1. Introduction

The Jordan River Basin straddles territories in Lebanon, Syria, Israel, Jordan and Palestine. The river acquires its name after three major tributaries join its course north of Lake Tiberias, and it flows southwards towards Lake Tiberias.  Its natural exit from the Lake was dammed with gates so that the Lake became a large reservoir.  The river picks up water from tributaries that discharge water into it from the east and from the west.  The largest tributary to the Jordan is the Yarmouk that drains territories in Syria and Jordan, and passes by Israeli territories before it discharges into the Jordan.  The second largest tributary is the Zarqa River that drains purely Jordanian territories, and has an average natural flow of 96 MCM per year.  The capital city of Amman, and several other cities including Zarqa, Ruseifeh, Jarash and others are located in the catchment of the Zarqa River.   The population in the catchment is about two million people, and the industrial activities in the country were started in it since the 1950's before full awareness of the environmental impacts such industries could impact on water resources.

The proposed development of the Jordan River basin called for the utilization of the upper tributaries before the river exits from Lake Tiberias, and for the utilization of the lower tributaries before they join the river.  In effect the course of the Lower Jordan south of Lake Tiberias would be denied fresh water supplies and would transform into a drain for agricultural drainage water.  The proposed development was based on the sharing of the waters of the basin by the riparian parties, and subsequent undertakings of water projects for the development of the basin.  The proposed plan fell through politically after it was endorsed on the technical level by the concerned parties.  It was then thought proper to have it implemented in a staged manner.

The Hashemite Kingdom of Jordan obtained financial assistance from the United States to develop the unregulated flow of the Yarmouk River and the side wadis on the East Bank of the Jordan.  The unregulated flow was sufficient to develop some 10,500 dunums of arable lands in the Jordan Valley.  The constraint was water availability in the dry season (April through October) rather than the wet  season.  Small dams were built on minor side wadis to make water available in the dry season.  By 1967 about 11,400 hectars between the Yarmouk and the Zarqa were brought under perennial irrigation.   Any expansion in the irrigated area would require impoundment of flood waters by dams.  The regulation of the Yarmouk was stalled by riparian issues that were exacerbated by political factors.  Israel was a third riparian in addition to Jordan and Syria, and a state of war prevailed between Israel and the Arab states.  Another complication was the Syrian plans to develop the Yarmouk basin unilaterally.

Jordan went through a period of turmoil in the wake of the 1967 war.  The internal situation was finally brought under control in 1971.  Economic development had to be restarted and a special development plan was made drawn up for the Jordan Valley.  Irrigated agriculture was the backbone for economic and social development.  

2.         The King Talal dam

Any expansion of irrigated agriculture in the Jordan Valley depended on making more irrigation water available.  This is a function of two factors:

a)       improvement of irrigation efficiency

b)       making available more water in the dry season through regulation of flows.

The irrigation efficiency can be enhanced by the improvement of conveyance and distribution efficiency on one hand, and the introduction of modern irrigation technology for on-farm irrigation.  Networks of pipes conveying water under pressure replaced surface canals network, and drip irrigation and micro-sprinkler methods were introduced to the farms. The increase of water availability was dependent on flood water storage on one hand and on the degree of Yarmouk water depletion upstream through increased Syrian abstraction on the other. A minor factor was the depletion of the base flow of the side wadis inside Jordan through upstream diversions. The factors influencing the water availability in the Jordan valley are therefore as follows:

a)       conversion of surface conveyance and distribution methods into pipe networks

b)       use of advanced on-farm irrigation methods

c)       storage of flood water for use in dry months

d)       depletion of Yarmouk flows by Syria

e)       depletion of flows of side wadis

The final outcome of expansion in irrigated agriculture depended on the final combination of the above five factors, of which the first three have positive impact on the water availability objective and the last two, the Yarmouk depletion by Syrian abstractions and the modest depletions in Jordan, had a negative impact.  The net result depended on the cumulative outcome at any time of the simultaneous impact imparted by each of the above factors.

