The steelhead fishing along the Upper Columbia River and its tributaries above Rock Island Dam will end one hour after sunset on Monday, March 31.
State Fish and Wildlife has determined that most steelhead will be spawning beginning next month, and the National Marine Fisheries Service allows a fishery to be open only through March 31.
This includes the following areas:
Columbia River from Rock Island Dam to 400 feet below Chief Joseph Dam.
Wenatchee River from the mouth to 400 feet below Tumwater Dam, including the Icicle River from the mouth to 500 feet downstream of the Leavenworth Fish Hatchery Barrier Dam.
Methow River from the mouth to the confluence with the Chewuch River in Winthrop.
Okanogan River from the mouth to the Highway 97 Bridge in Oroville.
Similkameen River from the mouth to 400 feet below Enloe Dam.
