Fished a couple of sections on the Arkansas side today. Didn't have a ton of action but did catch 2 1-1.5 pound smallmouth, 1 green sunny, and 1 longear sunny on a small, black bead-head woollybugger with an extra #4 splitshot. Also caught a half-pound smally and a greenie on a chartreuse clouser. As I pulled in the smallmouth, a 3-4 pound largemouth chased it out of the depths and nipped it repeatedly. Tried like heck to hook that guy but to no avail.
Water was at a very wadeable level throughout most of the places I fished, but it was pretty dingy in the holes. Early in the morning, I had luck with the woolybugger before the sun broke through the clouds. The chartreuse clouser was more successful in the sunny afternoon. I haven't been on the Illinois in 2 years, and much of the river is completely different from what it was then due to all the flooding. There's a lot of new submerged timber and deep holes that the dingy water hides, so be careful while wading if you haven't been there in a while.
If the rain holds off and the water can drop another 6-inches or foot and clear up, it could be really awesome fishing.
