The Jordan River originates from three main springs: Banyas in the Occupied Golan Heights, Dan in Israel, and Hasbani in Lebanon. The water of the Jordan River flows southward through Lake Hula towards Lake Tiberias (the Sea of Galilee). The lower part of the river flows downstream of Lake Tiberias and joins the Yarmouk and Zarqa rivers, which spring from Syria and Jordan respectively. The river continues to flow southwards until it spills into the Dead Sea at approximately 400 metres below sea level. In truth, by the time the Jordan River reaches the Dead Sea, the river is dry and as a result, the Dead Sea is contracting. The entire length of the Jordan River is 360 kilometres with a surface catchment area of about 18,300 square kilometres. Forty percent of the water used in Israel comes from the Jordan River.
