Craven Dam is at the confluence of the Qu'Appelle River and Last Mountain Creek [1] and immediately east of the village of Craven on the Qu'Appelle River at LSD SW 24-20-21 W2. It is in the Canadian province of Saskatchewan in the RM of Longlaketon No. 219. The dam does not create a reservoir as its purpose is to regulate water flow along the Qu'Appelle River. The dam is operated by the Saskatchewan Water Security Agency [2] and can be accessed on the north side by Highway 99.
Craven Dam is the dividing point between the upper and lower watersheds of the Qu'Appelle River. The total drainage basin of the Qu'Appelle River upstream from the dam is 23,443 km2 (9,051 sq mi) and it is divided into five sub-basins, which include Lanigan-Manitou, Wascana Creek, Last Mountain Lake, Upper Qu'Appelle, and Moose Jaw River. [3]
The original Craven Dam was built in 1943 and did not include a fishway. Starting in August of 2002 and finishing in 2003, Agriculture and Agri-Food Canada rebuilt the dam. The new dam included a 29.5-metre (97 ft) long fishway that runs along the north side. It is 3.6 m (12 ft) wide and includes seven vertical baffles within the structure that are designed to reduce flow velocities to create refuges for migrating fish. At the upstream end of the fishway, there is a 1.5 by 1.5-metre gated bay. The dam itself is 28.4 m (93 ft) long and 4.9 m (16 ft) high. The dam consists of four gates, each 4.5 m (15 ft) wide and 2.15 m (7 ft 1 in) high. [4]
Water flow can be reduced through the dam's gates so that water backfloods up Last Mountain Creek and into Last Mountain Lake. In that case, Last Mountain Lake, which is a natural lake, becomes a reservoir. When the dam's gates are open, water from Last Mountain Lake and the Qu'Appelle River flow east and downstream into Pasqua Lake, which is one of the Fishing Lakes.
The fishway is designed with bays that allow researchers to drop a steel fish trap to capture fish for study. Passive Integrated Transponder (PIT) tags were implemented into the abdominal cavity of fish and used to assess fish movements through the fishway. Some of the fished being monitored include the bigmouth buffalo, common carp, lake whitefish, northern pike, quillback, walleye, white sucker, and yellow perch. [5]
The South Saskatchewan River is a major river in the Canadian provinces of Alberta and Saskatchewan. The river begins at the confluence of the Bow and Oldman Rivers in southern Alberta and ends at the Saskatchewan River Forks in central Saskatchewan. The Saskatchewan River Forks is the confluence of the South and North Saskatchewan Rivers and is the beginning of the Saskatchewan River.
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 Dam is the smaller of two embankment dams: which created Lake Diefenbaker in Saskatchewan, Canada. The larger dam is Gardiner Dam, the biggest embankment dam in Canada and one of the biggest in the world. Construction of both dams began in the 1959 and was completed in 1967. The dam keeps the flow of water in the Qu'Appelle River relatively constant, as the Qu'Appelle River formerly dried up in many places every summer at the conclusion of the spring freshet from the Rocky Mountains, which feeds the South Saskatchewan River. This along with Buffalo Pound Dam at Buffalo Pound Lake, which supplies water to Regina, Moose Jaw and the Mosaic potash mine at Belle Plaine, keeps the lake from fluctuating excessively. The Canadian Pacific Railway crosses the river via the top of the dam, and the dam was designed with this type of loading in mind. The dam is 3100 metres long and 27 metres high. Douglas Provincial Park extends from the dam to Mistusinne.
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.
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.
Wascana Creek is a river in the Canadian province of Saskatchewan. It is a tributary of the Qu'Appelle River.
Candle Lake is a reservoir in the central part of the Canadian province of Saskatchewan in the boreal forest, approximately 80 kilometres (50 mi) north-east of Prince Albert. A dam completed in 1979 at the southern end of the lake regulates water levels; several small creeks feed into the lake and Torch River flows out of the lake at the dam. Candle Lake Provincial Park surrounds most of the lake and the resort village of Candle Lake is at the southern end.
Buffalo Pound Lake is a eutrophic prairie lake in Saskatchewan, Canada, formed from glaciation about 10,000 years ago, on the Qu'Appelle River approximately 28 kilometres (17 mi) north of Moose Jaw and 11 kilometres (6.8 mi) north-east of Tuxford. The lake gets its name from the method used by First Nations people to capture the bison using the natural topography as corrals or buffalo pounds. Bison, once numbering more than 60 million on the prairies but almost extinct by 1900, were reintroduced into the area in 1972.
Blackstrap Lake is a man-made reservoir in central Saskatchewan, Canada, south of Saskatoon in the Rural Municipality of Dundurn No. 314. The lake was created as a reservoir in 1967, as part of the Saskatoon South East Water Supply System. Blackstrap Lake has an area of 1,200 ha and is generally used to support irrigation, and the industrial and municipal water supply.
Moose Mountain Lake is a reservoir in the Canadian province of Saskatchewan. It is located in the RM of Golden West No. 95 in the Prairies Ecozone of Palliser's Triangle at the western edge of Moose Mountain Upland. Moose Mountain Creek is both the primary inflow and outflow of the lake; it enters at the north end and leaves at the dam in the south end. A secondary inflow that comes from Gooseberry Lake enters on the western side near the south end.
Last Mountain Creek is a river in south-central Saskatchewan. It is a tributary of the Qu'Appelle River 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.

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. Avonlea Creek is a main tributary of the Moose Jaw River, which is part of the Upper Qu'Appelle Watershed and the Hudson Bay drainage basin.
Echo Lake is a lake along the course of the Qu'Appelle River in the Canadian province of Saskatchewan. Echo Lake is so named because of the echo heard by the First Nations while paddling on the lake. It is one of four lakes that make up the Fishing Lakes. Pasqua Lake is upstream and Mission Lake is downstream. The lake can be accessed by Highway 56 and Highway 210. In 1942, a 4-metre (13 ft) high dam was built on the Qu'Appelle River at Echo Lake's outflow to control the lake's water levels.
Spruce River, also called Little Red River, is a river in the north-central region of the Canadian province of Saskatchewan. It begins in the Waskesiu Hills in Prince Albert National Park and flows generally in a southward direction through boreal forests, glacier-carved hills and valleys, muskeg, and prairie en route to the North Saskatchewan River at the east end of the city of Prince Albert.
Makwa River is a river in the Canadian province of Saskatchewan in the transition zone between parkland and boreal forest. Makwa is Cree for Loon. The upper reaches of the Makwa River's watershed reach just across the border into Alberta and includes lakes such as Hewett, Ministikwan, Makwa, and Jumbo.
Reid Lake, also known as Duncairn Reservoir, is a man-made reservoir in the Canadian Province of Saskatchewan. Reid Lake was formed with the construction of the Duncairn Dam in a glacial meltwater channel along the course of Swift Current Creek in 1942. The reservoir was originally built to supply water for the city of Swift Current, for irrigation projects, and to regulate Swift Current Creek levels downstream. The entire lake is part of the Duncairn Reservoir Migratory Bird Sanctuary.
Dellwood Reservoir is a reservoir in the Canadian province of Saskatchewan in the Rural Municipality of Usborne No. 310. The reservoir was built along the course of Dellwood Brook as part of South Saskatchewan River Project. That project, originating at Gardiner Dam of Lake Diefenbaker, involved the building of aqueducts and a series of reservoirs to supply water for irrigation, consumption, and industry. The reservoir is about 22 kilometres (14 mi) north-east of the town of Watrous and access is from Highway 668.
