The world’s population owes much of its success to river systems that provide water, transportation, and even protection in some cases. Some of these rivers are larger than others and discharge a great deal, but they vary in depth. A single river can range from a dozen feet in depth at one point to several hundred at another. Today, we’re going to look at the deepest rivers in the world, showing you that even the largest rivers are not always the deepest.  

How Are Rivers Made?

Rivers form when precipitation in areas with a higher elevation gathers to create a flow of water in the form of streams. Eventually, these streams collect into a larger body of water like a lake that serves as headwaters. In the case of the Mississippi River, Lake Itasca is considered the river’s source.

Then, the river continues its flow, gaining water from tributaries along the way. Eventually, the river reaches its outflow, also called the mouth, which is another river or the sea in most cases. Larger rivers tend to form in areas with a history of significant geological activity that aid in the formation of valleys and basins that lead to large river flows.

What Are the 10 Deepest Rivers in the World?

The deepest rivers in the world are found across several continents. Unsurprisingly, some of the deepest rivers are among the longest ones. We’re going to show you the depths, locations, and lengths of each of these rivers. By the time we’re finished, you’ll know all the deepest rivers in the world.

Keep in mind that these depths are not consistent throughout the river’s run. Instead, they are the deepest point found on the river.

10. Mississippi River

The Mississippi River is known as the second-longest river in the United States. This massive river bisects the United States starting in Minnesota and traveling down to New Orleans and reaching the Gulf of Mexico. This deepest part of the Mississippi River is 200ft deep, and that measurement occurs near the end of the river in Algiers Point.

9. Hudson River

The Hudson River is rather short compared to many of the others on this list. It runs from New York State until it reaches its outlet in the Upper New York Bay between Manhattan and Jersey City. The deep valley through which this river runs reaches a depth of 216ft! This river is one of the most important waterways in the U.S. for transportation and crossings.

8. St. Lawrence River

The St. Lawrence River is a river that flows from the Great Lakes in the United States to the Atlantic Ocean. This river flows northeast from Lake Ontario, forming a border between the U.S. and Canada, and has a mouth at the Gulf of St. Lawrence. The river is an important waterway for commercial purposes, and it has been the site of battles throughout history.

7. Yellow River

The Yellow River is one of the longest rivers in the entire world, and it’s known as one of the most important waterways in China. The abundance provided by this river allowed China’s civilization to flourish. Many hydroelectric dams have been built along the length of this river, and they help supply a tremendous amount of power to the nation.

From a historical and modern-day standpoint, this river is very significant as well as very deep, with a portion of the river measuring 262ft in depth!

6. Mekong River

The Mekong River is a very long body of water that flows through Laos, China, Myanmar, Thailand, Cambodia, and Vietnam. Eventually, the river lets out in the Mekong Delta in the South China Sea of the Pacific Ocean.

This river supports millions of humans in rural areas as well as cities throughout its course. The Mekong River is also renowned for its diverse wildlife.

5. Amazon River

The Amazon River is locked in perpetual combat with the Nile River for the title of the longest river in the world. Depending on the measurements that one accepts, this river might just be the longest of them all. One thing is for certain: this river is long and supports some of the greatest biodiversity in the world.

4. Zambezi River

The Zambezi River runs through many countries in East Africa, providing water and hydroelectric power to people in the area. The river is critical to agriculture along its banks, but it does not flow through many major cities before reaching its mouth in the Indian Ocean.

3. Danube River

The Danube River is known for being the second-longest river in all of Europe. However, more people live along the banks of this river than on the Volga River, the longest river in Europe. The Danube River flows through cities like Vienna and Budapest. The greatest depth of this river is 584ft, a significant among deeper than the Zambezi River.

2. Yangtze River

The Yangtze River is the longest in all of Asia and is third to the Nile and Amazon rivers in terms of length. This massive river flows throughout China from west to east, eventually ending in the East China Sea. This river is important for transportation, power, agriculture, and more throughout the country. It is one of the most influential rivers in Asia!

1. Congo River

The Congo River is the deepest in the world, measuring 720ft at one portion of its run. This river starts in the Democratic Republic of the Congo and flows through the country to its mouth in the Atlantic Ocean. The river is famous for being the only major river to pass over the equator twice throughout its run.

Identifying the Deepest Rivers in the World

The rivers we have listed here have been measured in the past with some certainty. Still, we recognize that deeper rivers may exist as they can run hundreds or thousands of miles long. Also, river depths can change over time.

In other words, the list of the deepest rivers in the world is changeable and could be altered in the future! We’ll keep a lookout for new information about river depths around the world!
