UPPER SNAKE RIVER BASIN WATER QUALITY STATUS, 1973
Description:
Historically, the Upper Snake River, Idaho from Milner Dam to the Idaho-Wyoming border (170402, 17040104) has experienced high bacteria concentrations and massive algal blooms. Algal blooms not only affect aesthetics, but also contribute to depressions of dissolved oxygen. The algal blooms result in part from high nutrient concentrations in the river. Studies by the EPA are continuing to determine the interrelationships between the water quality problems and to determine the cause-effect relationships between point and non-point sources of waste loading to the river and the river water quality. Intensive water quality studies were conducted by the EPA during October 1971, March 1972, and August 1972. The results of these surveys along with other Upper Snake River water quality data are discussed within this report. 1973. Environmental Protection Agency, Surveillance and Analysis Division. 90 pp.
