Interim Downstream Fish Passage
Cle Elum, WA
A temporary wood flume in an existing spillway was constructed. In addition, new concrete piers were constructed at the entrance to the wood flume to direct water from the lake through the flume. The project was designed to study the migration of salmon downstream from the upper lake to the flowing river below.
