Middle Snake River water quality for Kanaka and Boulder Rapids. Final report

This report covers water quality data collected by the University of Idaho at Kanaka and Boulder Rapids located in the Middle Snake River. The Middle Snake River flows through an incised canyon from Milner Dam to King Hill. The present location and configuration of the river is the result of ancient canyon filling processes and erosion and sedimentation during the Pleistocene Bonneville flood (Malde, 1968). Kanaka and Boulder Rapids of the Middle Snake River are located approximately in the middle of the reach, north and northeast of Buhl, Idaho at river miles 592 and 597. Upstream of the rapids the Snake Plain aquifer partially discharges into the river at Crystal Springs and Nigera Springs. The purpose of the water quality study was to document the water quality of the Middle Snake River at the rapids prior to development of several run-of-the-river hydropower facilities by L. B. Industries. Submitted to L .B. Industries
