Basin and Middle Lakes Migratory Bird Sanctuary
Basin and Middle Lakes Migratory Bird Sanctuary (MBS) is situated 40 km north of Humboldt, Saskatchewan. It consists of two relatively large saline lakes 1.5 km apart located in the Boreal Transition ecoregion of Saskatchewan. Both lakes are subject to severe water-level fluctuations, as spring runoff and seasonal rains are their major water source. Basin Lake, with an average depth of 9 m, has several islands, the number of which depends upon water conditions. Middle Lake, considerably more shallow with an average depth of 1 m, has one island. Basin Lake has extensive rocky and sandy areas along its shoreline, a dry meadow zone or mud flats, and is surrounded by aspen, willow and some white spruce. The shoreline of Middle Lake is similar, but extensive wet meadow zones occur on the east and south shores. Both lakes are saline and slightly to moderately alkaline. Until the mid-1970s, Basin Lake supported a Whitefish fishery, which no longer exists owing to the salinity of the lake. Basin Lake and its surrounding uplands was a proposed International Biological Program site. In 2001, Basin and Middle Lakes were designated an International Bird Area for their global significance for shorebirds and waterfowl.
Importance of the Migratory Bird Sanctuary
Basin and Middle Lakes MBS was established on March 9, 1925. This sanctuary is a major migratory staging area for waterfowl and swans. In the fall, Basin Lake attracts up to
20 000 ducks, 400 Canada Geese and 600 Tundra Swans, while Middle Lake supports half these numbers. Breeding populations of diving and dabbling ducks and Canada Geese on both lakes are restricted by the lack of suitable nesting habitat. Several hundred ducks, primarily divers, and geese also use the lakes during their moulting period in summer.
The MBS is also important for shorebirds during spring migration. The endangered Piping Plover has been recorded here.
Access and Activities
MBSs are established for the protection and conservation of migratory birds. Activities that could harm migratory birds, their nests or their eggs are prohibited.
MBSs can be and have been established on private, provincial, territorial and federally owned lands. Access to each MBS varies by site and is at the discretion of the landowner and land manager.
Where MBSs are located on federal land, Environment and Climate Change Canada is responsible for the management and protection of migratory birds, nests, eggs and habitat. Where MBSs are located on provincial land, Environment and Climate Change Canada is responsible for the protection of migratory birds and their nests, while the chief game officer of the province is responsible for the management of habitat. Where MBSs are located on private or municipal land, Environment and Climate Change Canada is responsible for the protection of migratory birds and their nests. Habitat management is the responsibility of the landowner.
Public access to the MBS is at the discretion of the many private landowners adjacent to these lakes. There are limited municipal road access points. The standard prohibitions under the Migratory Bird Sanctuary Regulations apply to this site: hunting migratory birds is prohibited, and no person shall disturb, destroy or take the nest of a migratory bird or have in his or her possession a live migratory bird, or a carcass, skin, nest or egg of a migratory bird, except under the authority of a permit issued by Environment and Climate Change Canada or unless authorized by the Regulations. Possession of firearms or other hunting appliances is prohibited. Dogs and cats must not be allowed to run at large.
For more information on entry, activities and permits in MBSs, please visit the Management and Activities section of the Migratory Bird Sanctuaries website. For more information on protected areas managed by Environment and Climate Change Canada in Quebec, please contact the regional office.
For greater certainty, nothing in this document shall be construed so as to abrogate or derogate from the protection provided for existing Aboriginal or treaty rights of the Aboriginal peoples of Canada by the recognition and affirmation of those rights in section 35 of the Constitution Act, 1982.
