About the Refuge

grebes_512

Lake Andes National Wildlife Refuge is a place of wetlands, grasslands, and riverside forests. During spring and fall migrations, clouds of waterfowl and shorebirds darken the sky.

  • History

    history_fish150

    This was a lake the Sioux Indians knew well, for they frequently made camp here during their pursuit of migrating herds of buffalo and flocks of waterfowl. Around the turn of the century, as settlements were becoming firmly established, the lake became well-known as a fine place to fish. Several resorts were built near the lake to accommodate visitors who arrived by train. 

     
    The Refuge was established in 1936 with the purchase of 365 acres of land in the Owen's Bay area. Subsequent purchases of land have been made on a continuing basis.

     

    The meandered lake bed is protected by a 1939 easement from the State of South Dakota. The easement authorizes the U.S. Fish and Wildlife Service to flood the lake bed and maintain a closed refuge for migratory birds and other wildlife. However, the center portion of the lake bed is open to hunting.
     

  • Geography

    dike150

    Located in South Dakota, these lands and waters are vitally important to the nation’s migratory bird populations – waterbirds and songbirds nest here in great numbers. Lake Andes is a natural, shallow prairie lake whose water supply depends entirely on natural runoff. Lake levels periodically rise and fall, with the entire lake going dry about once every twenty years.

     

    Two dikes separate Lake Andes into three separate units, but the lack of a permanent water supply allows very little manipulation of water levels to encourage growth of aquatic foods or assure duck broods of adequate water in drier years. Only the Owen's Bay marsh, fed primarily by the waters from a free-flowing well, permits effective manipulation of water levels to maximize the bay's benefit to wildlife.

     

  • Habitat

    A diversity of habitat types exists on Lake Andes NWR. As a result of the habitat diversity, a variety of wildlife can be seen throughout the Refuge. The tall vegetation of the uplands provide opportunities to see grassland bird species such as meadowlarks, eastern kingbirds, bobolinks, red-winged blackbirds, and yellow-headed blackbirds. The rich food resources supplied by Lake Andes, Owens Bay, and the prairie ponds support large numbers of waterfowl, especially during migration. Ring-necked pheasants and white-tailed deer are often seen scurrying through the cottonwoods and other tall vegetation of Lake Andes NWR.
