Significant progress was attained in implementing the complex and challenging studies of wild steelhead Oncorhynchus mykiss production in Idaho. Study sites were selected and techniques were developed to collect the needed data in remote wilderness locations. Cursory examination of existing data provides indication that most wild steelhead stocks are under escaped, especially the Group B stocks. Abundance of wild steelhead is generally declining in recent years. The portable weir concept and electronic fish counting developed through this project have been well received by land owners and reviewing governmental agencies with less impact to the land, stream, and fishery resources than conventional permanent weirs.
