US rivers: a brief description of the largest watercourses

The United States of America is a country that is very rich in fresh water. Large rivers of the United States and bring a lot of benefits for the state, as almost everywhere are navigable. The most famous reservoirs are the Great Lakes. They include several large lakes, which are connected by straits, as well as small water flows. The most significant and large rivers are Missouri, Colorado, Mississippi, Columbia.

USA

One of the most influential powers in the world is America. It also surpasses in size and population many states.

The US occupies the fourth place (9630 thousand sq. Km). It borders on Canada and Mexico.

Due to the length of the state, its relief is quite diverse. Here you can find both lowlands and mountain ranges. Each state has its own climatic features: it is not uncommon for both arctic frosts and tropical heat. The United States is conditionally divided into 4 time zones.

The population is divided into social classes, which differ in the level of life, education, income. Due to large-scale immigration in the United States live representatives of virtually all races and nations. The state language is not accepted here, but English became the most common.

The US is divided into 4 regions, and the state is also divided into so-called belts - areas that have similar living conditions, religion, traditions, etc.

Rivers of the USA

The nature of the United States of America can be spoken for a very long time, but we can not fail to mention water flows.

In New York, there is Susquehanna. Its water is very clean, which makes it possible to use it as a drinking water. However, coal mining can very strongly poison the water flow, which is why the government is developing a plan with which pollution will be minimized.

Virtually all rivers located in the United States, Very often are influenced by industry. For example, in the Bristol Bay, watercourses are constantly, for many years, suffering from mining.

Roanoke, the river in Virginia, like Susquehanna, has the purest waters. In addition, it has a uranium mine, the extraction of which can lead to terrible consequences.

In Illinois there is a Chicago watercourse, which is heavily polluted by sewage. It saves other US rivers from dirt, since it is the only haven for waste.

Salmon and salmon can be found in Yuba. It is a hydroelectric power station. Also, numerous dams were built on it, which became an obstacle to the migration of fish. However, if you do not build passages for aquatic animals, then salmon may be endangered.

Mississippi - the main river of the USA

The greatest water flow of both America and the world is the Mississippi. It is completely located in the States, but its pool covers a small area of Canada. It originates in Nicolett Creek, joins the Gulf of Mexico.

Mississippi is the longest river in the United States. Its length is more than 3500 km. Also due to its area in its pool are almost all states of the state. Basically the river has a southern current.

Missouri - the tributary of the Mississippi River

The Missouri River is considered to be the largest water stream in North America and the tributary of the River. Mississippi. The source is in the Rocky Mountains, which completely affects its characteristic current. It is worth noting that other major US rivers originate in this place. The length of Missouri is 3767 km. Thanks to this watercourse in the XIX century, the settlers moved to the west, thereby expanding the borders of the United States.

Peak development of shipping fell in the 30 years of the twentieth century. During 20 years, many dams and other structures were built, but at the present time one can observe a certain decline in the development of the river.

The main water artery of the country

Colombia occupies a leading position in the list of "Major US rivers". It is located in North America and flows not only through the States, but also through Canada. Its length is 2 thousand km.

It feeds on glacial waters. Due to the mountain nature of the current and the large volume of water, it creates ideal conditions for the operation of hydroelectric power stations. Totally there are 14 hydroelectric power stations on the water stream.

Navigation on the river developed quite difficult, as it had many shallows and rapids. However, in the twentieth century, the construction of numerous dams helped to fill the riverbed with enough water. It is this factor that made it possible to make a significant breakthrough in this area.

Colorado - deep river

In the southwest of the United States of America, the Colorado River flows. Its length is 2334 km. It flows into the Gulf of California. Almost the whole water flow basin is in the US, it is more than 600 thousand km ² . Colorado is widely used both in agriculture and for other household needs of the population. Earlier in the river there were about 50 species of fish. However, work to change the flow led to a decrease in their population. It is worth noting that 4 species are almost completely at the stage of extinction.

Colorado has a turbulent flow that attracts a large number of tourists. On its banks there are many national parks and forests, where you can have a good time and fully relax.

The rating "Major rivers of the United States", of course, is headed by Mississippi. Now, due to human activities, the state of the water flow is deteriorating, but the government still carries out a number of special events that slowly improve the ecology.
