Thermal Effects on Primary Productivity of Phytoplankton, Periphyton and Macrophytes in Lake Keowee, South Carolina

摘要

Productivity of phytoplankton, periphyton and macrophytes at three stations in Lake Keowee was measured from April, 1973 to April, 1975. Average monthly productivity for phytoplankton was 1097.19, 1037.33 and 880.54 mg sq cm/month m0-1 at Station 1.2, and 3 respectively. Both low nutrient concentrations and low productivity classifies Lake Keowee as an oligitrophic lake. This investigation could demonstrate no significant effect of thermally elevated reactor cooling effluents on the productivity of phytoplankton or periphyton.
