If your talking Fish lake near Lake Wenetchee, you should catch a ton of fish. I was there on the 11th -12th and hammered the rainbows. We brought home 9 and released 25-30 in 2hrs on Thur. night and 2hrs Fri. morn. We did best trolling blue pirate f4 flatfish and perch,frog colored #70 hotshots. We caught 3 fish under 10" but the rest were 13-16". The far end of the lake was best but we caught em' everywhere. Just remember you can only keep 2 fish over 15" per person per day, and the state just planted all the bigger trout so they have white meat and don't taste nearly as good as the fish that have been in the lake a couple months. Have a great time bud!
