Algae production and nutrient enrichment in Lake Coeur d'Alene, Idaho Item Info

In situ and in vitro (under controlled conditions of light and temperature) primary production rates using radioactive C-14 were measured over a 5-month period in Coeur d'Alene Lake. Distribution of phytoplankton and physicochemical parameters were assessed to distinguish broad area differences. These differences were used to aid in the explanation of variations in productivity throughout the lake. situ rates ranged from 0. 6-6.6 gC/m day at an enriched open water lake station, where a diatom-dominated phytoplankton community existed . In vitro rates ranged from 10-2250 mgC/m3/4-hr incubation period and indicated that the northern area of the lake was oligotrophic and the middle and southern areas were strongly mesotrophic. Concentrations of phosphate, nitrate, and alkalinity were likewise higher in the middle and southern portions of the lake, which supported the productivity measurements.
