Key Points
- The Mekong River is known as the 'River of Nine Dragons' in Vietnam.
- It flows through six countries, starting in China and ending in the South China Sea.
- The river's delta advances ~80 meters/year, creating new fertile land.
Rivers are vital to our planet. Millions of rivers and streams run through hundreds of large river basins around the world. These waterways provide life, food, and water to billions of people.
In nature, records are everywhere. The Nile is the longest river on Earth. The Amazon is the largest river by water volume and is also seen as the widest. Rivers are very important, and different cultures have unique names for them.
But do you know which river is called the "River of Nine Dragons"? This famous waterway flows through six different countries in Asia.
It is known for its large delta. The water splits into many branches before reaching the sea. In this article, we will look at the history, culture, and secrets of this legendary waterway.

The Mekong River is called the "River of Nine Dragons". The Vietnamese named it this because it splits into several branches when it reaches the sea. The river starts high in the Tibetan Plateau in China.
It travels a long path of over 4,350 kilometres. It flows through six countries: China, Myanmar, Laos, Thailand, Cambodia, and Vietnam. Finally, the river empties into the South China Sea through a massive delta.
This waterway is the longest in Southeast Asia and is crucial for the survival of millions. It supplies water for farming, provides a habitat for thousands of species, and acts as a key transportation route for the entire region.
5 Lesser-Known Facts About the Mekong River
- The Mekong is home to the world's largest freshwater fish, including the giant stingray, which can weigh over 600 pounds.
- It ranks second only to the Amazon River in terms of global freshwater biodiversity per unit area.
- The Tonle Sap River in Cambodia is one of the only rivers in the world that reverses its flow direction twice a year.
- Scientists discover an average of two new species in the Mekong region every single week.
- The river carries approximately 160 million tonnes of nutrient-rich sediment annually to help fertilise the delta.

Why Mekong River is known as the 'River of Nine Dragons'?
In Vietnam, the Mekong River is called Sông Cửu Long, which means the "River of Nine Dragons." This name is very special to the local people and describes how the river looks and works. Here are the few reasons why it is called the River of Nine Dragons:
- Many Waterways: As the river reaches Southern Vietnam, it splits into many smaller branches and canals. On a map, these winding paths look like the long, powerful bodies of mythical dragons.
- The Nine Mouths: Historically, the river flowed into the sea through nine different openings. Each opening was seen as a "mouth" of a dragon.
- Ancient Legends: Local stories tell of nine dragons that came down from the sky to protect the land. People believe these dragons created the river branches to bring good luck and wealth to the region.
- A Source of Life: The river acts like a "Mother" to the land. It brings rich soil that helps farmers grow huge amounts of rice. Because it provides so much food and water, the river is treated with great respect, like a powerful legend.
Why Does The Mekong River Flow In The Backward Direction?
Most rivers follow a simple rule. They flow downhill toward the ocean. However, the Mekong River demonstrates a natural miracle with the Tonle Sap River in Cambodia.
During the dry season, the Tonle Sap flows into the Mekong. But when the monsoon rains arrive, the Mekong's water level rises so high and so fast that it pushes the water back upstream.
This "river reversal" causes the water to flow backwards into Tonle Sap Lake, which can expand to five times its normal size. This unique event works like a giant pulse, bringing nutrient-rich mud and millions of fish into the lake.
It is one of the few places on Earth where a river changes its direction twice a year, creating one of the most productive fishing grounds in the world.
How Does The Mekong River Build New Land Every Year?

The Mekong is often called a "geological architect" because it constantly creates new land. As the river flows from the mountains to the sea, it carries millions of tonnes of sediment. This sediment includes tiny pieces of rock, minerals, and organic soil.
When the river flows into the flat plains of the delta in Vietnam, the water slows down and begins to drop its heavy load of soil.
This process is so powerful that the coastline of the Mekong Delta can advance by about 80 meters each year. The river is creating new land. It is transforming the South China Sea into fertile green fields.
This new soil is rich in nutrients. That's why people call the delta the "Rice Bowl" of Asia. It feeds millions with crops grown on land that didn't exist a hundred years ago.
