The article presents new modern ways to increase the receiving capacity and preserve the water content of lake basins on the territory of the Volga-Akhtuba floodplain natural Park. The main factor that caused the need for rehabilitation of the rivers and lakes of the Volga-Akhtuba floodplain is the change in the hydrological and ecological situation that arose as a result of the change in the hydrological regime by regulating the flow of the Volga River after the construction of the Volga hydroelectric power station. The rehabilitation of water objects is aimed at preserving and restoring the water objects to a state that provides environmentally favorable living conditions for the population; ensuring the protection of the population from low water (water scarcity), for the restoration and environmental rehabilitation of the water objects and the adjacent territory.
