41-652: Alouette Lake , originally Lillooet Lake and not to be confused with the lake of that name farther north, is a lake and reservoir in Maple Ridge , British Columbia , Canada. It is at the southeastern foot of the mountain group known as the Golden Ears and is about 16 km in length on a northeast–southwest axis. It, and the Alouette River (formerly the Lillooet River), were renamed in 1914 to avoid confusion with
82-664: A navigable stream". His trip down the river convinced him that Fort Langley could not replace Fort Vancouver as the company's main depot on the Pacific coast. Much of British Columbia's history has been bound to the Fraser, partly because it was the essential route between the Interior and the Lower Coast after the loss of the lands south of the 49th Parallel with the Oregon Treaty of 1846. It
123-650: A regional position within the Canadian Heraldic Authority is named after the river. The Fraser River is known for the fishing of white sturgeon , all five species of Pacific salmon ( chinook , coho , chum , pink , sockeye ), as well as steelhead trout . The Fraser River is also the largest producer of salmon in Canada. A typical white sturgeon catch can average about 500 pounds (230 kg). A white sturgeon weighing an estimated 500 kilograms (1,100 lb) and measuring 3.76 metres (12 ft 4 in)
164-689: A short dam lifespan, but mostly because of strong opposition from fisheries and other environmental concerns. In 1858, the Fraser River and surrounding areas were occupied when the gold rush came to the Fraser Canyon and the Fraser River. It is also a popular fishing location for residents of the Lower Mainland. The delta of the river, especially in the Boundary Bay area, is an important stopover location for migrating shorebirds . The Fraser Herald ,
205-442: A significant spring freshet , primarily impacting regions around Prince George , Kamloops , Hope and Surrey . Due to record snowpacks on the mountains in the Fraser River catch basin which began melting, combined with heavy rainfall, water levels on the Fraser River rose in 2007 to a level not reached since 1972. Low-lying land in areas upriver such as Prince George suffered minor flooding. Evacuation alerts were given for
246-573: Is 11.5 km (7 mi) along the upper reaches of the South Alouette River . A 1,067 metres (3,501 ft) long tunnel connects Alouette Lake and Stave Lake. At the end of the tunnel is a penstock which feeds the small Alouette Powerhouse , an 8 MW power station operated by BC Hydro , which lies midway along the west shore of Stave Lake . 49°22′16″N 122°18′47″W / 49.37111°N 122.31306°W / 49.37111; -122.31306 ( Alouette Power Station ) There
287-574: Is a lake in British Columbia , Canada about 25 km in length and about 21 km (8.1 sq mi) in area. It is about 95 km downstream from the source of the Lillooet River , which resumes its course after leaving Little Lillooet Lake, aka Tenas Lake ( tenass in the Chinook Jargon means little ). Immediately adjacent to the mouth of the upper Lillooet River is the mouth of
328-686: Is joined by the Bridge and Seton Rivers at the town of Lillooet , then by the Thompson River at Lytton , where it proceeds south until it is approximately 64 kilometres (40 mi) north of the 49th parallel , which is Canada's border with the United States . From Lytton southwards it runs through a progressively deeper canyon between the Lillooet Ranges of the Coast Mountains on its west and
369-459: Is named Queensborough and is part of the City of New Westminster. Also in the lowermost Fraser, among other smaller islands, is Annacis Island , an important industrial and port area, which lies to the southeast of the eastern end of Lulu Island. Other notable islands in the lower Fraser are Barnston Island , Matsqui Island , Nicomen Island and Sea Bird Island . Other islands lie on the outer side of
410-428: Is no powerhouse at the dam, however, as the point of the reservoir is to feed the tunnel through the flank of the ridge between Mounts Crickmer and Robie Reid . A former railway grade leading to the dam along the river was also used as a logging railway. A large public beach, picnic site and campground that are part of the provincial park are located on the lake's western shore. Lillooet Lake Lillooet Lake
451-595: Is part of the Fraser Lowland and was formed also by sediment deposited from the Fraser, though most of the county is not in the Fraser drainage basin. Similar to the Columbia River Gorge east of Portland, Oregon , the Fraser exploits a topographic cleft between two mountain ranges separating a more continental climate (in this case, that of the British Columbia Interior ) from a milder climate near

