Site description Redberry Lake, named for the profusion of buffalo berries (Shepherdia canadensis) that grow in the region, is located in north-central Saskatchewan near the village of Hafford. It is a large, internally drained, saline lake typical of Saskatchewan?s Parkland Region. Water levels on the lake have dropped continuously since it was first surveyed in 1906-09. At that time, the levels stood at about 515 m; today?s level is about 507 m. As a result, the shoreline has been reduced by 36 km, the area of its islands by 250 ha, and its overall area by 2,430 ha. At present the area of the lake is 5,610 ha, including four islands with a combined area of 85 ha. These islands (?Pelican?, ?Gull?, ?Old Tern? and ?New Tern?) are (or were) used by nesting colonial birds. The names, however, do not now reflect the species nesting there. American White Pelicans used Pelican and Gull Islands in 1972; by 1996 they had switched to New Tern, an island that has been exposed only since 1957.
