77-687: The plan for the Moisie river aquatic reserve was officially announced by the Government of Quebec in February 2003. It would be the first aquatic reserve in Quebec, and the Moisie would become the first watercourse to the fully protected against any form of industrial exploitation. Measured by watershed, the Moisie would be the second largest protected river in southern Canada, after the Fraser River . The reserve includes

154-484: A sink , which may be a permanent lake, a dry lake , or a point where surface water is lost underground . Drainage basins are similar but not identical to hydrologic units , which are drainage areas delineated so as to nest into a multi-level hierarchical drainage system . Hydrologic units are defined to allow multiple inlets, outlets, or sinks. In a strict sense, all drainage basins are hydrologic units but not all hydrologic units are drainage basins. About 48.71% of

231-414: A watershed , though in other English-speaking places, "watershed" is used only in its original sense, that of the drainage divide line. A drainage basin's boundaries are determined by watershed delineation , a common task in environmental engineering and science. In a closed drainage basin, or endorheic basin , rather than flowing to the ocean, water converges toward the interior of the basin, known as

308-660: A corridor 6 to 30 kilometres (3.7 to 18.6 mi) wide, including 115 kilometres (71 mi) of the Aux Pékans River. The proposed aquatic reserve is in the Grenville Province of the Canadian Shield , in the foothills of a mountain range formed almost 1,000 million years ago, with high and low hills, mounds and hummocks. The bedrock is mostly gneiss and paragneiss , with some marble upstream, and small pockets of anorthosite and charnockite downstream. The surface

385-449: A drainage basin, and there are different ways to interpret that data. In the unlikely event that the gauges are many and evenly distributed over an area of uniform precipitation, using the arithmetic mean method will give good results. In the Thiessen polygon method, the drainage basin is divided into polygons with the rain gauge in the middle of each polygon assumed to be representative for

462-540: A drainage boundary is referred to as watershed delineation . Finding the area and extent of a drainage basin is an important step in many areas of science and engineering. Most of the water that discharges from the basin outlet originated as precipitation falling on the basin. A portion of the water that enters the groundwater system beneath the drainage basin may flow towards the outlet of another drainage basin because groundwater flow directions do not always match those of their overlying drainage network. Measurement of

539-584: A longer growing period further south. A map of the Ecological regions of Quebec shows the Aux Pékans River rising to the northwest of Fermont just west of the Spruce/lichen domain of the boreal zone. The Moisie itself rises and flows for most of its length through the eastern spruce/moss domain of the boreal zone. In the north, heath covers the steeper valley slopes. About a third of the proposed reserve

616-664: 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

693-650: 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)

770-689: 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 ,

847-442: 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

924-564: A single point, such as a river mouth , or flows into another body of water , such as a lake or ocean . A basin is separated from adjacent basins by a perimeter, the drainage divide , made up of a succession of elevated features, such as ridges and hills . A basin may consist of smaller basins that merge at river confluences , forming a hierarchical pattern . Other terms for a drainage basin are catchment area , catchment basin , drainage area , river basin , water basin , and impluvium . In North America, they are commonly called

1001-561: Is covered by a thin layer of glacial till upstream. Further down the surface is mostly covered in rock and peat. The bed of the Moisie river is composed of glaciofluvial sand and gravel. The highest elevation in the proposed reserve is 991 metres (3,251 ft), falling to 8 metres (26 ft) near the coast. The average elevation is 437 metres (1,434 ft). The Moisie river rises in Ménistouc lake at an elevation of 520 metres (1,710 ft) and flows south for 363 kilometres (226 mi) to

1078-404: Is covered by forest. This mainly consists of stands of mature softwood. The most common species is black spruce ( Picea mariana ), often growing with balsam fir ( Abies balsamea ). Sandy terraces may hold jack pine ( Pinus banksiana ). There are a few mixed stands, in which the most common hardwood is paper birch ( Betula papyrifera ). Near its mouth, south of the reserve, the river enters

1155-686: 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

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

1309-595: 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

1386-480: Is referred to as " watershed management ". In Brazil , the National Policy of Water Resources, regulated by Act n° 9.433 of 1997, establishes the drainage basin as the territorial division of Brazilian water management. When a river basin crosses at least one political border, either a border within a nation or an international boundary, it is identified as a transboundary river . Management of such basins becomes

1463-600: Is the Dead Sea . Drainage basins have been historically important for determining territorial boundaries, particularly in regions where trade by water has been important. For example, the English crown gave the Hudson's Bay Company a monopoly on the fur trade in the entire Hudson Bay basin, an area called Rupert's Land . Bioregional political organization today includes agreements of states (e.g., international treaties and, within

1540-682: The African Great Lakes , the interiors of Australia and the Arabian Peninsula , and parts in Mexico and the Andes . Some of these, such as the Great Basin, are not single drainage basins but collections of separate, adjacent closed basins. In endorheic bodies of water where evaporation is the primary means of water loss, the water is typically more saline than the oceans. An extreme example of this

