The lake is part of the Yorkton wetland complex located on the level to gently rolling terrain in the boreal parkland ecoregion of Saskatchewan. The lake has an average depth of 0.5m, and contains a number of bays, peninsulas and temporary islands, as well as several man-made islands. The entire shoreline of the lake consists of sedge and associated wet meadow grasses. Other vegetation includes scattered clumps of aspen, willow, and maple. Some emergent vegetation includes bulrush, associated marshes, cattail, spangletop, and phragmiles.
Sedges occur in many areas.
Submergent aquatics include pondweeds, water milfoil, mare's tail, bladderwort, wigeon grass, and associated species. This sanctuary provides excellent breeding and moulting habitat for waterfowl. The sanctuary is protected by Migratory Bird Sanctuary Regulations under the Migratory Birds Convention Act. Part of it is protected by Provincial Game Preserve regulations under the Provincial Wildlife Act. There are regular patrols of the area by the Yorkton, Saskatchewan detachment of the R.C.M.P. and conservation officers of the Saskatchewan Department of Parks and Renewable Resources.
