Ponass Lakes

Ponass Lakes are made up of six shallow, marshy lake basins ranging in size from 98 ha to 1631 ha in the central part of the Canadian province of Saskatchewan. The lakes and marsh are in the aspen parkland ecoregion and are surrounded by groves of trembling aspen and farmland. Water levels are controlled by a series of dams operated by Ducks Unlimited Canada. The outflow for the lakes and marsh is from a short creek at the north end. The creek flows into George Williams Lake, which is within the Red Deer River drainage basin. The lakes and marsh are in the RM of Ponass Lake No. 367 and access is from Highway 35.

Ponass Lakes and surrounding marsh are nationally important for migratory birds and are within an Important Bird Area (IBA) of Canada. The Ponass Marsh was the first designated Heritage Marsh in Saskatchewan.
