Proportion of Chinook redds protected from dewatering



SPU and the Cedar River Instream Flow Commission have been monitoring Chinook salmon redds (nests) in the Cedar River since 1999. To help provide beneficial conditions for incubating eggs and larval fish (“alevins”), fall and winter stream flows should remain above levels that would allow the redds to become “dewatered”. Since the program began, stream flows have remained at levels that have ensured virtually all Chinook redds in the river were protected from dewatering.
