Last Mountain Lake. 24/05/82; Saskatchewan; 15,602 ha; 51°20'N 105°15'W. International Biological Programme Site; National Wildlife Area, Migratory Bird Sanctuary; National Historic Site. A network of shallow, marshy bays and inlets, separated by points and islands, including potholes and saline wetlands supporting fringing reedbeds. During the fall migration, up to 75,000 Grus canadensis cranes and 400,000 Anatidae (ducks, geese, swans, etc.) rest and feed here. The islands support nesting colonies of numerous species of water and prairie birds. The site serves as a drought refuge for birds and as wintering habitat for deer, supports various prairie mammals, and provides some of the richest spawning and nursery grounds in Saskatchewan for numerous fish species, including the vulnerable fish Ictiobus cyprinellus, rare over most of its range. A self-guided information programme is available for visitors, and recreational use is increasing. Ramsar site no. 239. Most recent RIS information: 2001.
