Coho salmon caught from the Astoria-Megler Bridge 300 miles upstream to where the Columbia River crosses the Oregon-Washington border must be released, according to the Washington Department of Fish and Wildlife.
The new rule will expire Aug. 1 when the fall fishing season begins.
Coho salmon started arriving in the Columbia River in July, which was not expected. Current drought conditions are an unlikely cause of thier early arrival, said Ron Roher of the department. Warm temperatures typically slow salmon migration.
“Then again, this isn’t a typical summer for fish management,” he said.
