This report provides a synopsis for three years of inventory work on the streams in the Lower Clearwater Basin, Idaho. The main emphasis of the study was to document which streams presently support anadromous salmonids, the extent of production in those streams and the identification of those streams which may best respond to enhancement restoration activities. Rainbow-steelhead trout (Salmo gairdneri) were the most abundant anadromous salmonid found. Chinook salmon (Oncorhynchus tshawytscha) were found rarely except in the Lolo Creek Drainage. The main environmental problem affecting these streams was the extreme flow variations which commonly occur. This is due primarily to poor land management practices. Enhancement recommendations are suggested for these streams which include passage around barriers, barrier removal, riparian enhancement, instream habitat improvement, and better land use practices.
