Irkutsk reservoir is located on the Angara River. It is located in the Irkutsk region. As mentioned earlier, its area is about 155 km 2. In length, it reaches 65 km, and in width - from 4 km or more. The total useful volume of the reservoir is 46.5 billion m 3.

It was created together with the Irkutsk hydroelectric station built there in 1958 to regulate the flow of water. Initially, the filling of the store lasted for 7 years. Even despite the fact that the Irkutsk Hydroelectric Power Station is a low-pressure channel bed, it was necessary to flood or flood about 139 thousand hectares of land in order to provide the necessary volumes of water. After filling the Irkutsk reservoir in Lake Baikal, the average water level rose by 1 m.

Flora and ichthyofauna

Small rivers and streams flow into the reservoir. The exception is two large rivers - these are Alanka and Kurma. Due to the flatter right bank, the tributaries here are more powerful than in other areas.

In the lower parts of the valleys of the tributaries of the Angara River, as well as in the place of formation of the storage itself, bays formed. In the Irkutsk reservoir, the largest of them is Kurminsky. Its area is just over 20 km 2, and its length is 11 km. In it you can meet various species of fish, the main representatives of the ichthyofauna of the bay are taimen, lenok and grayling. It should be noted that commercial fishing is prohibited throughout the Kurminsky Gulf and the Irkutsk Reservoir. Compliance with the rules of fishing is monitored by a special inspection, preventing the illegal extraction of underwater inhabitants by poachers.

The coast of the reservoir mainly consists of pine forests. In those places where the forest was cut down, birch trees were planted. Here you can find absolutely wild areas where the presence of man was minimal, and nature remained in a virgin state.
