What is The Longest Free Flowing River in the US?

The territory of the United States has colossal reserves of fresh water, concentrated in lakes and rivers, covering an area of almost a quarter of a million square meters (km2).

All of them are distinguished by dissimilar origins, lengths, and natural features, and they play a serious role in the economic life of the country.

Many reservoirs attract the attention of tourists and artists who have dedicated their works to them.

The largest rivers in America occupy the first lines of the ranking of the greatest water streams on the planet.

America’s Largest and Most Important Rivers


In total, there are approximately 250 thousand rivers in the United States; their length is more than 5 million kilometers.

They are distinguished by a variety of origins—glacial or tectonic.

They flow through both flat and mountainous areas. Most of them are mixed rivers.

The geographical position of the United States of America favors the formation of diverse streams and basins.

North America’s total annual flow is 6.5 thousand kilometers.

It is larger than the total drainage of Africa, Australia, and Antarctica, and in terms of the amount of its water reserves, it is second only to South America and Eurasia.

However, it is not uniformly distributed over the surface.

Most regions of the United States, due to the uneven distribution of resources, lack fresh natural water suitable for drinking.

In some regions of the country, its consumption is almost equal to the natural river runoff.

The largest and most famous rivers in the United States are known to all.

This is Missouri, Mississippi, and Colorado.

The waters of these rivers flow through several states.

The rivers in the north of the country are famous in many novels and films about the Gold Rush.

Tourists go to them to appreciate the hard work of prospectors. Many rivers flow through the territories of national reserves and parks.

What is the longest free-flowing river in the US?

The Yellowstone River in Montana is the longest free-flowing river in the USA.

It flows through three US states and passes through Yellowstone National Park.

The source of the river is in the Rocky Mountains, in dense pine forests.

In the upper reaches, the river forms canyons up to 360 meters deep and waterfalls up to 94 meters high.

The nature on the banks of the river is known among tourists due to its picturesque landscapes.

The name of the river comes from the Indian: “river of yellow stones.”

Is the Mississippi a free-flowing river?

The Mississippi is the longest free-flowing river in the USA.

It is also the largest river in North America, the third longest river in the world (3770 km) after the Nile and the Amazon, and is considered the country’s primary water artery.

In the language of the indigenous people, the name of this river means “big river.”

The Mississippi River originates in Minnesota at an elevation of 530 meters above sea level from Lake Itasca in Itasca Park or from Nicolette Creek, which flows into it.

The reservoir is considered the pride of the country.

The Mississippi flows through 10 US states, and its basin includes the territories of 31 states where the Mississippi River is located, and the borders of many of them run along the channel.

The river flow begins in an area with heavy rainfall and is distinguished by a measured flow, despite the short-term freezing in winter.

The current in the upper reaches of the river passes through rocky terrain.

The largest rift is atSt. Anthony Falls, near the city of Minneapolis.

So the current is rough. Further, the channel is more gentle but still has high slopes.

Spring on the Mississippi is when water levels are at their highest.

Severe flooding is not uncommon, breaking through dams and inundating low-lying areas and agricultural land. As a result, the Mississippi River Valley is one of the most fertile regions of the country.

Is the Yellowstone a wild river?

Yes, the Yellowstone River is considered a wild river.

It means that this river is least affected by man; that is, it does not have dams, hydroelectric power plants, or other structures that change the course or direction of the flow.

The Yellowstone River is a right-hand tributary of the Missouri.

It originates in the Rocky Mountains and flows through the states of Montana, Wyoming, and North Dakota.

Its length is more than a thousand kilometers.

The name of the river, and accordingly the park, comes from the Indian “river of yellow stones.” This is how you can describe the canyon that forms the river and its colorful banks.

To be convinced of this, it is enough to come to the canyon (the Grand Canyon of Yellowstone) and look at the color of the rocks that form the green Yellowstone River.

There are several waterfalls on the Yellowstone River.

On each of these rivers—the Madison, Gibbon, and Yellowstone—waterfalls have formed, spectacular and beautiful.

However, the most beautiful waterfall in Yellowstone Park is located on a very small river, or more precisely, on a stream called Lava. This is Ondine Falls.

This national park contains 45 named waterfalls and hundreds more that are unnamed.

But what about the Amazon?

This river has the largest basin in the world and  is located in South America.

Amazon—the most abundant river in the world.
It is located in South America, begins in the Andes in Peru, and flows into the Atlantic Ocean.

It flows almost along the equator, that is, in a zone with a tropical climate, so frequent rains constantly fill it.

The river is deep and navigable; river transport is well developed; even ocean liners rise nearly a thousand nautical miles upstream.

The Amazonian lowland is covered with evergreen forest, where there are more than a million species of animals and plants.
Facts about Amazon

  1. A channel with a length of more than 7000 km;
  2. Pool area of about 7,000 square kilometers and a delta of 100 square kilometers;
  3. Per year, the river carries away about 7,000 cubic meters of water from the continent (one sixth of all fresh water entering the world’s oceans).
