Description of the underwater landscape of the biotope: The flow in the Seversky Donets in the main channel is quite fast and it is difficult to fix any vegetation on the sandy bottom. However, trunks of broken trees can form small islands, which bypass the main stream. As a result, an entire ecosystem forms around such oases. Plants cling to the ground. Under the driftwood there are bottom species of fish and crayfish, and among the leaves of plants many fish and schools of fry swim.
Description of the parameters of the habitat: The water is clear with a slight suspension, the temperature fluctuates throughout the year, in the summer the sandbank warms up to +27, pH 7.5
