Abstract

Primary productivity studies were done on the Silver Bow-Clark Fork river system using algal assays to determine the eutrophication potential. EDTA additions were used to insure availability of trace-elements in the river waters. The Warm Springs ponds are effective in nutrient and metal removal. Phosphorus is limiting above the Warm Springs ponds and addition of sewage effluent could cause excessive algal growth. Further comprehensive chemical analysis was found necessary before complete evaluation of the eutrophication potential may be considered.