The development plan called for the expansion of 8300 hectars in irrigated agriculture, and the introduction of new on farm irrigation methods on 1000 hectars in the existing areas of irrigation.  The streams that could be impounded were the Zarqa River and Wadi Kafrein.  A dam had already been built on the latter, but the Zarqa flow was not regulated. A dam was planned for the Zarqa, to be built at a capacity of 56 MCM and could be raised to 86 MCM if the situation warranted.

The King Talal dam was started in 1971, and was completed in 1977 with a storage capacity of 56 MCM of which only 6 MCM were earmarked to dead storage. The bed load proved to be higher than anticipated and an extensive program for the Zarqa catchment was adopted to stabilize the soil and control erosion.  Requirements for more water justified the raising of the KTD sooner than expected, and the complicated raising project was started in 1983 and was completed in 1988.

 3.        Expansion in Irrigated Agriculture

Water availability from the Yarmouk was adequate in the wet months (November through March) and would allow the expansion in irrigated agriculture if more water became available in the dry months. The King Talal dam on the Zarqa served that purpose.  Although its total storage allows an expansion of about 4000 hectars, the conjunctive use of its water with the Yarmouk wet months flow allows for more. At the outset, the dam allowed the irrigation of about 6000 hectars, but later after the raising and after further depletion in the Yarmouk summer flow, the dam water was made to reach some 17000 hectars.   Only 11000 of them were under cultivation, and the rest awaited more water.  In effect, the Syrian depletions strained the supply to the Jordan Valley existing agriculture, and prevented the cultivation of 6000 hectars when they were ready to be worked.

The first pronounced impact of the KTD was the expansion in irrigated area at the outset.  The areas of its command totaled 6000 hectars sufficient to settle about 6000 families whose heads of household would work in direct agricultural jobs and in supporting services.  Before the dam was built, there were 8 villages poorly equipped with the requirements of infrastructure needed for social development.  There was one high school for boys and none for girls.  There were 12 other primary schools for boys and for girls.  There was a central outpatient clinic for all these villages, and there was no electricity, domestic water or telecommunication services to speak of.  Farm to market roads were not paved and were frequently rendered unusable when it rained.

The construction of the dam itself provided job opportunities for Jordanians around its site.  Such towns as Burma, Jerash, Majdal, Gaza refugee camp, Um Rumman benefited from the construction activities in the form of direct employment, and in the form of providing logistics for workers.  It was the pioneering construction project when law and order were reestablished in the country.  Two more years elapsed before other projects in the country got underway.

The completion of the dam coincided with a draught winter year, 1978-1979.  The following year was a wet year and the reservoir was filled in a 36 hours storm.  A similar storm occurred the following week and the spill was equivalent to the reservoir volume.  All other storms were practically spilled to a total of about 100 MCM.  When the reservoir was filled, an ancient road alignment was submerged.  It was the road built in the Roman times and rehabilitated and paved in the 1950's that connected the north of Jordan with its south, the King's road.  The economic and social impact of that was minor because there was a replacement highway built to modern specifications.

The filling of the reservoir coincided with the completion of the irrigation networks in the Jordan Valley.  Putting the land under perennial irrigation enabled the Jordan valley Authority to apply the land redistribution provisions of the Jordan valley Development Law of 1977.  The farm land was redistributed and the social impact of that was profound.  Small land owners had their ownerships increased and landless farmers became land owners.  There was not enough land to distribute to all landless farmers, but the pattern of land ownership improved to the advantage of the poorer.  Irrigation water started to flow to the new lands year around and agricultural production boomed.  Land services became much easier with the improved access to the farms through all weather roads.  Agricultural inputs and the hauling of output became much easier compared to earlier times.  Exports improved because the production of fruits and vegetables was off- season at a time when there was little competition in the nearby markets.  Farm incomes improved drastically, and the economy of the Valley started to take a much better shape. 

4.         Social Infrastructure

The development plan for the Jordan Valley called for the construction of schools, health centers, government buildings, streets, roads, social development centers, and agricultural marketing centers with grading and packing facilities.  It also called for the provisions of public utilities of domestic water, electricity and telecommunication services.  That burden was carried by the Jordan valley Authority, a government organization.  The role of the private sectors was in farming, in housing and all the economic activities.

