โฆ Synopsis
Hydrologic and total phosphorus budget data were obtained during a 24 month period for Spruce Knob Lake, Randolph County, West Virginia. Total phophorus retention was approximately 369,, of input for both years despite differences in flushing rate. Based on total phosphorus and hydrologic data, Spruce Knob Lake is eutrophic. Predicted spring total phosphorus concentrations from the DILLON-RIOLER nutrient budget model were in close agreement with actual observed concentrations. Application of literature models predicting total phosphorus retention based on flushing rate to Spruce Knob Lake data resulted in close agreement with actual retention values. Models based on hydraulic load were inadequate when applied to Spruce Knob Lake. Relative phosphorus residence time values (lake total phosphorus/inflow total phosphorus) for both years indicated t h a t the lake has a low sedimentation rate. Mass balance data confirmed this low rate of sedimentation.
