We haven't been over to the lake since the weather turned so much colder, but the last time we fished it, we couldn't find any "keeper' walleyes. We caught many in the under 12 inch class, but nothing bigger. The fish we did find were hanging on sharp drop-offs on several different locations around the lake.
For what it's worth... my advice would be to drill lots of holes and rely on your depth finder to find some fish, then keep moving until you locate some of the larger year classes.
I want to find some of the perch and big crappies, but I haven't been able to, so we've been fishing some of the smaller ponds.
