A monster run of coho totaling almost 1 million fish is forecast to return to the Columbia River this fall in addition to another huge surge of chinook.The specific fall chinook predictions are not yet out, but Washington and Oregon predict 964,100 adult coho salmon will be off the coast this summer destined to enter the Columbia River.In 2013, there were 316,900 Columbia River coho. “That number should provide opportunity at Buoy 10 with some coho in it,” said Steve Watrous of Vancouver, Washington sport fishing representative on the Salmon Advisory Subpanel of the Pacific Fishery Management Council. “We’ve not seen that in several years. There should be some pretty decent coho fishing this summer.”Year Coho2007 337,0002008 494,3002009 729,8002010 440,0002011 356,8002012 135,3002013 316,9002014* 964,100ForecastBuoy 10 is the name of the August-early September salmon season between Buoy No. 10 at the mouth of the Columbia River and a line 16 miles upstream stretching between Tongue Point in Oregon and Rocky Point in Washington.Once predominantly coho fishing on strong flood tides, Buoy 10 has largely become a chinook fishery upstream of the Astoria Bridge focused on soft ebb tides.
