try casting spoons in deep slow eddies and swirls around the hatchery by chief hole, sandy bottom or the hatchery there is a good chance of hooking some coho in there about now,., you can pick up nice steel head using roe, night-crawlers and a corkie, yarnies or jigs.,.,, there is a substantial number of fish between shady cove and the hatchery so all through that area have produces large amounts of fish for us,., as for chasing large coho try "jigging" spoons in chief hole in the slow water there ,it is about 10-15 feet deep in that hole with moss and sandy holes on the bottom so there are coho schooled up in there ya just need to get them out
good luck ,., any thing else ya want to know ?
