- It includes the western-most extension of the glaciated prairie pothole habitat of the Northern Great Plains and the Blackfoot River valley, a glaciated inter-mountain valley west of the continental divide. The 21 waterfowl production areas (WPAs) in the district are extremely varied in habitat types and include prairie grasslands, fresh and saline wetlands, riparian and montane forests, and rivers. Habitat conservation easements protect both wetlands and upland habitat in the WMD from conversion to uses incompatible with wildlife. The primary role of the WMD is conservation of habitat for waterfowl but a wide variety of other species are also benefitted including sandhill cranes, bald eagles, grizzly bears, deer and elk. Management practices include reseeding grasses and forbs on former cropland and restoring drained wetlands. Occasionally burning, haying or grazing are used as tools to stimulate growth of vegetation or to manage weeds. All WPAs except one are open to public hunting in accordance with State of Montana regulations.
Benton Lake Wetland Management District (WMD) covers 13 square miles in north-central Montana.
