My son and I just got back from a couple of excellent days in SD. We fished Lake Thompson slough ,Whitewood and oakwood seen lots of fishermen at all those lakes but no fish got back to the motel and the lady at the desk said should have been on ponsett so the next day we went to ponsett caught butloads of perch and several 15" walleye. Lots and lots of fishermen The lake was amazing fished 12 ft of water could see every pebble and stick on the bottom at times we would have 10 or 12 perch looking at our bait was tremendous fun
