In 1964, Syria attempted construction of a Headwater Diversion Plan that would have blocked the flow of water into the Sea of Galilee, sharply reducing the water flow into the lake. This project and Israel's attempt to block these efforts in 1965 were factors which played into regional tensions culminating in the 1967 Six-Day War. During the war, Israel captured the Golan Heights, which contain some of the sources of water for the Sea of Galilee.
