Ярмук
In 1964, Israel began operating a pumping station that diverts water from the Sea of Galilee to the National Water Carrier. Also in 1964, Jordan constructed a channel that diverted water from the Yarmouk River, a main tributary of the Jordan River, to the East Ghor Canal. Syria has also built reservoirs that catch the Yarmouk's waters. Environmentalists blame Israel, Jordan and Syria for extensive damage to the Jordan River ecosystem.
