1. Origin of the Mekong River

Originating from the perpetual snowcaps of the towering Tibetan Plateau, the Mekong River flows southward, crossing the rugged gorges of China (where it is known as Lancang Jiang), forming natural borders between Myanmar, Laos, and Thailand, continuing through Cambodia's rich Tonle Sap basin before branching into Vietnam.

Over 4,800 km in length creates one of the most biodiverse river basins on the planet, second only to South America's Amazon River basin. It is the common home to thousands of endemic freshwater fish species and rare submerged vegetation.

2. The Legendary Cuu Long River in Vietnam

When entering Vietnamese territory in An Giang province, the river splits into two major branches: the Tien River and the Hau River. The magic lies in how the river continues to separate and weave through a dense network of canals before emptying into the East Sea through nine great estuaries, which is why ancient folklore reverently named it the Cuu Long River (Nine Dragons):

Although today, natural alluvial deposition and irrigation dams have caused the Ba Lai and Bassac estuaries to disappear, the spirit of revering the sacred Cuu Long River remains an immortal symbol of the Western region of Vietnam.

3. The Great Ecological and Economic Role in Southwest Vietnam

The Mekong Delta is fully embraced by the rich alluvium of the Mekong River, deposited over thousands of years. The red alluvial water helps rice fields bear golden grains, providing a sweet nutritional source to nourish meaty shrimp and the famous rich and fatty Nam Can mud crabs. The Mekong River creates the country's largest rice bowl and an orchard bursting with fruit all year round.

In Ca Mau, the current continues to weave through shady small canals, mixing with the salty sea to create a unique ecosystem of mangroves and nipa palms. The floating season from September to November each year is when the gift of alluvium floods the fields, and linh fish head downstream from the upper reaches, bringing a bountiful harvest for fishermen.

Frequently Asked Questions

How many estuaries does the Mekong River currently use to flow into the East Sea?

Historically, the river flowed out through nine estuaries. However, only 7 active estuaries remain today, as the Ba Lai estuary has been completely dammed and the Ba Thac estuary has been filled with silt and stopped flowing since the last century.

Which season is the Mekong River most abundant?

That is the Western floating season, lasting from about September to the end of November every year. The water carries a rich amount of red alluvium flooding the fields, along with special linh fish and fresh water lilies.
