Although I have never been in there, I do know the lake was almost drained recently, and a year or two ago, 6 boats and fishing teams hit the lak at least 2 weekends catching over 600 fish a day (each?) for transfer to Skinner and Diamond valley lake. When the contractor replacing the pumps drained the lake, they got a good look and reported not a hell of a lot there, mostly because of the bluestoning. i am a contractor myself, and with some of the activity out there I suspect they are installing a decent security system so BE CAREFUL....
