Can you duck hunt Lake Knickerbocker in Gainesville, while complying to all state and federal hunting regulations? Pat Robbins, spokesman for the Army Corps of Engineers, which owns the 45-acre lake on the Chattahoochee Golf Course in Gainesville, said duck hunting is allowed but there are a number of restrictions. Hunting is not permitted within 1,000 feet of a dock, house, bridge, road, boat ramp, marina, open recreational area or any structure, according to the Department of Natural Resources.
