Jordan River Water Disputes and the Road to the Six-Day War
Water has long been a strategic asset in the Middle East, often serving as both a lifeline for development and a catalyst for conflict. In the years leading up to the 1967 Six-Day War, the Jordan River basin became a primary flashpoint between Israel and its Arab neighbors. What began as a struggle over irrigation and resource management evolved into a series of military confrontations that significantly destabilized the region.
The Struggle for Water Infrastructure
In July 1953, Israel began constructing the intake for its National Water Carrier, a massive project designed to transport water from the north to the arid south. The initial construction site was located at the Daughters of Jacob Bridge (Gesher B'not Ya'akov), situated in a demilitarized zone north of the Sea of Galilee. This move prompted an immediate response from Syria, which deployed armed forces and opened fire on the engineering sites.
Despite a 1954 United Nations resolution supporting the resumption of work, the USSR vetoed the measure. Consequently, Israel relocated the intake to its current position at Eshed Kinrot on the north-western shore of the Sea of Galilee.

The Johnston Plan and Unilateral Development
In 1955, an attempt was made to establish a multilateral approach to water management known as the Johnston Plan (or Unified Plan). Although the plan was never formally ratified, both Israel and Jordan agreed to operate within the water allocations it prescribed. This period saw the development of two major projects: Israel's National Water Carrier and Jordan's East Ghor Main Canal.
Jordan began designing the East Ghor canal in 1957 as part of the more ambitious Greater Yarmouk project. This comprehensive scheme included the construction of dams on the Yarmuk River (Mukheiba and Maqarin) for storage and electricity, as well as various pumping stations and flood protection facilities. Construction began in 1959, with the first sections becoming operational by 1961 and further sections by June 1966.
The Headwater Diversion Plan
By 1964, Israel began withdrawing 320 million cubic meters (MCM) of water per year via the National Water Carrier. While this volume was within the limits of the Johnston Plan, it sparked intense political alarm among Arab states. At a January 1964 summit in Cairo, the Arab League viewed the diversion of water as a threat to Arab existence and a tool to enhance Israel's capacity to absorb immigrants at the expense of Palestinian refugees.
To thwart the Israeli project, the Arab states launched the Headwater Diversion Plan in 1965. Rather than a direct military attack, they sought to divert the sources of the Jordan River—specifically the Hasbani and Banias rivers—across the Golan plateau and into the Yarmuk River, where the water would be stored behind the Mukhaiba dam.

Escalation to Military Conflict
Israel viewed the diversion project as an infringement of its sovereign rights. Estimates suggested that the plan would have deprived Israel of 35% of its intended withdrawal from the upper Jordan, representing one-ninth of the country's total annual water budget. In response, the Israeli army launched a series of strikes against the diversion works in Syria during March, May, and August of 1965.
These strikes triggered a "prolonged chain reaction of border violence." Between 1964 and 1967, incidents escalated from artillery exchanges and tank battles to full-scale air strikes deep inside Syrian territory in April 1967. This cycle of hostility over water rights is widely regarded as a major contributing factor to the outbreak of the Six-Day War in June 1967.
Key Facts
- National Water Carrier: Israel's project to move water from the Sea of Galilee to the south, withdrawing 320 MCM/yr by 1964.
- Headwater Diversion Plan: An Arab League effort starting in 1965 to divert the Hasbani and Banias rivers to prevent them from reaching Israel.
- Water Impact: The diversion plan would have reduced Israel's upper Jordan water withdrawal by 35% (1/9th of its annual budget).
- Johnston Plan: A 1955 failed ratification attempt at multilateral water management that nonetheless provided a framework for water quotas.
- East Ghor Main Canal: Jordan's primary irrigation project, part of the larger Greater Yarmouk project.
| Project Name | Primary Actor | Main Objective | Key Outcome/Status |
|---|---|---|---|
| National Water Carrier | Israel | Transport water from north to south | Operational; 320 MCM/yr withdrawal |
| Headwater Diversion Plan | Arab States | Divert Hasbani and Banias rivers | Thwarted by Israeli military strikes |
| East Ghor Main Canal | Jordan | Irrigation via the Yarmuk/Jordan basin | Completed in stages (1961-1966) |
| Johnston Plan | International/US | Multilateral water allocation | Not ratified, but used as a quota guide |
Frequently Asked Questions
What was the National Water Carrier?
The National Water Carrier was an Israeli infrastructure project designed to pump water from the Sea of Galilee in the north to the southern regions of the country for irrigation and domestic use.
Why did the Arab states attempt to divert the Jordan headwaters?
The Arab states aimed to prevent the Jordan headwaters from reaching Israel to thwart the National Water Carrier and limit Israel's ability to support a growing population and absorb immigrants.
How did the water dispute contribute to the Six-Day War?
The dispute led to a cycle of border violence, including artillery fire and air strikes between Israel and Syria from 1965 to 1967, which escalated into the full-scale war in June 1967.
What was the significance of the Johnston Plan?
Although it was not officially ratified, the Johnston Plan provided a set of water quotas that both Israel and Jordan initially agreed to follow, allowing for the development of their respective water projects.
Which rivers were targeted in the Headwater Diversion Plan?
The plan focused on diverting the Hasbani and Banias rivers across the Golan plateau and into the Yarmuk River.
