The Wazzani's and the Haqzbieh's combined discharge averages 138 million m³ per year. About 20% of the Hasbani flow emerges from the Wazzani Spring at Ghajar, close to the Lebanese Israeli border, about 3 kilometres west of the base of Mount Hermon. The contribution of the spring is very important, because it is the only continuous year-round flow in the river in either Lebanon or Israel.
