I've never personally caught anything there and I fished it when I was in college. I know the big part of the lake is where you go to catch crappies and possibly perch and walleyes. The smaller part is where the trout are and they travel in a circle around the lake. The best time to catch the slimy ones is when they first dump them in, past that they don't feed as often. If you look on the IA DNR website they have a contour map on there now I believe.
