Kootenai River Fisheries Investigation : Stock Status of Burbot : Project Progress Report 2008 Annual Report.
Objectives of this investigation were to (1) monitor the population status and recruitment of burbot Lota lota in the Kootenai River, Idaho and British Columbia, Canada during the winter of 2006-2007; (2) evaluate the selective withdrawal system in place at Libby Dam to maintain the river temperatur...
