The South Saskatchewan
Saskatchewan
River is a major river in Canada
Canada
that flows through the provinces of Alberta
Alberta
and Saskatchewan. For the first half of the 20th century, the South Saskatchewan
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
Saskatoon
was destroyed by ice carried by the river. The construction of the Gardiner Dam
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
Saskatchewan
flows for 1,392 kilometres (865 mi). At its mouth at Saskatchewan
Saskatchewan
River Forks, it has an average discharge of 280 cubic metres per second (9,900 cu ft/s) and has a watershed of 146,100 square kilometres (56,400 sq mi), 1,800 of which are in Montana
Montana
in the United States and 144,300 square kilometres (55,700 sq mi) in Alberta
Alberta
and Saskatchewan.[1]

Course[edit] The river originates at the confluence of the Bow and Oldman Rivers near Grassy Lake, Alberta. The waters of these two rivers, in turn, originate from glaciers in the Rocky Mountains
Rocky Mountains
near the British Columbia and Montana
Montana
border.[2] The Red Deer River
Red Deer River
is a major tributary of the South Saskatchewan
Saskatchewan
merging 16 kilometres (10 mi) east of the Alberta- Saskatchewan
Saskatchewan
border. The Lake Diefenbaker reservoir was created with the construction of the Gardiner and Qu'Appelle River
Qu'Appelle River
dams in Saskatchewan. Water from the South Saskatchewan
Saskatchewan
flowing through the dams provides approximately 19 percent of the hydro-electricity generated by SaskPower.[3] Downstream from the dam the river flows north through Saskatoon
Saskatoon
and joins the North Saskatchewan
Saskatchewan
River east of Prince Albert at the Saskatchewan
Saskatchewan
River Forks — thus forming the Saskatchewan
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
Saskatoon
area were formed by oxbows of the South Saskatchewan
Saskatchewan
River, most notably Moon Lake and Pike Lake.[2] A 2009 report,[4] produced by WWF- Canada
Canada
which analysed the river flow on 10 major Canadian rivers reported that the South Saskatchewan
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
Saskatchewan
River by 70 percent. Developers and governments have been cautioned to protect and restore the river with sustainable projects and limit water diversion.[5] Dickson Dam
Dam
regulates water supply downstream on the Red Deer River; the Bassano Dam
Dam
and 11 other dams divert water on the Bow River
Bow River
and in the Bow River
Bow River
basin; and the Oldman River
Oldman River
Dam
Dam
and Waterton-St. Mary Headworks System manage water flow downstream of the Oldman River.[6] 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 the irrigation benefits.[7][8] Tributaries[edit]

Geology[edit] Sections of the riverbank along the South Saskatchewan
Saskatchewan
River are prone to slumping.[9] Since its founding, the city of Saskatoon
Saskatoon
has dealt with a number of slope failures. Controlling riverbank development was a factor in establishing the Meewasin Valley Authority
Meewasin Valley Authority
in 1979.[10] Fish
