Yenisei

geography Maturity 7-9 Next article →

The Yenisey is a massive and vital river system in central Siberia. It ranks as the fifth-longest river system in the entire world. It is also the largest river system that drains into the Arctic Ocean. This massive flow of water drains a huge portion of central Siberia. The river acts as a natural boundary for the land. It separates the Western Siberian Plain in the west from the Central Siberian Plateau in the east.

The journey of the Yenisey begins high up in Mungaragiyn-gol in Mongolia. From its source, the river follows a northerly course through the landscape. It flows through Lake Baikal, which is the oldest and deepest lake on Earth. The river eventually reaches the Yenisey Gulf in the Kara Sea. Its delta is formed between the Gyda Peninsula and the Taymyr Peninsula.

The river is very deep in many places. Its maximum depth reaches 60 meters, while its average depth is 16 meters.

Many different rivers, known as tributaries, join the Yenisey along its path. These tributaries add more water to the main system. The largest tributaries include the Little Yenisey and the Great Yenisey. Other major rivers that flow into it are the Angara and the Podkamennaya Tunguska. The river flows through several Russian federal subjects. These include Tuva, Khakassia, and the Krasnoyarsk Krai. The river basin covers a vast area of 2,580,000 square kilometers.

History shows that people have known about this river for many centuries. The first written mention of the river dates back to the 7th century. At that time, Chinese records called it "Kem." This name appeared in the Book of Zhou and the History of the Northern Dynasties. Different groups used various names like "Jian River" or "Qian River." In the 1700s, Chinese maps still referred to it as the "Kem River."

The exact origin of these names remains a mystery to researchers.

By the 1600s, Russian explorers reached the lower parts of the river. They likely adopted the name "Yenisei" from Samoyed-speaking people. Around the same time, Dutch navigators were exploring the area. They used names like "Gilissi" or "Geniscea." These names are phonetically similar to the modern name. The Russian spelling has stayed mostly stable since the 17th century. Today, the name "Yenisei" is used globally to describe this great river.

The Yenisey basin supports a rich variety of life. There are 55 native fish species living in these waters. This includes the Siberian sturgeon and the grayling. The river valley is also home to many trees. Siberian pine and Siberian larch are very common in the area.

The river is also important for large animals. The Taimyr reindeer herd is the largest in the world. This herd has reached over one million individuals. They migrate to the river's winter grazing ranges.

Humans have used the Yenisey for transport and power for a long time. Steamers first arrived in 1864 to move supplies through the icy Kara Sea. These ships helped connect land-locked parts of Siberia to the world. Later, boats were used to bring rails and engines for the Trans-Siberian Railway. Today, the Krasnoyarsk Dam is a major feature on the river.

The dam includes a canal inclined plane. This allows boats to move past the dam safely.

This engineering helps keep the river a useful route for travel.
