Map of the Peace River watershed in western Canada

The Peace River (French: rivière de la Paix) is a river in Canada that originates in the Rocky Mountains of northern British Columbia and flows to the northeast through northern Alberta. The Peace River flows into the Slave River, a tributary of the Mackenzie River. The Mackenzie is the 12th longest river in the world, preceded by the Mekong and followed by the Niger River. The Finlay River, the main headwater of the Peace River, is regarded as the ultimate source of the Mackenzie River.

History

Peace River in Fort Vermilion, Alberta.

The regions along the river are the traditional home of the Dane-zaa people, called the Beaver by the Europeans. The fur trader Peter Pond is believed to have visited the river in 1785. In 1788 Charles Boyer of the North West Company established a fur trading post at the river's junction with the Boyer River.

In 1792 and 1793, the explorer Alexander Mackenzie travelled up the river to the Continental Divide.^[3] Mackenzie referred to the river as Unjegah, from a native word meaning "large river". The Peace River, or Unchaga or Unjaja, was named after Peace Point near Lake Athabasca, where the Treaty of the Peace was celebrated by the smoking of a peace pipe. The treaty ended the decades of hostilities between the Beaver (Athapascan branch) and the Cree, in which the Cree dominated the Dane-zaa until a smallpox epidemic in 1781 decimated the Cree. The treaty made the Peace River a border, with the Dane-zaa to the North and the Cree to the South.^[4]

In 1794, a fur trading post was built on the Peace River at Fort St. John; it was the first non-native settlement on the British Columbia mainland.

The rich soils of the Peace River valley in Alberta have been producing wheat crops since the late 19th century. The Peace River region is also an important centre of oil and natural gas production. There are also pulp and paper plants along the river in British Columbia.

Geography

Course

This river is 1,923 km long (from the head of Finlay River to Lake Athabasca). It drains an area of approximately 302,500 km².^[5] At Peace Point, where it drains in the Slave River, it has an annual discharge of 2161 m³/s or 68,200,000 dam³/a.^[6]

A large man-made lake, Williston Lake, has been formed on the upper river by the construction of the W. A. C. Bennett Dam for hydroelectric power generation. The river then flows into Dinosaur Lake, which serves as a reservoir for the Peace Canyon Dam. After the dams, the river flows east into Alberta and then continues north and east into the Peace-Athabasca Delta in Wood Buffalo National Park, at the western end of Lake Athabasca. Water from the delta flows into the Slave River east of Peace Point and reaches the Arctic Ocean via the Great Slave Lake and Mackenzie River.
