History of the Fraser River

Years before the Europeans discovered the Fraser River, it was inhabited by the aboriginal peoples of British Columbia. They traded with each other by traveling the rivers and trails and had various paths that connected the interior of British Columbia to the coast.

The Fraser River was first explored by the Europeans on June 14, 1792, by the Spanish explorers Dionisio Alcalá Galiano and Cayetano. They only discovered the northern arm of the Fraser River. During an earlier expedition by José María Narváez in 1791, the existence of the river was known, but the location was not found.

In 1793, Sir Alexander Mackenzie navigated the upper reaches of the river, but it was more fully explored by Simon Fraser in 1808. Further exploration continued as George Simpson came to the river in 1828 to decide whether Fort Langley would be adequate as the Hudson Bay Company’s main Pacific depot. After further examination, Fort Vancouver still remained the main headquarters for the company, but this allowed the establishment of Fort Langley.

Most of British Columbia’s history is linked to the Fraser River because it was an important and essential route between the Interior and the Coast. In 1856, James Huston discovered gold near Fort Kamloops. This triggered the search for gold from the Thompson River to the Fraser River, and eventually the first big gold discovery was made south of Yale. Following the miners from the gold rush, there was an influx of businessmen and merchants who brought their families to settle in this land. This started the formation of different communities and towns, bringing civilization to British Columbia.

Paddlewheelers, mules, and walking were means of transportation for the communities before 1861. Soon after, the Royal Engineers started the development of “the wagon road” to the Cariboo. When this 619 km road was opened, wagons and stage coaches used it immediately. The modernization of the transportation system was essential for Canada to become one nation. This was made possible under the governance of Canada’s first Prime Minister, Sir John A. Macdonald. The Canadian Pacific Railway (CPR) route in B.C. was built through the Rocky Mountains, the interior plateau and all along the Thompson and Fraser Rivers. It eventually led to the coast through Vancouver.

The historical significance of the Fraser River, and its importance in the development of the province of British Columbia, has garnered it the title of a Canadian Heritage River.

Watershed Facts

Mining, manufacturing, logging, pulp and paper making, farming, and energy industries have lined the banks of the Fraser and have fed the region’s development. Consequent of this activity and loosely enforced environmental regulations, or inadequate statutes, the Fraser suffers from a wide range of pollutants, including heavy metals, excessive nutrients, bacteria, polychlorinated biphenyls (PCBs), and dioxins. In addition to the industrial stresses exerted on the region, new development pressures metastasize as the vibrant Vancouver region draws more residents and more economic activity. The Greater Vancouver Regional District now houses more than 2.1 million people. It is expected that in the coming 20 years the population will increase by another 50%. This growth has detrimental consequences on the watershed due to both the development of surfaces, which exacerbates storm water runoff and combined sewerage outfalls, and the increased demands upon already inadequate sewage treatment infrastructures.

Mouth: Fraser River Delta, Strait of Georgia

Length: The Fraser River is tenth longest river in Canada, and the longest in British Columbia, at 1,375 km (854 Miles), from source to mouth.

Drainage basin area (watershed): The Fraser Basin contains the Fraser River and numerous tributaries, including the Willow River, Quesnel River, Thompson River, Williams Lake River, Coquihalla River, Vedder River, McGregor River, Nechako River, West Road River, Chilcotin River, Bridge River, Harrison River, and the Stave River. The entire watershed drains to an area of 220,000 km² (85,000 sq mi).

Discharge rate at the River mouth: The Fraser River flows at an average rate of around 3550 m3/second (or 112km3 per year) and dumps up to 20 million tonnes of sediment at its mouth in the Fraser Basin Delta.

Ecological Significance

The Fraser River and its tributaries provide a habitat for a variety of plant and animal species. Vegetation adjacent to the river consists of a variety of conifer species such as White Spruce, Lodgepole Pine, and Douglas Fir. The river hosts a wide variety of marine and freshwater vertebrate species. Included in this, and found in mainly the estuarine parts of river, are six main salmonid species: pink, chum, coho, sockeye, and Chinook salmon — and rainbow trout. Many marine species exist, such as starry flounder, pearmouth chub , redside shine and stickleback.

The Fraser Delta also provides a feeding and breeding habitat for migratory birds and has been recognised as a globally important centre of biodiversity.

Further upstream are species such as green sturgeon, coastal cutthroat trout, white sucker, pygmy whitefish, and chum salmon. The Fraser River is extremely important as it provides a spawning habitat for the pink Chinook and chum Pacific salmon species. The Fraser Delta, the largest estuary on the Pacific Coast of Canada, hosts the Pacific Northwest’s most important salmon runs in North America.

Recreation

The Fraser River has a wide range of recreational opportunities due to its accessibility and diversity. The riverhead is in the Rocky Mountains, and there it provides a haven for canoeing, kayaking, and whitewater rafting enthusiasts. As it makes its way down through the valley, the river provides opportunities for fishing and boating. Close to the community of Lytton, the Fraser Canyon attracts a large number of tourists. There are viewpoints, parks, trails, and an aerial tram that can take sightseers across the Fraser River. Other activities that take place in the basin include backpacking, skiing, snowboarding, and hiking. At the delta mouth of the river in the Lower Fraser valley, there are a number of recreational opportunities including walking, bird watching, picnicking, fishing and boating.

Declining Fish Populations

Known as one of the world’s most important salmon rivers, the “Mighty” Fraser River is also home to hundreds of invaluable species of flora and fauna. Recent salmon spawning migrations have been astonishingly low with many factors thought to be at play, not the least of which is habitat loss and pollution resulting from resource-based economic activities such as logging, mining, hydroelectric development, and agriculture.

The region faces a number of challenges imposed by industries old and new, coupled with the pressures of rapid urban development. Decades of heavy resource extraction and high pollution loads threaten to undermine the rich biodiversity that underpinned the success of the Fraser River Watershed and Vancouver in the first place. Salmon fisheries are depleted, and the future viability of mega fauna like raptors and Orca whales is jeopardized – signifying deeper systemic problems.

Just in the last few years, the declining fish populations have become more worrisome, but in 2009 there was a crisis in the sockeye salmon returns for the summer. Anticipated returns were high, but actual returns, according to the Department of Fisheries and Oceans, were 9-11 million short. This isn’t because of late migrations runs, according to the department, but because the fish died sometime during migration. More studies are underway to determine this loss, but many are speculating some or all of the following to play a role: sea lice and fish farms, over-fishing at sea, global warming, and pollution.
