The mouth of the Volga River is located approximately 92 feet (28 metres) below sea level.1

This elevation corresponds to the surface level of the Caspian Sea, into which the river discharges. Because the Caspian Sea is an endorheic basin, its water level is subject to long-term fluctuations caused by climatic changes, which affect the balance between river inflow, precipitation, and evaporation.12
