I used to fish there a lot when I was at UT. We fished under the dam. There was always water flow, caught a lot of striper there. We waded, if i went there now I'd take a kayak, fish it all from the dam down- good water.
This was a really nice article in SW Fly fishing last year. You can download it for a fee. Lots of good info about how to fish the lake, and where to launch and where to eat. Highly recommended.
Here is a link to a map of the lake. I don't know how much help it will be, but it is a topo of the actual lakes so you might be able to gather some good info off of it.
