DUNAJEC RIVER

river in southern Poland, rising in the Tatra Mountains near the Slovak border and flowing about 156 miles (251 km) northeast into the Vistula River. It is dammed for hydropower at Roznw, Czchw, and Czorsztyn. It was the scene of heavy fighting in World War I when the Germans broke through the Russian trenches. In March 1975 Czechoslovakia and Poland modified their border along the Dunajec to permit Poland to construct a dam for irrigation in the Czorsztyn region, southeast of Krakw.
