I've fished it many times, but its dangerous. There are boat killers along the shore and weather gets nasty in a hurry with the wind whipping through those canyons. The boat launch is pretty sketchy too. I do think that the urban legends about that lake are probably slightly exaggerated.
The positive is there are massive silvers and browns in there. Caught a few smallmouth but nothing spectacular. I've had the best luck in November and December. I've limited out on 4-5lb silvers in an hour.
