Opuntia Lake Migratory Bird Sanctuary

The Opuntia Lake Migratory Bird Sanctuary (MBS) is located near Kindersley, in Saskatchewan. It protects quality habitat for thousands of geese, ducks, swans and crane.

Importance of the sanctuary: migratory birds and other wildlife

When the Quill Lakes Migratory Bird Sanctuary was delisted on January 23, 1952, two new sanctuaries were created in the same year to replace it. One of these new protected areas was the Opuntia Lake Migratory Bird Sanctuary. Located 60 kilometres southwest of Biggar, Saskatchewan, this sanctuary is strategically positioned along a major flyway for geese and other waterfowl in an area that is highly susceptible to drought. This makes Opuntia Lake very important and it is highly used in the fall as a resting and feeding area for many species of birds.

It has been estimated that each fall the migratory birds seen in this sanctuary include:

  • 15 000 to 20 000 geese – comprised of Canada geese, white-fronted geese, snow geese and Ross’s geese
  • 30 000 ducks – mostly mallard, northern pintail, and various diving ducks
  • 500 tundra swans
  • 2000 sandhill cranes

Did you know?

During mating season, sandhill cranes perform a dance that involves bowing, jumping, wing flapping and sometimes even playfully tossing sticks and plants into the air.

The lake also supports small numbers of breeding and moulting ducks, shorebirds and other waterbirds.

Landscape

Opuntia Lake itself, situated in the Moist Mixed Grass ecoregion of Saskatchewan, is shallow, saline and located in a deep and broad glacial meltwater channel. Eagle Creek both feeds the lake and acts as its water outlet. Even though a berm and check dam was installed downstream as a water control measure, the water levels of the lake still fluctuate considerably due to the fact that they depend largely on seasonal rains and spring runoff.

During the summer, as water levels progressively decline, mudflats form near the lake, and blue-green algae blooms are known to occur occasionally in the turbid water. The shoreline, particularly near the lake’s inlet and outlet, are vegetated with scatterings of bulrushes and sedges. The aquatic vegetation found in the lake is mostly pondweeds in the deep water and water milfoil in the shallow areas. The higher land around the lake is vegetated with native grasslands along the meltwater channel slopes. These grassy slopes are all used as grazing land for livestock.

Access to the sanctuary

Migratory Bird Sanctuaries, such as Opuntia Lake, are established across the country to protect migratory birds during critical periods of their life cycle. Whether these areas are used for feeding, resting or nesting, they play an important role in the survival of many species.
