I say out of a gravel or quarry pit in southern Ohio. I have fished the pits in West Carrolton/Miamisburg/Moraine for 30 plus years and have caught a 7 pound smallie/two 8 pound LM/a truck load of LM over 5 pounds and numerous bass estimated over 10 pounds have been seen on the bed in spring there. I say pits and quarries.
