- Waterfowl Production Areas of the Northwest Montana Wetland Management District are in Lake and Flathead counties in northwestern Montana. The WPA's are small tracts of wetlands and uplands aquired for waterfowl production, but habitat is provided for a variety of other wildlife. They are open to public hunting and provide many hours of outdoor recreation for sportspersons. Management includes preservation and enhancement of wetlands, while nesting cover or food plots are provided on the uplands.
The Lake County WPA's are located in glacial and lake bed soil deposits and are part of numerous glacial kettles which were formed during the 100,000 year Wisconsin glaciation. Flathead County WPA's consists of seven miles of lake shore and upland areas along the north end of Flathead Lake, including remnants of "delta" islands at the mouth of the Flathead River. Several other Flathead County WPA's are scattered throughout the valley.
