With an uptick in the run-size forecast for summer Chinook salmon, Columbia River fisheries managers this week extended angling in the river through the end of the month. Fishing in the lower river downstream of Bonneville Dam to the Astoria Megler Bridge in Astoria was set to end July 14, but the extension allows angling in that area to continue uninterrupted through July 31. Fall Chinook fishing begins the next day, Aug. 1.
