Welcome to Black L.
I fish BL Summers and in Sept. whenever I can.
Most often for bass and pike.
Both of these fish will take surface lures in the early morn and evenings. During the day, the bass may be caught on the surface in the weeds.
Almost all of my fishing is in the weeds, over the weeds or in deeper water next to the weeds. Therefore I think weed less or nearly weed less when selecting lures.
My "go to" lures are spinner baits, buzz bates, 5 in. Sinkos, large Johnson silver minnow, large silver rattle trap, and last Summer I did very good with the pike on a 6 in. paddle tail soft bait that looked like a perch, fished with a large weedless jig head to get it down and through the weeds. A steel leader is a must.
We do most of our fishing South of the bridge at Edwardsvill.
There are some pics. at the bottom of this page:http://www.reelfishingdeals.com/pictures5.html
The cat was caught on the rattle trap, you can just see it in the net and the wally was caught on the silver minnow.
Black L is a great fishery, especially considering all the pressure it gets, and you never know what you might see or catch.
For simplicity, my wife fishes with the Sinko Texas rig with a bullet sinker to get it down and through the weeds. She throws it out , doesn't pay any attention to it, drags it along, moves it know and then, watches the wild life and other boaters and catches all the fish.
Hope this helps & Have a nice Christmas,
