WATER QUALITY OF BELTON LAKE, CENTRAL TEXAS

By H. B. Mendieta and Dale L. Pate

ABSTRACT

The concentrations of dissolved solids, chloride, and sulfate in Belton Lake on the Leon River in central Texas average about 240 milligrams per liter, 40 milligrams per liter, and 30 milligrams per liter, respectively. The water is hard or very hard, averaging 170 milligrams per liter as calcium carbonate. The average concentrations of these constituents and hardness are least during late summer and early fall after periods of sustained high inflow.

Thermal stratification begins to develop in Belton Lake in late February or early March. The water usually is stratified into three fairly distinct layers by early June, and stratification usually persists until September or October. Thermal stratification and seasonal variations in the concentrations of dissolved constituents in inflow result in stratification of the principal dissolved constituents. Dissolved solids in water at the surface of deep sites during summer differ from those at the bottom by about 40 milligrams per liter. Thermal stratification also results in significant seasonal and areal variations in dissolved oxygen, dissolved iron, dissolved manganese, total inorganic nitro gen, and total phosphorus.

Oxygen used in the oxidation of dead organisms and other organic material near the bottom of the lake is not replaced during periods of summer stagna tion. Consequently, water below depths of 35 to 40 feet (10.7 to 12.? meters) usually contains less than 1.0 milligram per liter of dissolved oxygen during these periods.

Water near the surface at most sites in the lake throughout the year usually contains less than 30 micrograms per liter of dissolved iron and 20 micrograms per liter of dissolved manganese. Reducing conditions during peri ods of summer stagnation result in the dissolution of iron and manganese from the sediments in deep areas of the lake. The concentrations of both constit uents are greatest near the bottom at site AC, a deep site near Belton Dam. Iron concentrations at this site during the summer have ranged from 0 to 600 micrograms per liter and have averaged about 290 micrograms per liter; manga nese concentrations have ranged from 0 to 540 micrograms per liter and have averaged about 320 micrograms per liter.

Concentrations of total inorganic nitrogen and total phosphorus are great est at deep sites during periods of summer stagnation when decay of aquatic organisms and chemical reduction of bottom sediments release the constituents to the water. The concentrations of total inorganic nitrogen and total phos phorus in the bottom stratum of water at site AC during the summer average about 0.75 milligram per liter of nitrogen and 0.10 milligram per liter of phosphorus. The concentrations of these constituents in the surface stratum at site AQ during the summer average about 0.02 milligram per liter of nitrogen and 0.01 milligram per liter of phosphorus.

The maximum concentrations of chlorinated hydrocarbon insecticides or their degradation products detected in bottom sediments collected from the lake during four lake surveys included 1.1 micrograms per kilogram of DOT, 3.0 micrograms per kilogram of ODD, 11 micrograms per kilogram of DDE, and 2 micrograms per kilogram of chlordane.

INTRODUCTION Purpose of This Study

The purpose of this report is to summarize the water-quality records of Belton Lake and to explain the variations of selected water-quality constitu ents and properties from September 1970 to August 1976. Other reports contain ing the results of water-quality surveys for Belton Lake are given in the list of references.

The U.S. Geological Survey has made comprehensive water-quality surveys of selected lakes and reservoirs in Texas periodically since October 1961 as part of a continuing cooperative program with State, Federal, and local agencies to inventory the surface-water resources of Texas. The program was initiated with a survey of Belton Lake on October ?5, 1961, in cooperation with the Texas Department of Water Resources, the Brazos River Authority, and the U.S. Army Corps of Engineers.

The purposes of the initial reservoir studies were to determine seasonal variations in water temperature and salinity and to define temperature and salinity-induced stratification patterns. During these initial surveys, spe cific conductance and temperature were measured at a number of selected sites near the water surface, near the bottom of the lake, and at several intermediate depths. The results of these measurements were used as guides in the collection of water samples for laboratory determinations of dissolved chloride and dis solved solids.

Regression curves for specific conductance and chloride and specific con ductance and dissolved solids were developed to determine the salinity of water throughout the reservoir. No significant salinity or salinity-induced stratifi cation problems were noted for Belton Lake, and the surveys were discontinued in 1964. The results of these initial surveys were summarized by Mendieta and Blakey (1963) and by Leifeste and Popkin (1968).

