The Nettle Lake Sewage Ponds often feature migrating ducks and are an excellent place to check when duck hunters are at Lake La Su An. The ponds are on Williams County Road 5-75 just west of Lake La Su An. From Lake La Su An Wildlife Area, take County Road R west about a mile. At this point you have to turn left to stay on County Road R. The ponds will be on your left within a half-mile.
