Smokey Valley is a small lake, and not really clear imo. It used to be a "trophy" lake managed by KDFWR, so there are a few nice bass in there. Most of the ones I have caught there tend to be 10 - 14 inches. There have been reports of a few 5 - 6 lb bass caught in recent years. It gets a lot of pressure from catfishermen. The "ramp" is a very small unimproved one, johnboat or 2 man bass hunter recommended.
I also like to bluegill fish there, especially with a light fly rod.
