If you want to catch a ton of trout, go to Depression Lake which is a small man made lake on the South East corner of Baker Lake. There is a earth dam that separates Depression from Baker. It is planted before the fouth of July weekend and should be full of trout when you get there. However, you will need a float tube. For your best luck, fish the deep water near the earth dam. Use woolly buggers and carey specials with a type II full sinking line. As far as steelhead goes, you can hit the Skagit, but you may just be getting a lot of casting practice in July.
