Some Aspects of the Summer Limnology of Lake Frierson

Physiochemical characteristics of Lake Frierson were monitored biweekly from 15 May to 14 September 1979. Lake Frierson revealed intense thermal stratification in late May. Stratification continued until fall turnover in mid-September. The anoxic hypolimnion started at the 3.0 to 3.5 m sampling depth and continued to the bottom. During this time, evaporation accounted for the loss of 1.0 m of water. Data from the shallow stations revealed anoxia and oxygen values of 2.0 mgll or less on 2 dates, 10 July and 8 August 1979.
