According to the Washington Department of Fish and Wildlife, anglers may keep coho salmon on the Columbia River from Priest Rapids Dam upstream to Rock Island Dam through October 15. The daily limit is six salmon with a minimum size of 12 inches. The limit may include no more than two adult Chinook and no more than four coho. Sockeye must be released. The department said returns of coho bound for the upper Columbia are large enough to meet conservation goals and still allow a sport harvest. It will monitor the fishery and may close it early if too many ESA-listed summer steelhead are caught and released. I have checked the dam counts and over 12,000 coho have passed over Priest Rapids Dam and available to anglers. A popular fishing area for coho is on the rip rap at Wanapum Dam. Returning coho will swarm in the area and can be reached by angler casting spinners or with a bobber and jig set up. I have observed anglers catching coho here and I tried it myself once without success, but it will make another attempt this season. I have not yet seen boats working the “toilet bowl” below the dam.
