Well I should let you know the aroma park campground itself is not a very good area for smallmouth. It is where the Kankakee and Iroquois convulge. It's very wide and at about 9 or 10 feet deep in summer pool.Also tends to be muddy. It fishes more like a small reservoir than a river. It's still a good spot for numerous species,but the good news is your only 10 minutes away from your proto typical Kankakee smallmouth water. Just head upstream from aroma park and you'll find more of your water willow pools and shallow rock riffle habitat.
I'd rather be fishing!
