BOISE RIVER STUDY IN ADA COUNTY IDAHO, 1978
Description:
The purpose of this study was to assess the impact of present point sources on the river and to obtain background information to develop effluent limitations for the City of Boise wastewater treatment facilities. The study was conducted on the Boise River (Ada County, ID) from Lucky Peak Dam to the Star Bridge (17050114). Monitoring occurred at 14 mainstem river stations at both Boise treatment plants on a monthly frequency. An intensive survey in November 1977 included three additional point sources and eight tributaries. Parameter categories covered in this study are: temperature, DO, pH, flow, bacteria, oxygen demand, solids, nutrients, trace inorganic toxins, macroinvertebrates, periphyton, and algal assays. Water quality of the Boise River in Ada County was found to fluctuate with seasonal conditions. During non-irrigation season, the water quality problems were generally worse except for bacteria. Toxicity problems (ammonia, chlorine, iron, aluminum, and fluoride) were more evident during the non-irrigation season. Water Quality Summary No. 2. Department of Health and Welfare, Division of Environment, Boise, ID. October 1980.