More comprehensive seasonal water-quality surveys of Belton Lake were begun in September 1970 and are continuing. The specific conductance, tempera ture, pH, and dissolved-oxygen concentration of the water at a number of selected sites are determined near the water surface, lake bottom, and at several inter mediate depths. The results of these determinations are used as guides in the collection of water samples for laboratory analyses of selected dissolved con stituents and properties, including silica, calcium, magnesium, sodium, potas sium, bicarbonate, carbonate, sulfate, chloride, iron, manganese, fluoride, dissolved solids (sum of constituents), total hardness, and noncarbonate hard ness. The analyses also include selected nutrients, including total phosphorus and total ammonia, nitrite, and nitrate nitrogen.

Description of Belton Lake and Its Environment

Belton Dam is on the Leon River in Bell County about 3.5 miles (5.6 km) north of Belton, near the geographic center of Texas. Most of Belton Lake is in Bell County, but small headwater tributaries to the lake extend into Coryell County (fig. 1). The lake consists of a compact main body downstream from the confluence of the Leon River and Cowhouse Creek and two main arms that extend along the drowned channels of the two streams.

The lake is on the eastern edge of the Edwards Plateau among a series of steep scenic limestone hills covered with juniper and small oak. The rugged topography near the lake gradually changes to rolling, rocky hills with hori zontal beds of Cretaceous limestone in the central part of the drainage basin. The area is mostly rural; cattle, sheep, and goats graze in the more rugged terrain, and small grain crops and pecan or fruit trees grow in the valleys. The sandy soils of the headwater's part of the drainage basin are more suitable for diversified agriculture, such as the production of peanuts, corn, small grains, cotton, melons, and fruit. Several oil and gas fields also are located in the headwater's part of the drainage basin.

Bel ton Lake, which was constructed and is operated by the Army Corps of Engineers, was designed for flood control and conservation storage. Construc tion of Eel ton Dam was begun in July 1949 and completed in December 1954. Deliberate impoundment of water began in March 1954. The capacity at the top of the original conservation-storage pool, which was set at 569.0 feet (173.4 m) NGVD of 1929, was 210,600 acre-feet (2.60 x 108 m3 ). Normal conservation capacity was achieved for the first time in l^ay 1956.

In July 1964, the Brazos River Authority received permission to impound an additional 247,000 acre-feet (3.05 x 10** m3) of water for municipal supply, industrial use, and irrigation. The top of the conservation pool was raised to 594.0 feet (181.1 m) NGVD of 1929, which gives the lake a surface area of 12,300 acres (4.98 x 10 7 m 2 ) and a storage capacity of 457,600 acre-feet (5.64 x 108 iir). Normal conservation capacity for this elevation was first achieved in May 1973. Other data regarding the dam and lake, compiled by Dowel! and Petty (1973, p. 12-24.0-A), are given in the following table:

ANALYSIS OF WATER-QUALITY DATA Streamflow Records

Daily streamflow stations on the Leon River at Gatesville (station 08100500), about 79 river miles (127 km) upstream, and Cowhouse Creek near Pidcoke (station 08101000), about 38 river miles (61 km) upstream from Belton Dam, have been operated by the Geological Survey since October 1950. A daily streamflow station on the Leon River at Belton (station 08102500), 3.2 river miles (5.1 km) downstream from Belton Dam, has been in operation since 1923.

Records of the contents of Belton Lake and records of discharge for the Leon River at Gatesville (fig. 2), Cowhouse Creek at Pidcoke (fig. 3), and the Leon River at Belton (fig. 4) indicate that about two-thirds of the inflow to

the reservoir during the 1970-76 water years originated in the drainage area above the Gatesville and Pidcoke stations. Hater-quality data for these sta tions have not been collected; but data collected periodically from other sites upstream indicate that inflow to Belton Lake usually contains less than 300 mg/L (milligrams per liter) of dissolved solids, is moderately hard to very hard (61 mg/L to >180 mg/L as calcium carbonate), and is a calcium bicarbonate type water. Streamflow and water-quality data collected by the Geological Survey are published annually in the Geological Survey series, Water Resources Data for Texas.

Water Quality of Belton Lake Thermal Stratification

Impoundment of water in a lake or reservoir may result in significant changes in the quality of the water. Some of the changes may be beneficial; other changes may be detrimental. Many of the detrimental changes can be related to thermal stratification layering of the water due to temperature- induced density differences.

