What Is The Longest River In Canada

What Is The Longest River In Canada – The Maxie River is the longest river in Canada, measured from its mouth on the Beaufort Sea to the headwaters of the Finley River, a large mountain tributary. The first tree, a very short section of Makzi, is highlighted in dark blue.

Among the longest rivers in Canada are 47 streams less than 600 km (370 mi). For some rivers such as the Columbia, the LGH listed in the table below is only the main stem. In the case of others such as Mackzie, the main leg is LGHan and one or more upper streams, as already. Excluded from the list are rivers such as the Dauphin, a short lake connection between Manitoba and Winnipeg, with headwaters of 100 km (62 mi) or less. Also removed in rivers like the Mississippi, and the main product does not cross Canada although some of their passages.

Nine rivers on this list cross or create international boundaries. Four – Yukon, Columbia, Porcupine, and Kootai – started in Canada and sailed to the United States. Five went – Milk, PD d’Oreil, St. Lawrence, Red, and St. John – launched in the United States and they sailed to Canada. Of these, the Ware and the Cathay crossed international borders twice, the Ware departed and crossed the United States again, the Canadians departed and entered Canada a- again.

The water streams of these nine rivers flow in both countries; In addition, the dry basins of six others – Prosser, Assiniboine, South Saskatchewan, Saskatchewan, Nelson, and Winnipeg – have entered the United States, although their original trees were flowing across the country.

Sources report hydrological measurements with varying accuracy. Biologist and author Ruth Patrick, describing the record of the highest rivers, wrote that the data on discharge, drainage area and LGH differ greatly among the authors of their consulted works. “It seems,” he said, “that the wisest way is to look at the data tables in a way that shows the general condition of the rivers, and not to worry too much about the small differences (10-20% ) in figures.”

The primary source for the data in the table below is Atlas Canada; Other sources are as indicated. Discharge refers to flow into the mouth unless otherwise stated. It is U.S. States appear in italics. The abbreviations are as follows: “km” for “kilometer”, “mi” for “mile”, “s” for “second”, “m” for “metre”, and “ft” for “feet”.

The Mackenzie River in Canada, the longest in the country, flows out of Great Slave Lake, just north of the border between Alberta and the West Coast Territories. The river flows northwest, straight to the northern reaches of the Rocky Mountains before widening into a muddy lake-shaped delta. The delta flows into the Arctic Ocean through the Beaufort Sea.

This photo of the Mackenzie River Delta was taken by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite on August 4, 2005. It was the height of summer, and the area was the longest north melting. Hundreds of lakes pass through the green leaves of the tundra. Shades of blue indicate differences in water depth and clarity. The shallower or muddy the water, the lighter the blue.

The Mackenzie River itself is full of sediment, cutting a wide lavender-colored ribbon on the left side of the picture. A number of white sandbars appear along the river which can be seen here. A large section in the river near the top of the picture appears to be an oxbow lake. As the sediment moves along the channels in the loop, the flow will eventually be restricted and eventually cut off from the main channel entirely. The result is a semi-circular arched lake. Many arch lakes are visible in the larger part of the image.

Rivers have always played an important role in determining human settlement, providing habitat for fish, birds and other animals, and contributing to biodiversity. To better understand the principles, let’s take a trip down the Fraser River, which – at more than 1,370 km – is the longest river in British Columbia and the 10th.

The Fraser River begins its journey near the Fraser Pass on the BC/Alberta border. Here, what is known further down as a great river is only a trick. However, the river always washes its bedrock and carries the results of the destruction of the roof below. Therefore, it is possible that in thousands or even hundreds of thousands of years, non-flowing rivers can turn into rivers that flow in deeply incised valleys.

The health of the river ecosystems we depend on goes hand in hand with the climate, and it starts here at the source. Rivers are linked to air through precipitation and air temperature. Rising temperatures are causing river-fed ice and snow to melt earlier and faster, allowing less water to enter the river later in the year . Low water levels in late summer lead to higher than normal water temperatures, which can threaten the survival of salmon before they reach the spawning grounds. There are five species of salmon in the Fraser, associated with 10,000 years of First Nation history and culture and the cornerstone of a $300 million fishing industry on the river – so both the river’s ecology and economy suffer. Under climate change.

The land​​​​​​ that is covered by streams and rivers that flow into a larger river is called a “watershed”. Man-made barriers can disrupt the natural flow of water in wetlands. For example, Kenny Dam, built in the 1950s to power aluminum smelters west of Prince George in central BC, diverts two-thirds of the water in the Nechako area from Fraser River and into Western waters. . The coast on the one hand, aquatic life can suffer or die, and fish migration routes can be cut off when rivers are diverted or damaged, reducing downstream rivers or drying up. On the other hand, dams are important for hydropower and provide up to 86% of BC’s total energy supply.

The Fraser River watershed covers a quarter of BC (about the size of Great Britain), and includes half of BC’s farmland. The areas near the river are made of millions of years of deposited sediment, which makes the land fertile and ideal for agriculture. Unfortunately, these areas are also natural floodplains, putting homes and farms at risk of flooding. Therefore, when fertilizers are used for agriculture on the fields, these chemicals can enter rivers that flow freely and for long distances, where they star the fish, the sturgeon last white we had.