1617-629: The Aux Pékans and Carheil rivers, tributaries of the Moisie that Hydro-Québec had been studying with a view to diverting them to the Sainte-Marguerite River basin to increase the energy that could be stored for the SM-3 plant. However, a commission of the Bureau of Public Hearings on the environment concluded that this was not economically justified, and could adversely affect the salmon population. In

The Indian Ocean 's drainage basin also comprises about 13% of Earth's land. It drains

2002-579: 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

2079-526: 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

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

2541-867: The Saint Lawrence Estuary. Its drainage basin covers 19,196 square kilometres (7,412 sq mi). It has nine tributaries that drain more than 300 square kilometres (120 sq mi). The largest are the Aux Pékans River in the north, draining 3,419 square kilometres (1,320 sq mi), and Nipissis River in the south, draining 4,196 square kilometres (1,620 sq mi). The river drops on average 1.4 metres per kilometre (7.4 ft/mi), with sections of rapids and waterfalls, and discharges 401 cubic metres per second (14,200 cu ft/s) on average of exceptionally clean water. Along most of its length it runs through deep gorges. The river flows through dramatic, unspoiled scenery and has not been dammed for hydroelectricity. It has great value as one of

Under the Natural Heritage Conservation Act, prohibited activities would include mining, and gas or petroleum development; exploration of underground resources that involves stripping, trenching, excavation or deforestation; forestry; industrial generation of hydroelectricity or other types of power; new vacation resorts; and earthwork, back-filling or construction work. Also, no activity would be allowed that would be likely to damage

2772-406: The basin, it can form tributaries that change the structure of the land. There are three different main types, which are affected by the rocks and ground underneath. Rock that is quick to erode forms dendritic patterns, and these are seen most often. The two other types of patterns that form are trellis patterns and rectangular patterns. Rain gauge data is used to measure total precipitation over

2849-618: The bed, banks or shore of any water body or stream in the reserve. The proposed Moisie river aquatic reserve is in the Côte-Nord region between 50°19' and 52°29' north and 65°58' and 67°33' west. The upstream portion is in the Caniapiscau Regional County Municipality and the downstream portion is in the Sept-Rivières Regional County Municipality . The river runs from north to south through

2926-529: 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

3003-542: The community, and several people asked for a referendum if an agreement in principle was signed. The Matimekosh – Lac-John Innu should also be involved, since their ancestors had used the river in the past. The goals are to conserve a representative river in the Manicouagan Reservoir Basin and Sainte-Marguerite River Plateau natural region, to protect the Atlantic salmon population, to protect biodiversity in

3080-430: The discharge of water from a basin may be made by a stream gauge located at the basin's outlet. Depending on the conditions of the drainage basin, as rainfall occurs some of it seeps directly into the ground. This water will either remain underground, slowly making its way downhill and eventually reaching the basin, or it will permeate deeper into the soil and consolidate into groundwater aquifers. As water flows through

3157-441: The drainage area is dependent on the soil type. Certain soil types such as sandy soils are very free-draining, and rainfall on sandy soil is likely to be absorbed by the ground. However, soils containing clay can be almost impermeable and therefore rainfall on clay soils will run off and contribute to flood volumes. After prolonged rainfall even free-draining soils can become saturated , meaning that any further rainfall will reach

3234-692: The drainage basin to the mouth, and may accumulate there, disturbing the natural mineral balance. This can cause eutrophication where plant growth is accelerated by the additional material. Because drainage basins are coherent entities in a hydrological sense, it has become common to manage water resources on the basis of individual basins. In the U.S. state of Minnesota , governmental entities that perform this function are called " watershed districts ". In New Zealand, they are called catchment boards. Comparable community groups based in Ontario, Canada, are called conservation authorities . In North America, this function

The five largest river basins (by area), from largest to smallest, are those of the Amazon (7 million km ), the Congo (4 million km ), the Nile (3.4 million km ), the Mississippi (3.22 million km ), and the Río de la Plata (3.17 million km ). The three rivers that drain

3388-407: The eastern fir/white birch domain of the boreal zone. The Moisie river is known as an Atlantic salmon ( Salmo salar ) river, with catches averaging 7 kilograms (15 lb) in weight. Many of the fish spawning on the river have spent several seasons at sea. Some return to spawn for several years in a row. Salmon fishing is allowed on the lower 170 kilometres (110 mi) of the Moisie River, and on

3465-404: The end the government decided in favor of protecting the two tributaries. In April 2018 it was reported that the negotiations between the Uashat-Maliotenam Council, the Department of Aboriginal Affairs and the Department of Forests, Wildlife and Parks on creating the aquatic reserve did not have the full support of the community. One of the councilors said the chief had not consulted enough with

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

3619-413: 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

3696-460: 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

3773-464: 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

3850-443: 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

3927-412: The greatest portion of western Sub-Saharan Africa , as well as Western Sahara and part of Morocco . The two major mediterranean seas of the world also flow to the Atlantic. The Caribbean Sea and Gulf of Mexico basin includes most of the U.S. interior between the Appalachian and Rocky Mountains , a small part of the Canadian provinces of Alberta and Saskatchewan , eastern Central America ,

