Moose Lake is a lake located near the Saskatchewan River Delta in Manitoba, Canada. It is separated into two irregularly shaped lobes, North Moose Lake and South Moose Lake, by the Moose Lake Narrows Control Structure, which was built in 1964. South Moose Lake drains south into Cedar Lake via Moose Creek; these two lakes form the reservoir of the Grand Rapids Generating Station, and the sluice gates at Moose Lake Narrows helps regulate their water levels. The lake as a whole lies at an elevation of 255 metres (837 ft) and covers 1,367 square kilometres (528 sq mi). The community of Moose Lake is on the south shore of the lake.
