Fishery managers from Oregon and Washington announced that retention of adult Chinook will close effective Saturday and continue through July 31.  The effective area is the mainstem Columbia River from Bonneville Dam upstream to the Oregon/Washington border.  The action was approved after reviewing the latest run forecast, which biologists recently downgraded from 67,300 to 44,000 adult fish.  The two states previously closed adult Chinook retention in the lower Columbia downstream of Bonneville for the month of July.  The Columbia remains open to retention of sockeye salmon and hatchery steelhead, with a bag limit of two adult fish.  All sockeye are considered adults and must be recorded as adults on the combined angling tag.
