23-744: 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,

46-704: A watershed of 146,100 square kilometres (56,400 sq mi), 1,800 of which are in Montana in the United States and 144,300 square kilometres (55,700 sq mi) in Alberta and Saskatchewan. The river originates at the confluence of the Bow and Oldman Rivers , north of Grassy Lake, Alberta at the incorporated community of Bow Island, not to be confused with the town of Bow Island, Alberta . The waters of these two rivers, in turn, originate from winter snowpack and rainfall in

69-701: Is a provincial recreation site in the Canadian province of Saskatchewan at the confluence of the North Saskatchewan and South Saskatchewan Rivers . The rivers, which have their headwaters in the Rocky Mountains , come together to form the Saskatchewan River . A major intersection when waterways were important to transportation on the Canadian Prairies , first with the fur trade and then during

92-634: 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 . Two main gravity fed aqueducts (canals) from the lake were built in 1967 as part of the South Saskatchewan River Project to supply water to downstream reservoirs for irrigation, drinking water, and industrial uses. The Westside Irrigation Project supplies water to

115-679: Is heavily wooded with steep banks. There is a tourist picnic site, hiking trails, and historic markers. In 1692, Englishman Henry Kelsey — while working for the Hudson's Bay Company — was the first European to reach the Saskatchewan River Forks. While he didn't set up a trading fort at the Forks, his journey helped open up the prairies for the North American fur trade . Trading posts along rivers were important to European fur traders. In 1751,

138-782: Is in Alberta on the Canadian Forces Base Suffield . Covering an area of 460.71 km (177.88 sq mi), the IBA consists of two sections on the base along the north-western shore of the South Saskatchewan River. The landscape consists of mixed grasslands with intermittent salt lakes and natural springs. Birds found at the site include the burrowing owl , loggerhead shrike , long-billed curlew , ferruginous hawk , McCown's longspur , Brewer's sparrow , upland sandpiper , Baird's sparrow , Sprague's pipit , grasshopper sparrow , western meadowlark , golden eagle , and

161-613: Is in Saskatchewan and follows the course of the South Saskatchewan River from the Alberta / Saskatchewan border east to the Lancer Ferry crossing and includes the river's valley and the fork with the Red Deer River . The site covers an area of 208.6 km (129.6 mi). The valley floor is heavily wooded and includes trees such as the eastern cottonwood , Manitoba maple , peach-leaved willow , and the green ash . Birds found at

184-505: Is named for a former Premier of Saskatchewan and longtime federal cabinet minister, James G. Gardiner . South Saskatchewan River 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

207-572: Is the confluence of the South and North Saskatchewan Rivers and is the beginning of the Saskatchewan River . For the first half of the 20th century, the South Saskatchewan would completely freeze over during winter, creating spectacular ice breaks and dangerous conditions in Saskatoon , Medicine Hat , and elsewhere. At least one bridge in Saskatoon was destroyed by ice carried by the river. The construction of

230-623: The Gardiner Dam in the 1960s, however, lessened the power of the river by diverting a substantial portion of the South Saskatchewan's natural flow into the Qu'Appelle River . By the 1980s many permanent sandbars had formed due to the lowering of the level of the river. From the headwaters of the Bow River, the South Saskatchewan flows for 1,392 kilometres (865 mi). At its mouth at Saskatchewan River Forks , it has an average discharge of 280 cubic metres per second (9,900 cu ft/s) and has

253-592: The Rocky Mountains near the British Columbia and Montana border. Glacier and snowmelt from the Rocky Mountains and foothills contributes nearly 90% of the annual flow, with most of that contribution during July and August. The Red Deer River is a major tributary of the South Saskatchewan merging 16 kilometres (10 mi) east of the Alberta-Saskatchewan border. The Lake Diefenbaker reservoir

276-462: The prairie falcon . Besides the aforementioned birds, the habitat is also important for several animals,  including the  mule deer , pronghone antelope , Ord's kangaroo rat , pygmy short-horned lizard , western hognosed snake , and the prairie rattlesnake .

299-409: The riverboat era, today the Saskatchewan River Forks attract tourists, canoeists, and recreational fishermen. The recreation site, which is maintained by the province of Saskatchewan, is about 50 kilometres (31 mi) east of Prince Albert and 33 kilometres (21 mi) north of Weldon . Access is 13 kilometres (8.1 mi) off Highway 302 . The park is on the west side of the river fork and

322-629: The Red Deer River; the Bassano Dam and 11 other dams divert water on the Bow River and in the Bow River basin; and the Oldman River Dam and Waterton-St. Mary Headworks System manage water flow downstream of the Oldman River. The proposed Meridian dam 30 kilometres (19 mi) west of Leader and 95 kilometres (59 mi) north east of Medicine Hat was cancelled due to project costs outweighing

345-553: The Saskatchewan River. For approximately 60 kilometres (37 mi) near Saskatoon, the Meewasin Valley Authority is responsible for conservation of the river environment. Numerous lakes in the Saskatoon area were formed by oxbows of the South Saskatchewan River, most notably Moon Lake and Pike Lake . A 2009 report, produced by WWF-Canada which analysed the river flow on ten major Canadian rivers reported that

368-430: The South Saskatchewan River was the most at risk. Climate change , agricultural and urban infrastructure water use, and dams producing hydroelectricity , have all combined to reduce the flow of the South Saskatchewan River by 70 percent. Developers and governments have been cautioned to protect and restore the river with sustainable projects and limit water diversion. Dickson Dam regulates water supply downstream on

506-472: Was a factor in establishing the Meewasin Valley Authority in 1979. There are four Important Bird Areas (IBA) of Canada along the South Saskatchewan River. Two – Galloway and Miry Bay (SK006) and East Lake Diefenbaker (SK055) – are located at Lake Diefenbaker and the other two are farther upstream along the river's course.

Water from the South Saskatchewan flowing through the dams provides approximately 19 percent of the hydro-electricity generated by SaskPower. Downstream from the dam the river flows north through Saskatoon and joins the North Saskatchewan River east of Prince Albert at the Saskatchewan River Forks — thus forming
