Next decade when the Sea of Galilee is still low b. Transition period when the Sea of Galilee is high but flows downstream are negligible c. Return of overflows to the LJR, albeit not in historical magnitude Overall improvement in flows and quality, especially in period C: •Still be less than 10% of historical flows •Environmental goals are not met •Salinity wise, the river will be split at the confluence with Harod •Effect of overspills from the Sea of Galilee will be limited to a few months Reintroduction Scenario Current Accounts Zero Scenario Reintroduction Scenario Reintroduction Scenario Measures Measure 1 2 3 MCM Cease pumping from lower Yarmouk to the SoG, if the later is higher than the bottom red line The brine of the SWC will be transferred to the -8 Dead Sea Salinity ton/Yr NIS (Undiscounted) 3 Capital Fixed Per m 2,300 -0.09 47,000 130m -necessitates a 83 km long, 2 -less water to the AMWA fish 1.2m 0.07 - Homa spring will be partiall - necessitates a 15 km long, 3 10-15 6 7 Diminish fresh agriculture by 30% by 2020 8 Maintain present consumption level in the UJR 27 ++ - - 1.6 9 Discharge some of the effluents of the Kishon 2-3 to Harod River to reduce salinity Desalination of 1.5 MCM/Yr of the SWC water, on top of the current plan + - - - - 1.5 5 10 40m -saving in pumping energy -Does not contribute water w 3.9m Transferring effluents from Kishon to AMWA and Harod Further and faster decreasing pumping to the 1 NWC Exchanging 50% of the fishponds with field 2 crops and alfalfa Diminish saline agriculture by 30% by 2020 4 - Remarks 3 30 ++ 1.55 -price per m calculated by a pumping costs to the NWC [3 10 36,000 0.2 - price per m represents the cubic meter used in the pond 10 + 0.7 9-12 + 1.6 - price per m represents the cubic meter of saline water ] 3 - price per m represents the cubic meter of fresh water ]1 Keeping the current original quotas -Less water available for AM reduced profits in case of sho 3,000 7 m 3 3 - 1.5 MCM/Yr is the maximum flow of the SWC springs fluct - variable costs include pump Reintroduction Scenario Water level in the Kinneret -208 -209 Meters MSL -210 -211 -212 -213 -214 -215 Reintroduction Scenario Zero Scenario Top Red Line Bottom Red Line Black Line 1.3m Reintroduction Period C averages Reintroduction Scenario Net costs & lost revenues 370 million for dealing with the SWC and its brine. 1,300 million to decrease flow in the NWC. 100 million to transfer effluents from the Kishon Water Works. 730 million in lost revenues for the farmers in the LJR basin. 970 million in lost revenues for the farmers in the UJR basin. Possibility to pump 40 MCM/Yr from the river for saline irrigation at Emeq Hamaayanot – revenues of 600 million NIS Downstream Bezeq Stream – water can be used for saline irrigation up until Adam Bridge Reintroduction Scenario Effectiveness of measures Parameters Env.

The situation will somewhat improve over the next decades but not enough. Salinity-wise the Jordan River will be split at Harod stream. Releasing 125 MCM/Yr from the Sea of Galilee will be sustainable within 10-15 years Partial restoration of the Jordan River can be achieved at an expense/lost revenues of 3.4 billion NIS over the next 30 years Thank you for listening Gilad Safier M.Sc in Hydroinformatics 054-9444118 [email protected]
