Flood begins in April - May. During the spring ice drift, congestion may form. The water level at this time can range from 5 m in the extended upper reaches of the river, up to 16 m in narrowed sections.
The Yenisei River ranks first among the rivers of Russia in terms of runoff. It is 624 km³.
The average water discharge is 19800 m3 / s (at the mouth), the maximum is at the river Igarka - 154,000 m3 / s.

The Yenisei River. Economic use and its protection
Uncontrolled fishing leads to a decrease in species diversity.
The Yenisei River played a huge role.
The economic use of its waters at nuclear power plants ledto radiation contamination of water in the river. So in the 1950s several nuclear reactors were put into operation at the mining chemical plant, which used water from this river. After cleaning the nuclear reactors, the water was discharged back into the river.
The use of the Yenisey River by man leads toThe fact that his water is littered with various garbage (both domestic and petroleum products). Therefore, it is necessary to take measures to protect the environment in order to preserve the flora and fauna of the river and the purity of its waters.
