| Abstract: | ABSTRACT: Investigations were initiated to evaluate the effects of sedimentation on the algal composition, primary productivity rates and chemical nutrient concentrations of a 17 acre recreational impoundment in central Virginia. Comparisons during the winter seasons of 1972–1973 indicated that as a result of sedimentation, from lake front home construction, the total numbers of algal genera in the lake decreased from 24 to 16, productivity as measured by 14CO2 and total extractable chlorophyll decreased two fold, and several important nutrients, i.e. NH4+-N, SiO2 and PO4-P increased significantly. |