Hell's Gate , located immediately downstream of the town of Boston Bar , is a famous portion of the canyon where the walls narrow dramatically, forcing the entire volume of the river through a gap only 35 metres (115 feet) wide. An aerial tramway takes visitors out over the river. Hells Gate is visible from Trans-Canada Highway 1 about 2 km (1.2 mi) south of
574-626: The District of Mission due to the rectangular shape of that district's boundary. North of the portion of the lake that is in Mission, the rest of its northern end is not in either municipality. Originally only 2 km in length, the lake was considerably expanded by the 1928 construction of the Alouette Dam at 49°17′10″N 122°29′12″W / 49.28611°N 122.48667°W / 49.28611; -122.48667 ( Alouette Dam ) , which

Simpson journeyed down the river and through the Fraser Canyon and afterwards wrote "I should consider the passage down, to be certain Death, in nine attempts out of Ten. I shall therefore no longer talk about it as
656-579: The Lower Mainland ( Fraser Valley and Metro Vancouver ) occurred in 1894. With no protection against the rising waters of the Fraser River, Fraser Valley and Metro Vancouver communities from Chilliwack downstream were inundated with water. In the 1894 floods, the water mark at Mission reached 7.85 metres (25.75 ft). After the 1894 flood, a dyking system was constructed throughout the Fraser Valley. The dyking and drainage projects greatly improved
697-526: The Mount Robson Provincial Park , to Steveston in Vancouver at the river mouth. With an average flow at the mouth of about 3,475 cubic metres per second (122,700 cu ft/s), the Fraser is the largest river by discharge flowing into the Pacific seaboard of Canada and the fifth largest in the country. The average flow is highly seasonal; summer discharge rates can be ten times larger than
738-720: The Rocky Mountain Trench and the Robson Valley near Valemount . After running northwest past 54° north, it makes a sharp turn to the south at Giscome Portage , meeting the Nechako River at the city of Prince George , then continues south, progressively cutting deeper into the Fraser Plateau to form the Fraser Canyon from roughly the confluence of the Chilcotin River , near the city of Williams Lake , southwards. It

The estuary at the river's mouth is a site of hemispheric importance in the Western Hemisphere Shorebird Reserve Network . The Water Survey of Canada currently operates 17 gauge stations that measure discharge and water level along the majority of the mainstem from Red Pass just downstream of Moose Lake in
820-514: The Strait of Georgia just south of the City of Vancouver . The river's annual discharge at its mouth is 112 cubic kilometres (27 cu mi) or 3,550 cubic metres per second (125,000 cu ft/s), and each year it discharges about 20 million tons of sediment into the ocean. The river is named after Simon Fraser , who led an expedition in 1808 on behalf of the North West Company from
861-577: The North Arm, which is the southern boundary of the City of Vancouver , and the South Arm, which divides the City of Richmond from the City of Delta to the south. Richmond is on the largest island in the Fraser, Lulu Island and also on Sea Island , which is the location of Vancouver International Airport , where the Middle Arm branches off to the south from the North Arm. The far eastern end of Lulu Island

