Abstract
The purpose of this research project was to determine the effects of reducing by 90 percent the soluble inorganic phosphate input to Kootenay Lake, British Columbia, Canada, a significant link in the Columbia River system governed by United States-Canadian treaty. Measurements on temperature, transparency, inorganic and organic phosphate, nitrate, ammonium, chlorophyll a, copepods, and cladocerans were made during 1971-75, and compared with observations made for three years prior to phosphate reduction in 1969. Data indicate that primary production in the lake was nitrogen limited prior to 1969, phosphate limited two years later. These changes may also be related to the completion in 1972 of Libby Dam in Montana, upstream from the lake on the Kootenay River.
