The article describes the geoecological state of the steppe ilmenno - tuberous plain of the Caspian lowland. The choice of this topic is due to the fact that as a result of the analysis of long - term studies of aquatic ecosystems - territories located in near - coastal areas, catastrophic changes in most of the many landscape components under the influence of anthropogenic load are noted. Of particular concern is the hydrological status of all types of watercourses, and especially steppe ilmeni. Significant damage to the region’s water supply is associated with regulation of runoff of the river. Volga, which led to a violation of the hydrological regime of the Lower Volga, especially in the estuarine areas. To date, the authors have noted a sharp shortage of drinking water in ilmeni, a significant reduction in the area of agricultural land, which leads to the intensification of the processes of drying and salinization of most of them and mass extinction.
