cobble sized and are likely to be transported downstream from the stilling well. If this is not the case, options must be undertaken to ensure the low flows can be measured. Regardless of the outcome, a new stage discharge curve will have to be established for Charcoal Creek. Water Survey of Canada Hydrometric Station - Chase Creek above the Mouth (Stn # 08LE112) This station records the runoff from the Upper Chase Creek and Charcoal Creek sub-basins as well as the run-off from the residual catchment areas. The maximum daily discharge (from May 1 to October 31, 2008) was 19.144 m3/s and occurred on May 18, 2008. The minimum daily discharge (0.067 m3/s) occurred on August 7, 2008. From May 1, 2008 to October 31, 2008 the total yield was approximately 31,777 AF. There is no detectable shift in the timing and magnitude of the annual peak flow events at the study locations since year one of the study, 2004 (refer to Table 6). Additional years of data are required to determine trends/changes to the annual hydrographs at the study sites.

4. Conclusions:

• The maximum daily discharge at upper Chase Creek was 9.662 m3/s and occurred on May 18th. The maximum daily discharge for Charcoal Creek occurred on May 18th and was 5.682 m3/s. The minimum daily discharge at upper Chase Creek was 0.027 m3/s and occurred on September 19, 2008 and the minimum daily discharge at Charcoal Creek occurred on September 20th and was 0.082 m3/s.

• The maximum daily discharge for WSC station 08LE112 Chase Creek above the

Mouth for the period May 1 to October 31 was 19.144 m3/s and occurred on May 18, 2008. The minimum daily discharge was 0.067 m3/s and occurred on August 7, 2008.

• For the period May 1 through October 31, the combined yield from upper Chase

Creek and Charcoal Creek was 24,669 AF. The water yield at the WSC station was 31,777 AF (7,108 AF or 29% more volume). The additional volume is from the residual watershed areas between the upper Chase/Charcoal stations and the WSC station. There are 37 active water licenses on Chase Creek, including the Chase Irrigation District’s license to store 500 AF in Pillar Lake. Although the Chase Irrigation District’s diversion was closed all season, the amounts and timing of the diversions from the other licenses is not known.

• No shift or change in the annual hydrograph is evident with the five years of

available data. Additional hydrometric, climate, and forest cover data will assist the understanding of the annual hydrographs in the study watersheds.

• The stage discharge curves for upper Chase Creek are unchanged since 2007.

The stage discharge curves for Charcoal Creek have changed and the current channel morphology and stilling well location do not allow for low flow measurements.


504-003/27077/March 2009 Page 7

5. Recommendations:

• The operation of the two gauging stations should continue through 2009. Understanding how the runoff characteristics for the these two sub-basins may be altered as a result of the ongoing changes to forest cover due to the mountain pine beetle can be used to help make better forest management decisions.

• Continue to measure stage and discharge and carry out routine inspections of

the sites during the 2009 open water season.

• Assess the channel morphology at Charcoal Creek following the peak flow period to determine if changes are required at the station to ensure low flow can be measured (ensure the stilling well will be wetted during low flows).

• If required, adjust the stilling well location and/or methods to measure

continuous water level data at this site. This may require using a different well and instrument configuration.
