The Oregon Department Fish and Wildlife is adopting additional emergency rules to increase protections for wild summer steelhead in certain Oregon Columbia River tributaries in response to extremely low returns of Columbia Basin upriver summer steelhead.  Passage counts of summer steelhead at Bonneville Dam from July 1 through August 26 are the lowest since counts began in 1938, continuing a pattern of several years of low returns for many populations and comes during a period when flows throughout the basin are generally low because of drought.  The rules will close steelhead fishing in the lower Umatilla and in additional areas of the Deschutes and John Day rivers beginning Wednesday.  That’s in addition to existing steelhead closures in portions of the lower Deschutes and John Day rivers, and on top of measures already taken in mainstem Columbia River fisheries to protect summer steelhead during their migration to the tributaries.
