Temperature, Dissolved Oxygen, pH, and ORP Depth Profile
The Reservoir met the aquatic life standards for temperature, dissolved oxygen and pH in 2019.
The Reservoir met the temperature standards established for the Class I Warm Water Aquatic Life classification established by the Water Quality Control Commission (WQCC) in Regulation No. 31 (REG 31) of 26.2 ˚C Maximum Weekly Average Temperature (MWAT) and 29.3 ˚C Daily Maximum (DM).
Dissolved oxygen (DO) concentrations met the standard of 5.0 mg/L throughout WY 2019 in the top layers of the reservoir. Under the standards, the DO may be less than 5.0 mg/L near the bottom as long as there is refuge with DO levels greater than 5.0 mg/L available for aquatic life. A few times levels from 4m to the bottom were less than 5.0 mg/L; however, during those times, the majority of the reservoir had DO levels that exceeded 5.0 mg/L providing adequate habitat (refuge) for aquatic life. Periods of low dissolved oxygen indicate high microbial activity or decomposition in the sediments which reduces DO concentrations.
During WY 2019, the pH ranged between 7.7 and 8.6, which meets instantaneous minimum and maximum standards of 6.5 and 9.0, respectively. The higher pH values appeared to correlate with higher productivity and elevated chlorophyll α in the reservoir.
