Water reservoir-wintering pond is made deep of made ground and is built in the coastal shallow area of the lake. The wintering pond has an aerator-flow-generator, water intake and spillway channels having removable watertight partitions. The wintering pond is equipped with a rock dam. The rock dam connects the wintering pond with the water area free of water vegetation or crosses the entire lake. Along with the dam on its both sides and on the end the deep underwater channels are located. The water intake and spillway channels are connected to the underwater channels and serve as their continuation.
