Fish Abundance Upstream from Dworshak Dam Following Exclusion of Steelhead Trout
Fish abundance was determined by underwater fish counts in selected locations on twelve tributary streams of the North Fork Clearwater River, Idaho. Fish numbers, species composition and fish density were compared to results from previous studies of the watershed to determine what changes have occurred in the fish populations fifteen years after anadromous fish were excluded from the watershed by the construction of Dworshak Dam.
