Hi Steve, I don't have lots of experience but in the summer months I would go out in the deeper part of the lake where the water temps is more stable. I think most guys go out deep when kings bite slow down and fish for steelhead and coho in the first 20 to 50 feet of water. I would use spoons, spin doctor with fly in red or orange. When out deep look for temperature break and scum line. Hope this help. Good luck.
