Fishing should be very good on that stretch. Jig and minnow on any current seams between the dam and the confluence should have a mixed bag of fish. Crappie, walleye, sauger, smallies, sheepies, catfish, etc. Jig and half a crawler will probably also work.
The other best bet is to troll the shorelines on that stretch. If you pickup a couple of fish spot lock or anchor and throw cranks or live bait.
Water temp was still close to 60 last weekend so it’s not the plastics bite yet for me. Not sure the age of your kids but live bait and trolling cranks is a good bet right now and easy to do.
