Lake of the Rivers^[1] is a salt lake in the Canadian province of Saskatchewan. It is in the Prairie Pothole Region of North America, which extends throughout three Canadian provinces and five U.S. states, and within Palliser's Triangle and the Great Plains ecoregion of Canada.^[2] The lake is long, narrow, shallow, and located in a valley that was formed by glacial meltwaters at the end of the ice age. The north end of the valley opens up to Old Wives Lake and south-east along the valley is Willow Bunch Lake. Beyond Willow Bunch Lake, the valley opens up into the Big Muddy Badlands.^[3]

The closest town to Lake of the Rivers, Assiniboia, is about 13 km (8.1 mi) west of the southern end of the lake. The lake spans two rural municipalities, Lake of the Rivers No. 72 and Lake Johnston No. 102, and sits at the northern slope of the Missouri Coteau. The hamlet of Ardill and Highways 715 and 2 are at the northern end of the lake while Highway 717 is at the southern end. Less than 2 km (1.2 mi) from the southern end of the lake is the community of Willows and Willows Reservoir.^[4] A section of Assiniboia Regional Park is at the reservoir and the river leaving the reservoir is a tributary of Lake of the Rivers.