The following table (l< ! east, 1975, p. F-5) shows that pure water reaches its maximum density at a temperature of about 4°C (Celsius) and that the dif ference in density per 1°C is much greater at warmer temperatures than at cooler temperatures.

For example, a change in temperature from 29° to 30°C results in a change in density of about 0.0003 g/mL (gram per milliliter); whereas a change in temperature from 10° to 11°C results in a density change of about 0.0001 g/mL. Stable stratification is common in lakes and reservoirs where the density of the upper and lower strata of water differs by as little as 0.001 to 0.002 g/mL. Thus, temperature differences of 3° to 4°C during the summer may result in stable stratification.

Thermal stratification may assume many patterns, depending upon the geo graphical location, climatological conditions, depth, surface area, and config uration of the lake or reservoir. During the winter, many deep lakes or reser voirs in the temperate zone are characteristically isothermal--that is, the water has a uniform temperature and density and circulates freely. Hith the onset of spring, solar heating warms the incoming water and the water at the lake or reservoir surface causing a decrease in density. This warm surface water floats on the colder and denser water. As the surface water becomes

progressively warmer, the density gradient increases and the depth to which wind can mix the water is diminished. Thus, water in the lake or reservoir commonly is separated into three fairly distinct strata:

(1) The epilinnion--a warm, freely circulating surface stratum,(2) the metalimnion a middle stratum characterized by a rapid decrease

in temperature with increases in depth, and(3) the hypolinnion--a cold, stagnant lower stratum.

Thermal stratification in deep lakes or reservoirs usually persists until fall, when a decrease in atmospheric temperature cools both the surface water in the reservoir and inflow from streams. When the temperatures and densities of the epilimnion and metalimnion approach those of the hypolimnion, the resis tance to mixing is reduced, and complete mixing or overturn of the water occurs.

Most of Bel ton Lake is deep and narrow and is within steep canyon walls. Depths throughout most of the main body of the lake and along the drowned chan nels of the Leon River and Cowhouse Creek exceed 50 feet (15 m). The pattern of thermal stratification in these deep areas usually conforms to the classical three-layered pattern.

Water-temperature data for the lake during water-quality surveys are shown in tables 1-19 and in figure 5. These data, supplemented by air-temperature data for the station at Beltcn Dam (fig. 5), indicate that the fall overturn usually begins in September or October and that the water in the deep areas of the lake is nearly isothermal from mid-November through mid-February. Warming of the surface water usually begins in late February or early March, continues during March, April, and Hay, and results in a gradual vertical temperature gradient. The temperature gradient usually steepens during June, July, and August and results in three fairly distinct layers in deep areas of the lake.

This seasonal pattern of warming and cooling of water in Bel ton Lake is occasionally interrupted by local weather conditions. The winters usually are mild; air temperatures (and thus water temperatures) during the winter months seldom average less than 10°C. Intermittent periods of warm weather during the winters frequently cause corresponding increases in temperature of the inflowing water and water at the lake surface. The warm water creates local differences in the thermal profile. Local differences also occur when cold "northers" cool the inflow and surface temperatures of the lake.

Dissolved Oxygen

Fish and other aquatic organisms require oxygen to maintain the metabolic processes that produce energy for egg and larvae development and normal activ ities. Moreover, some of the chemical constituents dissolved in water are related to dissolved-oxygen concentrations; therefore, dissolved oxygen is one of the most important factors that affect the quality of water in a lake reservoi r.

Water entering a lake or reservoir contains organic material derived from both natural sources and from man's waste. Bacterial stabilization of this organic material requires oxygen. Decaying trees, brush, and other oxidizable material within the area inundated by a reservoir as well as decaying algae and other organic material produced within the reservoir exert an oxygen demand.

-10-

The distribution of dissolved oxygen in a lake or reservoir is related to thermal stratification. Oxygen enters the surface stratum by plant photosyn thesis and by absorption from the atmosphere. During the winter circulation, the water is exposed to the atmosphere repeatedly, and dissolved oxygen used in the decomposition of organic matter is replenished. However, during spring and summer, thermal stratification results in a reduction of vertical circula tion of the water. Oxygen used in the decomposition of organic material is not replaced in the hypolimnion, and a vertical dissolved-oxygen gradient develops.

