The Western Dvina River, also known as the Daugava, is a major river in Eastern Europe. It flows through Belarus, Latvia, and Russia, spanning approximately 1,020 kilometers. The river is an important waterway for transportation and has historically served as a trade route. The Western Dvina originates in the Valdai Hills of Russia and eventually empties into the Gulf of Riga in the Baltic Sea. Its basin supports diverse ecosystems and is home to various fish species, making it significant for both ecology and local fishing industries.
