The Gardiner Dam on the South Saskatchewan River in Saskatchewan is the third largest embankment dam in Canada and one of the largest embankment dams in the world. Construction on Gardiner Dam and the smaller Qu'Appelle River Dam was started in 1959 and completed in 1967, creating Lake Diefenbaker upstream and diverting a considerable portion of the South Saskatchewan's flow into the Qu'Appelle River. The dam rises 64 metres (209 feet) in height, is almost 5 km (3.1 mi) long and has a width of 1.5 km (0.93 mi) at its base with a volume of 65,000,000 cubic meters. The dam is owned and operated by the Saskatchewan Water Security Agency.
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.
The Fishing Lakes, also called the Calling Lakes or the Qu'Appelle Lakes, are a chain of four lakes in the Qu'Appelle Valley cottage country about 40 miles (64 km) to the north-east of Regina in the Canadian province of Saskatchewan. The lakes are 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. The Fishing Lakes all follow the course of the Qu'Appelle River, which flows from the west to the east and is part of the Hudson Bay drainage basin. The lakes sit in the deep-cut Qu'Appelle Valley that was formed about 14,000 years ago during the last ice age. Meltwater from the glaciers carved out the valley and as water levels rose and fell, alluvium was left in the wake. These piles of alluvium are what created the separations between the lakes.
Last Mountain Lake, also known as Long Lake, is a prairie lake formed from glaciation 11,000 years ago. It is located in south central Saskatchewan, Canada, about 40 kilometres (25 mi) north-west of the city of Regina. It flows into the Qu'Appelle River via Last Mountain Creek, which flows past Craven. It is approximately 93 km (58 mi) long, and 3 km (1.9 mi) wide at its widest point. It is the largest naturally occurring body of water in southern Saskatchewan. Only Lake Diefenbaker, which is man-made, is larger. The lake is a popular resort area for residents of south-eastern Saskatchewan.