Dissolved-oxygen data for Bel ton Lake are given in tables 1-22 and in fig ures 6 and 7. The data show that the concentration of dissolved oxygen in the lake varies seasonally and areally. The data also show that the dissol ved- oxygen gradient usually is steepest at deep sites during periods of summer stag nation when oxygen is depleted in the hypolimnion but is replenished in the epilimnion by atmospheric aeration and algal photosynthesis. During the win ter, as the vertical temperature gradient decreases and the water mixes, the concentration of oxygen increases progressively at the lower elevations until the water is well oxygenated throughout the lake. The pattern of dissolved- oxygen stratification frequently is variable during spring and fall because of intermittent periods of warming and cooling.

The depth-integrated concentration of dissolved oxygen at most sites in the downstream one-half of the lake averages about 3.0 mg/L during periods of summer stagnation and about 10.0 mg/L during periods of winter circulation. The concentration at most sites in the shallower headwaters of the lake aver ages more than 4.0 mg/L during the summer and more than 9.0 mg/L during the winter. Water below depths of 35 to 40 feet (10.7 to 12.2 m) usually contains less than 1.0 ng/L of dissolved oxygen during most of the summer.

Dissolved Iron and Manganese

The occurrence and distribution of dissolved iron and manganese in the waters of Belton Lake are related to the concentrations of dissolved oxygen. During summer stratification, the hypolimnion is unable to replenish dissolved oxygen used in the decomposition of organic material. During the period of anaerobic decomposition that follows, reducing conditions result in the leaching of iron and manganese from sediments at the bottom of the lake. The concentra tions of iron and manganese in the bottom waters at deep sites continue to increase throughout the duration of the summer stratification and eventually may reach several hundred yg/L (micrograms per liter) before the fall overturn (fig. 8). After circulation begins in the fall and oxygen is replenished in the hypolinnion, most of the iron and manganese is oxidized to less soluble forms and settles to the bottom of the lake.

Water near the surface of the lake throughout the year and water near the bottom during periods of winter circulation usually contain less than 30 yg/L dissolved iron and less than 10 yg/L dissolved manganese. During periods of summer stagnation, the concentrations of both constituents in water near the bottom of the lake increase in the downstream direction in response to increases in depth and decreases in the concentration of dissolved oxygen (figs. 9 and 10).

The iron concentrations near the bottom at site IQ , a shallow site in the headwaters of the Leon River arm of the lake, have ranged from 0 to 630 yg/L during the summer and have averaged about 180 yg/L. Manganese concentrations at this site have ranged from 10 to 360 yg/L and have averaged about 140 yg/L.

At site AC, a deep site near Bel ton Dam, the concentrations of iron in v/ater near the bottom have ranged from 0 to 600 yg/L during the summer and have averaged about 290 yg/L. The concentrations of manganese at this site have ranged from 0 to 5^0 yg/L and have averaged about 320 yg/L. The concentra tions of both constituents at deep sites during summer stagnation increased after August 1971 as the depth and surface area of the lake increased in response to increasing the conservation-storage capacity (fig. 11).

Total Nitrogen and Phosphorus

A literature review by Greeson (1971, p. 7) revealed that at least 21 elements in some chemical combination are essential nutrients in the biologi cal productivity in waters of a lake or reservoir. Among these nutrients, dominant roles in controlling productivity in most lakes and reservoirs are assigned to nitrogen and phosphorus because their concentrations in water are most likely to be the limiting supply.

Sources that may contribute nitrogen and phosphorus to a lake or reser voir include land drainage, sewage effluent, industrial waste, precipitation, decomposing plant and animal debris, and bottom sediment. Total nitrogen and total phosphorus in the inflow consist of four major components, dissolved and particulate inorganic forms and dissolved and particulate organic forms. As water enters the lake or reservoir, most of the particulate nitrogen and phos phorus settles to the bottom, but part of the dissolved fractions is used by algae and other aquatic organisms as primary sources of energy. Eventually, these organisms die, settle to the bottom of the lake or reservoir, and carry their cellular nitrogen and phosphorus with them.

During periods of summer stagnation, decay of both aquatic organisms and organic material in the bottom sediment reduces the concentration of dissolved oxygen and releases nitrogen and phosphorus to the hypolimnion where they remain until fall overturn. Nutrients in the inflowing water become incorporated in this seasonal cycle, resulting in increased nutrient concentrations available for release from bottom materials as the reservoir ages.

