It's a scary lake to navigate indeed. It can go from 100' deep to 4' deep in as little as 20' distance. Really have to be careful, but it is quite well marked. Just make sure you know how to read the markers and have a good compass at the helm. If I were fishing there I would focus on smallmouth for sure. For one, you'll have to troll deep this time of year and that increases your risk of snagging bottom. Two, I have trolled that lake pretty extensively and never found a laker on the end of my line. Now someone else may say different, but I feel it's just not a great trout fishery. May be just my experience. On the flip side, the smallmouth fishing there is fantastic! In my opinion one of the best smallmouth waters we have in the state.
You might want to post this in the regional board, it may get more action there.
