From January to April, large numbers of Chinook salmon fry leave the Cedar River and rear in the south end of Lake Washington. These fish prefer non-armored shorelines with sand and gravel substrates that have both open beaches and areas with riparian vegetation which provide woody debris and overhanging vegetation. Unfortunately, the old flume has little of these habitat characteristics.

juvenile Chinook salmon in south Lake Washington
Chinook salmon are listed as threatened under the Endangered Species Act and resource managers in the Lake Washington area have been looking for shoreline areas that can be restored. The flume is an obvious choice because it is a large structure close to the Cedar River and is owned by Washington Department of Natural Resources (WDNR).