The concentrations of total inorganic nitrogen and total phosphorus (sum mation of total ammonia, nitrite, and nitrate nitrogen) in Bel ton Lake vary seasonally and areally. During periods of winter circulation, total inorganic nitrogen and total phosphorus concentrations usually are greatest in the head waters of the Leon River arm. of the lake and decrease progressively toward Bel ton Dam (figs. 12 and 13). During the winter, the concentrations of total inorganic nitrogen at site IQ near the head of the lake average less than 0.6 mg/L and the concentrations of total phosphorus average 0.06 mg/L. At site AC near Relton Dam, the nitrogen concentrations average less than 0.3 mg/L and the phosphorus concentrations average less than 0.03 mg/L during the winter.

The nitrogen and phosphorus concentrations in the water near the bottom at deep sites in Bel ton Lake usually are greatest during summer when the water is thermally stratified and the dissolved-oxygen concentrations are less (fig. 14). The concentrations of total inorganic nitrogen in the surface stratum at site AQ average about 0.02 mg/L during summer and 0.25 mg/L during winter. Concen trations in the bottom stratum average about 0.75 mg/L during summer and 0.23 mg/L during winter. Although the seasonal variation of phosphorus in water near the surface at these deep sites is usually insignificant, the assimilation by aquatic plants during the summer months reduces the inorganic nitrogen concentrations. The concentrations of total phosphorus in the surface stratum at site AQ average about 0.01 mg/L during both summer and winter. Concentra tions in the bottom stratum average about 0.10 mg/L during summer and 0.03 mg/L during winter.

At site HC, the average concentration of phosphorus at the bottom is the largest of all sites in winter (0.16 mg/L) and the smallest of any site in sum mer (0.06 mg/L. The concentrations of total inorganic nitrogen in the surface stratum at site IQ average about 0.05 mg/L during summer and 0.5 mg/L during winter. Concentrations in the bottom stratum average about 0.3 mg/L during summer and 0.6 mg/L during winter. The concentrations of total phosphorus in the surface stratum at site IQ average about 0.04 mg/L during both summer and winter. Concentrations in the bottom stratum average about 0.10 mg/L during summer and 0.06 mg/L during winter.

Although the concentrations of both total inorganic nitrogen and total phosphorus vary seasonally in Belton Lake, incorporation of the relatively small concentrations of these nutrients contributed by inflow into the seasonal cycle have not resulted in significant increases in the quantities of either nutrient in the lake (fig. 15).

The relatively small concentrations of nutrients indicate that the lake is oligotrophic, a term pertaining to waters in which primary biological pro duction is insignificant because concentrations of available nutrients are small. Therefore, the lake does not yet have a problem of aging through the buildup of plant and animal life.

Dissolved Solids, Chloride, Sulfate, and Hardness

Some of the more important properties or constituents that affect the util ity of a lake or reservoir as a source of public water-supply include dissolved solids, chloride, sulfate, and hardness. Because the concentrations of these properties or constituents and specific conductance of a water are directly related, onsite measurements of specific conductance can be used to estimate variations of these properties or constituents. Therefore, during each lake survey, the specific conductance of water at each data-collection site was determined at depth intervals of 5 to 10 feet (1.5 to 3 m). These data and results of analyses for dissolved solids, chloride, sulfate, and hardness for samples collected near the surface and bottom at selected sites (tables 1-22) were used to estimate average concentrations of the dissolved constituents during each of the lake surveys (fig. 16).

FIGURE 16.-Variations in average concentrations of dissolved solids, chloride, sulfate, and hardness, September 1970-August 1976

-25-

A significant decrease in the dissolved-solids concentration took place in 1971 and lasted for the remainder of the study. This change in concentration was caused largely by a corresponding decrease in the chloride concentration, a con stituent indicative of oil-field brine pollution. The chloride reduction fol lowed the order in 1969 by the Texas Railroad Commission prohibiting the storage of oil-field brines in surface pits.

Data in figure 16 show that water in Belton Lake usually is hard (121 to 180 mg/L as calcium carbonate) or very hard (greater than 180 mg/L as calcium carbonate). The hardness averages about 170 mg/L. The concentrations of dis solved solids average 240 mg/L, chloride about 40 mg/L, and sulfate about 30 mg/L.

