The Daugava is a major river in Eastern Europe, flowing through Latvia, Belarus, and Russia. It stretches approximately 1,020 kilometers (634 miles) and is known for its scenic beauty and historical significance. The river originates in the Valdai Hills of Russia and eventually empties into the Gulf of Riga in the Baltic Sea. The Daugava serves as an important waterway for transportation and trade, particularly in Latvia. It is also a vital source of hydroelectric power, with several dams built along its course. The river supports diverse ecosystems and is popular for recreational activities such as fishing and boating.
