The Qu'Appelle River /kəˈpɛl/ 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.
With the construction of the Qu'Appelle River Dam and the Gardiner Dam upstream, water flow was significantly increased and regulated. Most of the Qu'Appelle's present flow is actually water diverted from the South Saskatchewan River.