A comparison of data in figure 16 with streamflow data in figures ?. and 3 shows that seasonal variations in the concentrations of dissolved solids, chlo ride, and sulfate in the lake occur in response to variations in the quantity of inflow. The average concentrations of these constituents and hardness are usually least during late summer and early fall after periods of sustained high inflow.

The seasonal variations in concentrations of dissolved constituents in inflow has resulted in stratification of the principal dissolved constituents within the lake. Stratification of dissolved constituents usually is maximum at deep sites in the downstream one-half of the lake during summer (fig. 17). Data show that the average concentrations of dissolved solids in water at the surface of these sites during summer differ from those at the bottom by about 40 mg/L. The average concentration of dissolved solids for each individual survey usually varied less than 10 percent from the average computed for the entire period.

Water Transparency

Aquatic plants require light for photosynthesis. The principal factors that affect the depth of light penetration in a lake include color and turbidity. Turbidity is a function of both the concentration and size of suspended parti cles. The suspended material may consist of mineral particles (suspended sediment) from inflowing streams and living or dead microscopic plants and animals or their detritus.

V!ater transparency in Belton Lake, as determined by Secchi-disk readings, usually is considerably less at headwater sites DQ on the Cowhouse Creek arm and Ir on the Leon River arm than at site AQ near Belton Darn (tables 5-19). Secchi-disk readings average less than 3.0 feet (0.9 m) at site IQ (9 readings), less than 6.0 feet (1.8 m) at site DQ (13 readings), and more than 9.0 feet (2.7 m) at site AQ (15 readings). The increase in transparencies as the water moves downstream in the lake indicates that a significant part of the suspended material in inflow settles to the bottom in headwater areas of the 1 ake.

Pesticide Residues in Bottom Sediments

The tern "pesticide" encompasses a class of toxicants used to control insects, mites, fungi, weeds, aquatic plants, and undesirable animals. More specific designations include such terms as insecticide, miticide, fungicide, herbicide, and rodenticide.

The chlorinated hydrocarbon insecticides, a group of synthetic compounds that are very effective in controlling animal pests, came into use about 40 years ago and reached their maximum usage during the 1960's. Most of these compounds are metabolic analogs, protein denaturants, or enzyme inhibitors that tend to persist in the environment because of their slow degradation rate. Some of the degradation products also maintain pesticide properties. Consequently, their continued effect on the environment and ecological balance is a matter of national concern.

The use of chlorinated hydrocarbon pesticides in this country have now been either restricted or banned altogether, and their residues in the environ ment, including water bodies, have decreased. Most of these compounds or their degradation products are no longer detectable in waters of streams, lakes, or reservoirs. Nevertheless, numerous studies have shown that the chlorinated- hydrocarbons residues are still found adhered to fine sediment on the bottom of lakes and streams.

Studies continue throughout the world to determine the concentrations of these pesticide residues in the environment and to assess their effect on plant and animal life. Of special concern is the uptake and concentration of pesti cides by organisms in the food chain.

Four composite samples of bottom sediments collected from sites AC, DQ , HQ, and IQ in Bel ton Lake during the August or September surveys from 1973 to 1976 were analyzed for residues of the most common chlorinated hydrocarbon insec ticides or their degradation products and PCB (polychlorinated biphenyl) com pounds. RGB's are a group of industrial compounds that also have adverse effects on the environment. The bottom-sediment samples were analyzed for aldrin, ODD, DDE, DOT, dieldrin, endrin, heptachlor, heptachlor epoxide, lindane, chlordane, toxaphene, and PCB (tables 10, 13, 16, and 19).

Either DDT, its homolog DDD, or its decay product DDE was found in each of the four samples. DDT was detected in only one sample at a concentration of 1.1 yg/kg (micrograms per kilogram). DDD was detected in three of the four sam ples at concentrations ranging from 0.0 to 3.0 pg/kg. DDE, which has no insecti- cidal activity, was detected in all four samples at concentrations ranging from 5.1 to 11 yg/kg.

Chlordane was detected in one sample at a concentration of 2 yg/kg. No other pesticides or PCB compounds were detected.

