Squaw Creek Diversion Dam Fish Passage Improvement Project. Squaw Creek, Little Salmon River Subbasin Central Idaho. Completion Report

摘要

The Squaw Creek diversion was a full passage barrier to Chinook salmon and a partial to full passage barrier to steelhead trout depending on stream flow. Adult steelhead were observed unable to climb the uppermost drop on the diversion dam. The concentration of steelhead trout at this location made them vulnerable to illegal fishing. In addition, this diversion did not have a fish screen or an adjustable headgate. Entrainment of juvenile steelhead trout into the canal occurred when the Squaw Creek diversion was operated.
