  7. IRSA was established vide Act No. XXII of 1992 passed by the Parliament and approved by the President of Pakistan on, the 6th December 1992; One of the prime responsibilities of IRSA is the regulation and distribution of surface waters amongst the Provinces according to the allocation and policies spelt out in the Water Accord 1991; To Settle any question that may arise between two or more Provinces in respect of distribution of river and reservoir waters; Contd…

  8. Any question in respect of implementation of Water Accord shall be settled by the Authority by the votes of the majority of members and in case of an equality of votes the Chairman shall have a casting vote ; A Provincial Government or the Water and Power Development Authority may, if aggrieved by any decision of the Authority, make a reference to the Council of Common Interests (CCI).

  9. PROVISIONS OF WATER ACCORD 1991 PERTAINING TO DISTRIBUTION OF WATER

  10. Para 14 (b) The record of actual average system uses for the period 1977-82, would form the guide line for developing a future regulation pattern. These ten daily uses would be adjusted pro-rata to correspond to the indicated seasonal allocations of the different canal systems and would form the basis for sharing shortages and surpluses on all Pakistan basis.

  11. Para 14 (b)(MAF)

  12. Para 2

  13. Comparison of Para 2 vs Para 14 (b)(MAF)

  14. Para 4 Balance river supplies (including flood supplies and future storages) shall be distributed as below:Punjab 37 % Sindh 37 % KPK 14 % Balochistan 12 % Total 100 %

  15. Present Distribution Mechanism of IRSA(THREE TIER FORMULA SINCE 2003) Scenario I Water Availability < Actual Average System Uses 77-82 Distributed as per 14 (b) of the WAA 1991 Scenario II Water Availability > Actual Average System Uses 77-82 but < Para 2 of WAA 1991 Actual Average System Uses are protected Balance available as per Para 2 i.e. 10-daily approved by CCI Scenario III Water Availability > Para 2 of WAA 1991 Para 2 i.e. 10-daily approved by CCI are protected Balance as per Para 4 of the WAA 1991 Note: KPK & Balochistan are exempted from shortages 16

  16. Para 6 The need for storages, wherever feasible on the Indus and other rivers was admitted and recognised by the participants for planned future agricultural development. 17

  17. Western & Eastern Inflows & D/S Kotri Post Tarbela Average(1976.77 to 2009.10)(MAF)

  18. Provincial Canal Head Wdls(Post Independence to to-date) 19

  19. Reservoir Sedimentation (MAF) 20 * Excluding raising component. After raising additional 2.99 MAF would be available

  20. Historical vis-à-vis Present Peaks at Different Rivers/Barrages Since 1947 (Cs) 21

  21. Issues 22

  22. Presently, due to sedimentation heavy shortages are being faced by the provinces during Late Rabi (March) as well as Early Kharif (Apr – Jun) periods (Creating provincial disharmony); Reservoirs normally touch the dead level in Late February & March (Critical period for Wheat maturity); Lean flows / erratic flows are being experienced in Early Kharif (Disturbing the sowing of Cotton Crops); The present storage component does not cater for the requirements of Existing Irrigation Infrastructure; Storage, as envisaged under Para 6 of the Accord, should be constructed on war footing basis; No feasible site at Chenab; Mangla has already been raised; Only Indus waters can be stored at different locations Contd…

  23. Storages are required to reverse the 70 – 30 % ratio; Pakistan Hydel Generation Potential is 65,000 MW Storage for managing the floods; India total storage of 81 reservoirs is 151.77 BCM; (123 MAF) Indian Hydel Generation 37,000 MW (Potential 84044 MW)
