The Sea of Galilee, also called Lake Tiberias, Genezareth Lake or Kinneret, is a freshwater lake in Israel. It is the lowest freshwater lake on Earth and the second-lowest lake in the world, with its elevation fluctuating between 215 and 209 metres below sea level. It is approximately 53 km (33 mi) in circumference, about 21 km (13 mi) long, and 13 km (8 mi) wide. Its area is 166.7 km2 (64.4 sq mi) at its fullest, and its maximum depth is approximately 43 metres (141 ft). The lake is fed partly by underground springs, but its main source is the Jordan River, which flows through it from north to south with the outflow controlled by the Degania Dam.