When the dam was completed, so were the badly needed social infrastructure components in the villages of the Jordan Valley.  Schools were built and furnished, health centers were built and equipped including a rural hospital in the area of command of the dam. A social development center was built and furnished.  Domestic water and electricity were provided to the villages.   The electricity grid was connected to the national grid in the Plateau.  Later an advanced telecommunications  network was completed and the Valley was connected to the rest of the world through direct dialing services.  The schools were staffed and they were adequate for girls and boys at all levels of education including vocational training centers.  A Farmers' Association was established to care for the supply of inputs and the marketing of the produce in competition with other traders.

Financing was made available by the government for agricultural credits and for housing loans.  The activities were intensified in both fields.  Drip irrigation was introduced to the Valley and it expanded with incentives of agricultural credit.  Housing construction by beneficiaries also boomed.  The land redistribution provisions of the law included the redistribution of lands within planned towns and villages, and landless residents had access to land to build their housed with credits made available by the government.

New villages sprang up.  They were properly planned and provided with the infrastructure.   People responded by building houses and commercial facilities.  Old villages were expanded.  The number of villages increased from 8 to 12, and later the water of the dam reached four more towns to make the dependent villages 16 in number, and the population today reached about 120,000 people between the town of Kreimeh and the town of South Shuna.

The results were amazing.   By 1987, the average per capita income in the Jordan Valley matched the national per capita income of $1650.  The illiteracy rate was diminishing fast and the school enrollments matched those of the national averages.  Education of women became possible under improved family income conditions and availability of government schools nearby.  The life expectancy at birth soared from a modes 46 years in the early fifties to 72 years in 1987 for males, and 73 years for females.  The role of women expanded to cover sectors other than agriculture.  Handicraft centers, home based businesses and other employments opened up for women.

When the Valley development effort started in 1973, only one engineer had graduated from college, three lawyers, and a limited number of university graduates and other professionals.  Today, the number of university graduates per capita has matched the national averages, and the number of professionals has increased so much that a substantial number of them are unemployed.

A survey conducted in 1987 showed a rate of population increase in the Valley of about 6.5% per annum.  This is double the natural growth rate.  The portions of the Valley that have witnessed higher population growth rates than others is the Middle Jordan Valley commanded by the KTD.  The dam and the Jordan Valley development scheme succeeded in curbing the traditional rural-urban migration pattern, arresting it and then reversing it.

 4.        The Role in Supply of Municipal Water

The unregulated flow of the Yarmouk provided enough winter flow to pump from the Jordan Valley to Amman.  The water thus pumped is used in municipal purposes and wastewater is produced.  The wastewater flow gets treated in a plant in the catchment of the dam, and the effluent is regulated by the dam. The blend gets to be used for power generation and for irrigation.

About 45 MCM of water is pumped to Amman from the Jordan Valley.  This amount will be doubled by the year 2002.  The wastewater generated, treated to the standards for unrestricted uses in agriculture, will be added to the stock of irrigation water.  The dam makes the supply to Amman possible because it would compensate for the irrigation fresh water that is pumped for use in municipal purposes.  The pumped water is thus used twice: once in municipal purposes and another in irrigation.  The non consumptive use in power generation is also a byproduct in the cycle.

The current supply is sufficient to meet the requirements of  about half a million people living in West Amman, and the doubling of the quantity will double the number of beneficiaries.  Again, the supply is not done directly from the dam, but the existence of the dam is crucial to the operation of the water cycle. 

5.         The Role in Sustaining Existing Agriculture

The diversion requirements in the dry months from the Yarmouk increased at a time when its flow was being reduced by the Syrian depletions upstream.  Compared to the flow of 6.5 cms in August of 1961 when the East Ghor canal was started, the flow last August diminished to 1.95 cms, less than one third of what it used to be.  The reductions were partly compensated for by the King Talal Dam reservoir and by summer water that Jordan recovered from Israel under the Peace Treaty of 1994.  The dam was raised and has been impounding a maximum of 78 MCM.  The carrier canals have been extended northward to enable the water to reach more lands planted with citrus to supply them with crucial summer water.  The surface canals have been converted to pressure pipe networks with decent savings on the losses of conveyance and distributions.  The summer supplies have been enhanced with the releases from Lake Tiberias since 1995 and were increased since May 1997.  However, the role of the KTD has been crucial in sustaining the existing agriculture north of the Zarqa River.  The other two factors of enhanced efficiency and increased supplies helped also.

