- The District was first staffed in 1962, and combined with Des Lacs NWR Complex in 1975. The District contains portions of three physiographic areas; Drift Plain, Missouri Coteau, and Missouri Slope.
Over 50% of the waterfowl production areas lie in the Missouri Coteau, a terminal moraine that crosses the District diagonally from northwest to southeast, and contains some of the highest densities of wetlands (potholes) in the prairie pothole region. The Coteau also contains some of the largest blocks of native prairie in North Dakota, with much of the Coteau being used for grazing and not tilled.
Northwestern North Dakota remains one of the best duck producing areas in the Prairie Pothole region because of the remaining grasslands and low predation rates.
