Zarqa River

The Zarqa River is the second largest tributary of the lower Jordan River, after the Yarmouk River. It is the third largest river in the region by annual discharge, and its watershed encompasses the most densely populated areas east of the Jordan River. It rises in springs near Amman, and flows through a deep and broad valley into the Jordan, at an elevation 1,090 metres lower.

At its spring lays 'Ain Ghazal, a major archaeological site that dates back to the Neolithic. Archaeological finds along the course of the river indicate the area was rich in flora and fauna in the past.
