Culdesac Lake

Culdesac Lake is a lake in the Canadian provinces of Saskatchewan and Manitoba. It is situated in the Saskatchewan River Delta and is in the Mid-Boreal Lowland ecoregion. It is surrounded by muskeg and boreal forest. Its primary inflow is from a channel connected to Culdesac River, which is a tributary of Carrot River. An outlet from the eastern end of Culdesac Lake connects it to the Pasquia River — a tributary of the Saskatchewan River. The lake falls within the Cumberland Marshes (SK 102) Important Bird Area of Canada.

Most of Culdesac Lake is in the RM of Hudson Bay No. 394 in Saskatchewan while only the eastern most end is in Northern Manitoba. There are no communities along the lake's shore and Highway 9 is the closest highway. On the northern shore is a Saskatchewan provincial recreation site.
