The river was named for Joseph Brazeau, a linguist associated with the Palliser Expedition.[2]
Course
The river originates in the heights of the Canadian Rockies from Brazeau Lake (which is fed by creeks that flow from Coronet Glacier and the Queen Elizabeth Ranges) and flows east through the Rocky Mountains foothills until it merges into the North Saskatchewan River between Drayton Valley and Rocky Mountain House at Brazeau Forks.
The upper course runs eastwards from Jasper National Park into Brazeau Canyon Wildland Provincial Park. The O'Chiese First Nation is established at the confluence with Nordegg River.
The total length of the river is 210 kilometres (130 mi). The river, and various other local geographic features, were named after Joseph Brazeau, a Missouri-born fur trader working for the Hudson's Bay Company in the area between 1852 and 1864.[3]
Hydroelectric development
The Brazeau Dam Power Plant
The Brazeau River has long been seen as a potential site for hydroelectric power generation. The earliest scheme to harness the power of the river was hatched in 1913 and involved a dam and storage on Brazeau Lake. The potential power generation was estimated at 5,000 to 10,000 kilovolt-amperes, and power would have been transmitted to Edmonton and Calgary, both roughly 400 kilometres (250 mi) from the generator (this was a relatively ambitious plan: long-distance transmission was not common at the time). The plan was scuttled after the discovery of a large underflow at Brazeau Lake, precluding its use as a storage facility.[4]
The 99-square-kilometre (38 sq mi) Brazeau Reservoir was created on the lower course through the construction of the Brazeau Dam. Its hydroelectric power plant is Alberta's largest, with a capacity of 355 megawatts and an annual production of about 394,000 megawatt hours of electrical energy.[2]
An unusual feature of this hydroelectric development, commissioned in 1965, is a pump system capable of lifting water from the reservoir into the 20-kilometre (12 mi) long canal leading to the power plant so that it can operate at low reservoir water levels.