With the water, they are transported towards the outlet of the basin, and can affect the ecological processes along the way as well as in the receiving water body . Modern use of artificial fertilizers , containing nitrogen (as nitrates ), phosphorus , and potassium , has affected the mouths of drainage basins. The minerals are carried by

4081-422: The ground at its terminus, the area can go by several names, such playa, salt flat, dry lake , or alkali sink . The largest endorheic basins are in Central Asia , including the Caspian Sea , the Aral Sea , and numerous smaller lakes. Other endorheic regions include the Great Basin in the United States, much of the Sahara Desert , the drainage basin of the Okavango River ( Kalahari Basin ), highlands near

The Mediterranean Sea basin, with the Black Sea , includes much of North Africa , east-central Africa (through the Nile River ), Southern , Central, and Eastern Europe , Turkey , and the coastal areas of Israel , Lebanon , and Syria . The Arctic Ocean drains most of Western Canada and Northern Canada east of

4235-415: The last remaining examples of untamed rivers on the North Shore. The area of the proposed reserve is in the Central Laurentian natural province, in the Manicouagan Reservoir Basin and the Sainte-Marguerite River Plateau natural regions. The climate is subarctic , subhumid in the north and south, and humid in the center. It is cold, with a short growing season in the north, and has a less severe climate with

4312-442: The low-lying areas not protected by dikes in the Lower Mainland . However, the water levels did not breach the dikes, and major flooding was averted. Major flooding occurred in November 2021 as part of the November 2021 Pacific Northwest floods . Tributaries are listed from the mouth of the Fraser and going up river. Drainage basin A drainage basin is an area of land in which all flowing surface water converges to

4389-409: The most water, from most to least, are the Amazon, Ganges , and Congo rivers. Endorheic basin are inland basins that do not drain to an ocean. Endorheic basins cover around 18% of the Earth's land. Some endorheic basins drain to an Endorheic lake or Inland sea . Many of these lakes are ephemeral or vary dramatically in size depending on climate and inflow. If water evaporates or infiltrates into

4466-437: 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

Nile Basin Initiative , OMVS for Senegal River , Mekong River Commission are a few examples of arrangements involving management of shared river basins. Management of shared drainage basins is also seen as a way to build lasting peaceful relationships among countries. The catchment is the most significant factor determining the amount or likelihood of flooding . Catchment factors are: topography , shape, size, soil type, and land use (paved or roofed areas). Catchment topography and shape determine

4774-461: The river rather than being absorbed by the ground. If the surface is impermeable the precipitation will create surface run-off which will lead to higher risk of flooding; if the ground is permeable, the precipitation will infiltrate the soil. Land use can contribute to the volume of water reaching the river, in a similar way to clay soils. For example, rainfall on roofs, pavements , and roads will be collected by rivers with almost no absorption into

4851-476: 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

4928-411: 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

Further studies and hydraulic models have estimated the maximum discharge of the Fraser River, at Hope during the 1894 flood, as within a range of about 16,000 to 18,000 cubic metres per second (570,000 to 640,000 cu ft/s). On June 14, 1792, the Spanish explorers Dionisio Alcalá Galiano and Cayetano Valdés entered and anchored in the North Arm of the Fraser River, becoming

5082-454: The south part of the Nipisso River. About 1,000 to 1,500 fish are caught each year, generating local economic benefits of about CDN$ 2 million. The population of Atlantic salmon is declining rapidly, both here and elsewhere. Two electrical power lines cross the south of the proposed reserve. Almost all the proposed reserve is within the Saguenay beaver reserve, where the Innu people of the Innu Takuaikan Uashat Mak Mani-Utenam first nation have

5159-418: The speed with which the runoff reaches a river. A long thin catchment will take longer to drain than a circular catchment. Size will help determine the amount of water reaching the river, as the larger the catchment the greater the potential for flooding. It is also determined on the basis of length and width of the drainage basin. Soil type will help determine how much water reaches the river. The runoff from

5236-415: The time taken for rain to reach the river, while catchment size, soil type, and development determine the amount of water to reach the river. Generally, topography plays a big part in how fast runoff will reach a river. Rain that falls in steep mountainous areas will reach the primary river in the drainage basin faster than flat or lightly sloping areas (e.g., > 1% gradient). Shape will contribute to

5313-477: The time taken for runoff water within a drainage basin to reach a lake, reservoir or outlet, assuming constant and uniform effective rainfall. Drainage basins are the principal hydrologic unit considered in fluvial geomorphology . A drainage basin is the source for water and sediment that moves from higher elevation through the river system to lower elevations as they reshape the channel forms. Drainage basins are important in ecology . As water flows over

The river mouth is on the north shore of the Estuary of Saint Lawrence about 25 kilometres (16 mi) east of the town of Sept-Îles, Quebec . The proposed reserve would cover 3,897.58 square kilometres (1,504.86 sq mi), following the main bed of the Moisie River from 37 kilometres (23 mi) to 358 kilometres (222 mi) from its mouth through

5544-692: The world's land drains to the Atlantic Ocean . In North America , surface water drains to the Atlantic via the Saint Lawrence River and Great Lakes basins, the Eastern Seaboard of the United States, the Canadian Maritimes , and most of Newfoundland and Labrador .
