|
Standard Water Quality Monitoring |
|
|
Daily Tailwater Temperatures |
Tailwater temperatures are taken daily for comparison to state quidelines for downstream water temperatures. |
|
Water Chemistry/Dissolved Oxygen/Temperature/Turbidity |
Chemical and physical water quality data are collected at inflow and tailwater stations 4 times per year during thermal stratification. Chemical and physical data are collected at the damsite station 1 time per year during thermal stratification. Temperature and dissolved oxygen profile data are collected at the damsite on a bi-weekly basis beginning in mid-May and continuing until thermal destratification and complete mixing of the water column in fall. Structural limitations do not allow for significant adjustment of reservoir water release elevations to regulate downstream water temperature; however, the data provide for ready evaluation of general water quality conditions in the reservoir, and are used for other water quality studies. |
|
Biological Parameters |
Phytoplankton and chlorophyll a samples are collected from each lake station 1 time per year during thermal stratification.
Macroinvertebrate samples are collected from inflow and tailwater stations 1 time per year in the fall. |
|
Sediments |
Sediment samples are collected for priority pollutant analysis from each lake station on a 5-year rotational basis. Sediment samples were last collected in Cagles Mill Lake in 1998 and 1999. |
