UPPER SNAKE BASIN, IDAHO WATER QUALITY MONITORING ASSESSMENT REPORT, PHASE I. 1971
Description:
The Upper Snake River Basin, Idaho (17040104, 170402) was studied in an effort to establish a monitoring network from above Idaho Falls to Milner Dam. The object was to provide timely data and information pertaining to the priority problems of the basin and to be responsive to the needs of the Regions divisions and programs. To accomplish this, monitoring activities must be geared to the priority problems in the basin which are defined in the development of the regional pollution profile. The profile is composed of the Water Quality Index (WQI) and the Pollutant Source Index (PSI). The PSI for the Upper Snake shows the relative problem severity as: DO, 103; aesthetics, 22; bacteria, 12; temperature, 1; toxicity, 0; and turbidity, 0. One objective of the monitoring program will be to more clearly define the role that these factors play in the water quality profile of the Upper Snake Basin. A number of receiving water locations, in addition to municipal and industrial effluents and groundwater stations, are proposed for study. Water quality simulation by mathematical modeling is being used as a tool in the design of the monitoring program.
