The Volga Hydroelectric Station, located on the Volga River, directly impacts the Caspian Sea. The Volga River, Europe’s longest, flows into the Caspian Sea and contributes about 80% of its freshwater inflow. The construction of the Volga Hydroelectric Station and other dams along the river has altered its natural flow, reducing the volume of water reaching the Caspian Sea. This reduction has contributed to the sea’s declining water levels. https://earthobservatory.nasa.gov/images/150452/the-caspian-...
