If you are talking about Billy Chinook, I'd go up one of the 3 arms and jig with a small crippled herring or small buzz bom. You'll get some snagged fish, make sure you release them. You'll get planty of legitimate fish as well.
As for small mouths, they are nearly everywhere on that lake. Pull up to any point near shore, fish 10-15 feet from the bank with a small worm or jig, you'll catch 50 fish a day, 10 keepers.