Savings were also effected through the use of drip irrigation methods.  Along with the new irrigation technologies, the advanced farming technologies were introduced too.  Plastic houses became in vogue and agricultural yields increased substantially.   

6.         Marketing of the Produce

The markets were receptive to the produce and their absorption capacity was enhanced by the increasing oil revenues.   However, the political developments in the region affected the markets.  Syria and Lebanon got busy with the civil war in Lebanon and their markets shrank.  The ability of the two countries to service foreign trade with foreign currency diminished.  The depression in oil prices reduced the absorption capacity of the Gulf market, and competition by other producers exacerbated the export challenge.  Concurrently, Jordan maintained an open bridge policy for imports from the West Bank, and the market prices on the domestic market were depressed.  The benefits of the Jordan Valley off season production were receding.

Then came the big blow in the aftermath of the Iraqi invasion of Kuwait.  The markets of the Gulf were closed to Jordanian goods and services, and the agricultural incomes suffered substantially.  A wave of about 300 thousand Jordanians were evicted from the Gulf states and they took up residence in Amman and Zarqa in the catchment of the KTD. There was sudden increase in demand for municipal water and there was generation of more wastewater.  The slow improvements in the performance of the wastewater treatment plant did not help improve the quality of the effluent, and that, too, hampered marketing possibilities in the wake of improved relations with the Gulf states.

The depressed farm incomes triggered a chain of reactions in the market.  It affected the factories that supply agricultural inputs and farm irrigation systems.  It also depressed the imports and the agricultural activities of the market. Coupled with other economic difficulties, the situation contributed to a modest growth rates in the economy, and more indebtedness of farmers to the credit institutions.  The lending capacity of banks and credit institutions decreased, and the borrowing ability of farmers diminished, all leading to a difficult agricultural economy conditions. 

7.         Raising of King Talal Dam

Jordan realized the importance of utilizing its share of the Yarmouk flow.  By 1983, and encouraged by a booming market for the Jordan Valley produce, the Jordan valley Authority embarked on a plan to extend irrigated areas further.  About 6000 more hectars could be brought under irrigation if only more water could be secured in the dry months to sustain about 12% of the area that would be planted with perennial crops.  A project was adopted to extend the King Abdallah canal to draw more water from the Yarmouk, and to raise the King Talal dam to a new height of 106 meters and a storage capacity of 86 MCM (78 MCM live).  The dam raising was started in 1984 along with the canal extension and both were completed in 1988 at a total cost of $90 million.  By the time the project was completed, Syria had increased its usage of the Yarmouk waters and the operation of the Jordanian project was suspended.  The dam impounded more water that was put to beneficial uses in supplying the existing areas with badly needed water, especially those dependent on the Yarmouk for their summer irrigation.

The operation of the dam would be enhanced with the completion of the Karama dam in the Jordan Valley.  This new dam would help regulate Yarmouk floods especially that a proper diversion structure has just been completed on the Yarmouk at Adassiya.  The KTD would be operated in conjunction with the operation of the Karama dam in order that enough water would be made available to irrigate the new extension of 6000 ha. The ultimate benefits would be reached once the two dams are operated along with the latest canal extension. 

8.         Importance of the King Talal Dam

It can be safely said that the King Talal dam is the most important water structure in Jordan.  In view of the latest developments on the Yarmouk by Syria, the Jordan Valley would have suffered a drastic set back had it not been for the role of the KTD.  It can reach the farm land of a total area of 17000 ha if and when needed.  This is important to protect the perennial crops in these lands from being lost because of the lack of summer water.  The dam is supporting the livelihood of about 120000 people living in the Jordan Valley.  Its role and the role of the Jordan valley development was pivotal in curbing the rural-urban migration pattern, and in reversing it.
