East of the central highlands lies the Jordan Rift Valley, which is a small part of the 6,500-kilometer-long Syrian-East African Rift. In Israel the Rift Valley is dominated by the Jordan River, Lake Tiberias (known also as the Sea of Galilee and to Israelis as Lake Kinneret), and the Dead Sea. The Jordan, Israel's largest river (322 kilometers long), originates in the Dan, Baniyas, and Hasbani rivers near Mount Hermon in the Anti-Lebanon Mountains and flows south through the drained Hula Basin into the freshwater Lake Tiberias. Lake Tiberias is 165 square kilometers in size and, depending on the season and rainfall, is at about 213 meters below sea level. With a capacity estimated at 3 billion cubic meters, it serves as the principal reservoir of the National Water Carrier (also known as the Kinneret-Negev Conduit). The Jordan River continues its course from the southern end of Lake Tiberias (forming the boundary between the West Bank and Jordan) to its terminus in the highly saline Dead Sea. The Dead Sea is 1,020 square kilometers in size and, at 399 meters below sea level, is the lowest point in the world. South of the Dead Sea, the Rift Valley continues in the Nahal HaArava (Wadi al Arabah in Arabic), which has no permanent water flow, for 170 kilometers to the Gulf of Aqaba.
