Comparative chemistry of a cooling reservoir and its water source
To better understand limnological processes in southern reservoirs receiving heated effluents, water was analyzed before and after impoundment in 330-ha North Lake. Macronutrients and metals were quantified within the water column and in the sediments during this 2-year study. Reservoir source water from Elm Fork, Trinity River contained 16 times more total phosphorus and supported 23 times more Selenastrum capricornutum cells in an algal assay than did water from the impoundment. The reservoir has essentially no drainage and since evaporation is high, the concentrations of many dissolved solids have increased three- to sevenfold since the reservoir was first filled in 1958. North Lake is presently phosphorus-limited, based on algal assay and chemical data. Apparently altered chemical equilibria have caused adsorption or precipitation of phosphorus with calcium and iron.
