The four rivers join to form the Jordan in northern Israel, near kibbutz Sede Nehemya. The Jordan drops quickly in a 75 kilometer run to Lake Hula, which is a little below sea level in the Galilee sea. Then it drops much more in about 25 kilometers to the Sea of Galilee. The last section has less gradient, and the river begins to twist before it enters the Dead Sea, which is about 400 meters below sea level and has no outlet. Two major tributaries enter this last section from the east: the Yarmouk River and Jabbok River.
