The Peace River ({{langx|fr|links=no|rivière de la Paix}}) is a {{convert|1923|km|mi|adj=mid|-long}} river in Canada that originates in the Rocky Mountains of northern British Columbia and flows to the northeast through northern Alberta. The Peace River joins the Athabasca River in the Peace-Athabasca Delta to form the Slave River, a tributary of the Mackenzie River. The Finlay River, the main headwater of the Peace River, is regarded as the ultimate source of the Mackenzie River. The combined Finlay–Peace–Slave–Mackenzie river system is the 13th longest river system in the world.

History

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.[http://www.britannica.com/eb/article-9058854 "Peace River"], Encyclopædia Britannica, 2006. Retrieved September 12, 2006, from Encyclopædia Britannica Premium Service Mackenzie referred to the river as Unjegah, from the Dane-zaa meaning "large river."

The decades of hostilities between the Dane-zaa and the Cree, (in which the Cree dominated the Dane-zaa), ended in 1781 when a smallpox epidemic decimated the Cree. The Treaty of the Peace was celebrated by the smoking of a ceremonial pipe. The treaty made the Peace River a border, with the Dane-zaa to the North and the Cree to the South.Coutts, M. E. (1958).

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

The rich soils of the Peace River valley in Alberta have been producing wheat crops since the late 19th century. In the early 21st century, the BC Grain Producers Association was researching the productivity of wheat and other grain crops near Dawson Creek.{{cite web |title=BC Peace Region 2018 Field Crop Variety Performance |url=http://bcgrain.com/wp-content/uploads/2019/01/2018-Book.pdf |website=bcgrain.com |publisher=BC Grain Producers Association}} 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 Alberta and British Columbia.

|quote = The brothers built a fleet of small primitive steamers, extending by 1903 to the waters of the Peace above the Vermilion Chutes. In that year the pint—sized sternwheeler St. Charles began to work the 526 mile stretch from Fort Vermilion to Hudson’s Hope, carrying lumber and supplies for the Mission at Fort St. John in British Columbia, as well as goods for the Northwest Mounted Police.

The first steam-powered vessel to navigate the Peace River was the Grahame, a Hudson's Bay Company vessel built at Fort Chipewyan, on Lake Athabasca. Brothers of the Oblate Order of Mary Immaculate built the St. Charles to navigate the upper reaches of the River, from Fort Vermilion to Hudson's Hope. Approximately a dozen vessels were to navigate the river. Most of the early vessels were wood-burning steamships, fueled by wood cut from the river's shore. The last cargo vessel was the Watson's Lake, retired in 1952.

= Hydroelectric development =

Hydroelectric development began on the Peace River in 1968 and continues to be an important source of renewable energy for British Columbia's main electricity provider, BC Hydro. The river’s first dam, the W. A. C. Bennett Dam, was completed in 1968 and is British Columbia's largest dam and the third-largest hydroelectric facility in Canada. It supplies over 30% of British Columbia's total power demand. Engineers took advantage of the W. A. C. Bennet Dam's large reservoir storage to further develop the river with the Peace Canyon Dam opened in 1980.{{Cite web|title=Peace Region|url=https://www.bchydro.com/energy-in-bc/operations/our-facilities/peace.html|website=BC Hydro}} The Site C dam is under construction and scheduled to be finished in 2025;{{update after|2025}} it will further benefit from the upstream dams and generate additional electrical capacity to meet British Columbia's growing demand for green energy and reduce the carbon footprint of residents.{{Cite web|title=About the Site C project|url=https://sitecproject.com/about-site-c/project-overview|website=Site C Clean Energy Project}} {{As of|2020}} both the Alberta government and private producers were studying the possibility of hydroelectric development on the Alberta stretch of the river with one run-of-the-river project currently being proposed.{{Cite web|date=2020|title=Home|url=http://www.amiskhydro.com/home-.html|website=Amisk Hydro Project}}

A large man-made lake, Williston Lake, has been formed on the upper reaches by the construction of the W. A. C. Bennett Dam for hydroelectric power generation. Prior to its flooding, the confluence of the Finlay and Parsnip Rivers at Finlay Forks was distinct. A half mile east of that location were the half-mile long Finlay Rapids and a further seven miles east is the Peace Pass, which separates the Muskwa Ranges and the Hart Ranges of the Canadian Rockies.

The only river cutting completely through the Rockies,Fort George Tribune, 20 Jun 1914Prince George Citizen, 26 Sep 1916 it nowadays flows into Dinosaur Lake, 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.
