I've been looking for a pond to fish channel cats around my house. I have found several, and I have questions about 2 of them. First is about 4 acres, and is(at least where I have seen) between "6 and '3 feet deep, and there are card everywhere, you can't throw a rock in the water without spooking 20 of them. Could it hold cats? Or is it to shallow and packed with carp? And secondly, I found a pond, where there is an earthen dam, but the water flows in to a massive culvert and under the dam, where would the deep hole be here? It is maybe a half an acre.