#1732837402955902-575: The busy freight and passenger traffic in those days. The best-known and largest of these was the SS Prince of Wales , whose wreckage was visible on the shores of the lake near Mount Currie for many years. Fraser River The Fraser River ( / ˈ f r eɪ z ər / ) is the longest river within British Columbia , Canada, rising at Fraser Pass near Blackrock Mountain in the Rocky Mountains and flowing for 1,375 kilometres (854 mi), into
943-529: The coast. When an Arctic high-pressure area moves into the British Columbia Interior and a relatively low-pressure area builds over the general Puget Sound and Strait of Georgia region, the cold Arctic air accelerates southwest through the Fraser Canyon . These outflow winds can gust up to 97 to 129 kilometres per hour (60 to 80 mph) and have at times exceeded 160 kilometres per hour (100 mph). Such winds frequently reach Bellingham and
984-408: The estuary, most notably Westham Island , a wildfowl preserve, and Iona Island , the location of the main sewage plant for the City of Vancouver. After 100 kilometres (about 60 mi), the Fraser forms a delta where it empties into the Strait of Georgia between the mainland and Vancouver Island . The lands south of the City of Vancouver , including the cities of Richmond and Delta , sit on
1025-469: The first Europeans to find and enter it. The existence of the river, but not its location, had been deduced during the 1791 voyage of José María Narváez , under Francisco de Eliza . The upper reaches of the Fraser River were first explored by Sir Alexander Mackenzie in 1793, and fully traced by Simon Fraser in 1808, who confirmed that it was not connected with the Columbia River . The lower Fraser
1066-627: The flat flood plain . The islands of the delta include Iona Island, Sea Island, Lulu Island, Annacis Island, and a number of smaller islands. While the vast majority of the river's drainage basin lies within British Columbia, a small portion in the drainage basin lies across the international border in Washington in the United States, namely the upper reaches of the tributary Chilliwack and Sumas rivers. Most of lowland Whatcom County, Washington
1107-517: The flood problems, but over time, the dykes were allowed to fall into disrepair and became overgrown with brush and trees. With some dykes constructed of a wooden frame, they gave way in 1948 in several locations, marking the second disastrous flood. Flooding since 1948 has been minor in comparison. 1948 saw massive flooding in Chilliwack and other areas along the Fraser River. The high-water mark at Mission rose to 7.5 metres (24.7 ft). The peak flow
1148-551: The flow during the winter. The Fraser's highest recorded flow, in June 1894, is estimated to have been 17,000 cubic metres per second (600,000 cu ft/s) at Hope . It was calculated using high-water marks near the hydrometric station at Hope and various statistical methods. In 1948 the Fraser River Board adopted the estimate for the 1894 flood. It remains the value specified by regulatory agencies for all flood control work on
1189-539: The larger river and lake farther north, with "Alouette", the French word for " lark ", being chosen as being melodious and reminiscent of the original name in tone. Most of the basin of Alouette Lake has never been logged and its north flank is protected as part of Golden Ears Provincial Park (formerly part of Garibaldi Provincial Park until that park's division). A small portion of the lake and its largely inaccessible northwestern shore, near its narrows, are actually part of
1230-707: The mountain ranges of Garibaldi Provincial Park overlook Lillooet Lake from the west, while to the east are the northern reaches of the Lillooet Ranges which lie between the Lillooet-Harrison drainage and the Fraser River . Lillooet Lake was part of the "Lakes Route" or Douglas Road , once if only briefly the principal route between the Coast and the Interior during the days of the Fraser Canyon Gold Rush . Several steamers and innumerable smaller watercraft served
1271-437: The poorly maintained dyke systems failed to contain the water. At the height of the 1948 flood, 200 square kilometres (50,000 acres) stood under water. Dykes broke at Agassiz, Chiliwack, Nicomen Island, Glen Valley and Matsqui. When the flood waters receded a month later, 16,000 people had been evacuated, with damages totaling $ 20 million, about $ 225 million in 2020 dollars. Major flooding occurred once again in 1972 due to

1312-476: The river was designated as a Canadian Heritage River for its natural and human heritage. It remains the longest river with that designation. The Fraser is heavily exploited by human activities, especially in its lower reaches. Its banks are rich farmland, its water is used by pulp mills , and a few dams on some tributaries provide hydroelectric power . The main flow of the Fraser has never been dammed partly because its high level of sediment flows would result in
1353-585: The river, not dissimilar to the Dakelh name, is ʔElhdaqox , meaning Sturgeon ( ʔElhda-chugh ) River ( Yeqox ) . The Fraser drains a 220,000-square-kilometre (85,000 sq mi) area. Its source is a dripping spring at Fraser Pass in the Canadian Rocky Mountains near the border with Alberta . The river then flows north to the Yellowhead Highway and west past Mount Robson to

The river's name in the Halqemeylem (Upriver Halkomelem) language is Sto:lo , often seen archaically as Staulo , and has been adopted by the Halkomelem-speaking peoples of the Lower Mainland as their collective name, Sto:lo . The river's name in the Dakelh language is Lhtakoh . The Tsilhqot'in name for
1476-760: The tramway. Simon Fraser was forced to portage the gorge on his trip through the canyon in June 1808. At Yale , at the head of navigation on the river, the canyon opens up and the river widens, though without much adjoining lowland until Hope , where the river then turns west and southwest into the Fraser Valley , a lush lowland valley, and runs past Chilliwack and the confluence of the Harrison and Sumas Rivers , bending northwest at Abbotsford and Mission . The Fraser then flows past Maple Ridge , Pitt Meadows , Port Coquitlam , and north Surrey . It turns southwest again just east of New Westminster , where it splits into
1517-454: Was about 15,600 cubic meters per second. Cool temperatures in March, April, and early May had delayed the melting of the heavy snowpack that had accumulated over the winter season. Several days of hot weather and warm rains over the holiday weekend in late May hastened the thawing of the snowpack. Rivers and streams quickly swelled with spring runoff, reaching heights surpassed only in 1894. Finally,