SUMMARY OF CONCLUSIONS

Thermal stratification in Belton Lake usually begins to develop in late February or early March. Intermittent periods of warm and cool weather during late winter and early spring frequently cause thermal stratification to be unstable. However, by early June, the water usually is stratified into three fairly distinct layers: (1) The epilimnion, a warm, freely circulating sur face stratum, (2) the metalimnion, a middle stratum characterized by a rapid decrease in temperature with an increase in depth, and (3) the hypolimnion, a cold, stagnant lower stratum. The temperature gradient usually increases dur ing the summer and the layers become more distinct. Thermal stratification usually persists until September or October when the fall overturn begins. The depth to which water is mixed or circulated continues to increase as the water cools until water throughout most of the reservoir is nearly isothermal.

The concentration and distribution of dissolved oxygen in Belton Lake is related to the pattern of thermal stratification. Dissolved iron and manganese and total inorganic nitrogen and phosphorus are in turn dependent on the concen tration and distribution of dissolved oxygen.

The depth-integrated concentration of dissolved oxygen at most sites in the downstream one-half of the lake averages about 3.0 mg/L during periods of summer stagnation and about 10.0 mg/L during periods of winter circulation. The concentration at most sites in the headwaters of the lake averages more than 4.0 mg/L during the summer and more than 9.0 mg/L during the winter. Water below depths of 35 to 40 feet (10.7 to 12.2 m) throughout the lake usu ally contains less than 1.0 mg/L of dissolved oxygen during most of the summer.

Water near the surface at most sites in the lake throughout the year usu ally contains less than 30 pg/L of dissolved iron and 20 yg/L of dissolved man ganese. The concentrations of both constituents in water near the bottom at deep sites increase during periods of summer stagnation and usually are greatest at site AC near Belton Dam. Iron concentrations in water near the bottom of site AC during summer have ranged from 0 to 600 u9/L and have averaged about 290 ug/L. The concentrations of manganese at this site have ranged from 0 to 540 ug/L and have averaged about 320 ug/L. The concentrations of both constit uents at deep sites during summer stagnation increased after August 1971 as the depth and surface area of the lake increased in response to increasing the conservation-storage capacity.

The nitrogen and phosphorus concentrations in water near the bottom at deep sites near Belton Dam are usually greatest during periods of summer stagna tion when the decay of aquatic organisms and chemical reduction of bottom sedi ments reduce the concentration of dissolved oxygen releasing nutrients to the water. The concentrations of total inorganic nitrogen and total phosphorus in the bottom stratum of water at site AQ during the summer average about 0.75 mg/L of nitrogen and 0.10 mg/L of phosphorus. Total inorganic nitrogen and total phosphorus concentrations in the surface stratum during the summer at site Ac average about 0.02 mg/L nitrogen and 0.01 mg/L phosphorus.

The concentrations of dissolved solids, chloride, and sulfate in Belton Lake vary seasonally in response to variations in the quantity of inflow and usually are least during late summer and early fall after periods of sustained

-29-

inflow. The average concentration of dissolved solids in water at the surface of these sites during summer differ from those at the bottom by about 40 mg/L.

A significant decrease in the dissolved-sol ids concentration occurred in 1971 and lasted for the remainder of the study. This change in concentration was caused largely by a corresponding decrease in the chloride concentration, a constituent indicative of oil-field brine pollution.

The water in Bel ton Lake usually is hard or very hard, averaging about 170 mg/L as calcium carbonate. The concentrations of dissolved solids average about 240 mg/L, chloride about 40 mg/L, and sulfate about 30 mg/L.

Water transparency in Belton Lake usually is considerably less at headwater sites than at sites near Belton Dam. Secchi-disk readings average more than 9.0 feet (2.7 m) at site AQ near Belton Dam, less than 6.0 feet (1.8 m) at site DQ on the Cowhouse Creek arm, and less than 3.0 feet (0.9 m) at site IQ near the headwaters of the Leon River arm.

Trace quantities of DDT, DDD, or DDE were detected in bottom-sediment of four composite samples collected from the lake. The maximum concentrations detected were 1.1 yg/kg of DDT, 3.0 yg/kg of DDD, and 11 yg/kg of DDE. Chlor- dane (2 yg/kg) was detected in one of the four samples. None of the other most commonly occurring chlorinated hydrocarbon insecticides or PCB compounds were detected.
