Description:

The initial phase of this study involved compiling data to describe the current (1992) and historical aquatic biological conditions of surface water in the Snake River Basin (1704). To assess water quality of the basin, at least 26 different macroinvertebrate and fish community metrics have been utilized. Concentrations of synthetic organic compounds and trace-element contaminants in whole fish collected in the basin during 1970-90 generally did not exceed National Academy of Sciences and National Academy of Engineering concentration guidelines or the 1980-81 geometric mean concentrations from samples collected as part of the U.S. Fish and Wildlife Service National Contaminant Biomonitoring Program. The organochlorine compounds DDT and PCBs were the most frequently detected fish tissue contaminants. Arsenic, mercury, and selenium were slightly elevated compared with nationwide baseline concentrations and may indicated bioaccumulation in the food chain.

Title :WATER QUALITY ASSESSMENT OF THE UPPER SNAKE RIVER BASIN, IDAHO AND WESTERN WYOMING - SUMMARY OF AQUATIC BIOLOGICAL DATA FOR SURFACE WATER THROUGH 1992

Data Use & Constraints :Biological data in the upper Snake River Basin have been collected primarily by Federal, State, and academic organizations. Because of the diversity of the data reviewed, consolidation of the data for summary or comparison was difficult. Due to the lack of documentation on quality assurance and methods, the data were screened only for obvious errors and assessed qualitatively.
