See Genezareth
The Jordan River has an upper course from its sources to the Sea of Galilee, and a lower course south of the Sea of Galilee down to the Dead Sea. In traditional terminology, the upper course (or most of it) is commonly referred to as passing through the "Hula Valley", as opposed to "Upper Jordan Valley"; the Sea of Galilee through which the river passes is a separate entity; and the term Jordan Valley is reserved for the lower course, fed by the Yarmouk and Zarqa Rivers.
