Upper Rousay Lake Migratory Bird Sanctuary

The Upper Rousay Lake Migratory Bird Sanctuary (MBS) is located near Yorkton, in Saskatchewan. It offers a quality habitat where many birds can feed, rest and nest.

Importance of the sanctuary: migratory birds and other wildlife

The Upper Rousay Lake Migratory Bird Sanctuary is known to be a wonderful breeding and moulting habitat for waterfowl in Saskatchewan’s Aspen Parkland ecoregion. Located 6 kilometers southwest of Yorkton, this sanctuary is one of five migratory bird sanctuaries that were established on November 3, 1948, to replace five others that were no longer deemed to be suitable migratory bird habitat due to drought conditions.

Landscape

Upper Rousay Lake is part of a larger wetland complex of shallow, interconnected bodies of water including Lower Rousay, York, Leech and Crescent lakes. Water levels in the complex fluctuate substantially, and are largely dependent on local runoff and some intermittent streams. Upper Rousay Lake itself is shallow, with an average depth of 0.5 meters. The sanctuary includes numerous bays, peninsulas and temporary islands, as well as several artificial islands constructed by Ducks Unlimited Canada.  

The lake shoreline is vegetated by sedges and associated wet meadow grasses and scattered clumps of aspen and willow occur on its periphery. The lands surrounding the lake were cultivated and are now used for tame pasture, hay and cereal crops.

It is estimated that 23 to 28 percent of the world’s wetlands are in Canada. The Canadian Wetland Inventory is a tool created in partnership with Ducks Unlimited Canada that is mapping, classifying and looking at the potential threats to all wetlands across the country. This information is very beneficial for making informed conservation decisions.
