The Northwest Montana Wetland Management District is located in the U.S. state of Montana and is an integral part of the National Bison Range Complex along with four other wildlife refuges and the National Bison Range. The district comprises numerous small wetland environments set aside primarily to protect areas for waterfowl. The district comprises 14 separate Waterfowl Production Areas (WPA)'s totalling 8,452 acres (34 kmē) and one 6,300 acre (25.5 kmē) Conservation easement along the north shores of Flathead Lake. Some of the land is located on the Flathead Indian Reservation (known as the Tribal Trust Lands of the Confederated Salish and Kootenai Tribes) and they continue to have claim over the land provided they assist in maintaining the resource. The Northwest Montana Wetland Management District is administered by the U.S. Fish and Wildlife Service, an agency within the U.S. Department of the Interior.

Of the 200 species of birds reportedly observed on district lands, Canada Geese, Peregrine Falcon, Green-winged teal, Meadowlark, Owls, Ring-necked Pheasant, Great Blue Heron and numerous species of Ducks can be found here. Small Mammals such as the Porcupine, Muskrat, Mink, Beaver and Skunk are also common.
