NOT planning on Salmon fishing from the tube, holy crap, seems nuts.
If you can get your hands on a copy of "Lake Fly Fishing Guide by Jim Bradbury and Beverly Miller you'll have it made. It will give you directions, how to fish and which flies to use for many lake right in the area you asked about. Badger Lake, Barnes Butte Lake, Clear Lake, Frog Lake, Harriet Lake, Jean Lake, Laurence Lake, Olallie Lake, Pine Hollow Reservoir, Rock Creek Reservoir, Round Lake, Trillium Lake , Timothy Lake and many more. It comes from Frank Amato Publishing and is full of information on these lakes and fly fishing from a float tube. You might be able to find it online or at the library. I bought my copy about 21 years ago and still refer to it. Good luck
