I have never flatlined anything in BL but it is a good way to fish. Something I forgot too comment on is the rocks in the lake. Be sure to read your bouys and keep an eye out in front of you. They do a really good job marking the rocks but you still got be careful. Average depth of the lake is not much more than 12-16ft with the river about 20-40ft deep. Trolling walleye cranks in the trench at Lonesome Bay will probably produce some "eyes". Frankly Walt, your better off working deep weed lines for NP, LMB and Crappie. I can't say for sure but I don't think you'll get a boat into the bays because the weeds will be topped out and really thick. Scumb Frogs work pretty good in the muck bit I still prefere black buzzers and chartruse #5 Mepps in-lines. North of the bridge around .05 mile on the right is a good bay for LMB and NP and probably won't be totally topped out with weeds. Like I said in my last post the river that will take you to the old armory is good for LMB and NP in some of the small bays off the river. The falls is good also. Two years ago I caught a Gar (by accident) that went 40" and I got it under the falls. The Log Cabins has a bait shop and tackle store and small grocery store along with live bait shop along with a gift shop if you need anything. Oh, by the way, the falls are in Edwardsville if that helps any. It should be about a 6 mile run from where you are staying.
Well enough for now. We leave for Canada this saturday and will be gone till the following week. If I don't talk too ya again, goodluck at BL.
