The Qu'Appelle River is a river in the Canadian provinces of Saskatchewan and Manitoba that flows 430 kilometres (270 mi) east from Lake Diefenbaker in south-western Saskatchewan to join the Assiniboine River in Manitoba, just south of Lake of the Prairies, near the village of St. Lazare. It is in a region called the Prairie Pothole Region of North America, which extends throughout three Canadian provinces and five U.S. states. It is also within Palliser's Triangle and the Great Plains ecoregion.

Mission Lake, also known as Lebret Lake, is a lake in the Canadian province of Saskatchewan. It is one of four lakes in the Qu'Appelle Valley known as the Fishing Lakes. Echo Lake is upstream and Katepwa Lake is downstream. The lake was named Mission after the Catholic mission at Lebret. Highways 22 35, and 56 provide access to the lake.
