MUHAMMAD AYUB KHAN WORDS & EFFORTS FOR THE TREATY “But before I write of the negotiations with Eugene Black, I should like to describe the confrontation I had with our own technical experts and administrators. I sensed that they did not fully realize the gravity of the situation and were asking for the moon when we were in a position of weakness all along the line. They were also trying to dictate policy and were taking up extreme positions. Some thirty or forty of them were assembled in a Government House, Lahore, where I addressed them. I said:
MUHAMMAD AYUB KHAN WORDS & EFFORTS FOR THE TREATY Gentlemen, this problem is of far-reaching consequences to us. Let me tell you that every factor is against Pakistan. I am not saying that we should surrender our rights but, at the same time, I will say this: that if we can get a solution which we can live with, we shall be very foolish not to accept it. Now when I say that, I am in fact saying it to myself because I shall have to take the responsibility for the solution. ” Ref: Friends, Not Masters by Muhammad Ayub Khan, President of Pakistan
MUHAMMAD AYUB KHAN WORDS & EFFORTS FOR THE TREATY “The responsibility does not lie on any of you, so let me tell you very plainly that the policy is going to be mine. I shall consult you whenever I am in doubt regarding technical details, but if anyone of you interferes with my policy, I shall deal with him myself. This problem, if not tackled properly, may well mean the end of the country. I mean every word of it. So, don’t let anyone make any mistake about it. ” Ref: Friends, Not Masters by Muhammad Ayub Khan, President of Pakistan
MUHAMMAD AYUB KHAN WORDS & EFFORTS FOR THE TREATY “What we were being called upon to this is to barter away natural flowing waters into our canals, for storage water, and the history of storage is that it begins to silt the moment it is completed. Besides, we are going to put back by about ten years or so by building these storages and link-canals. All this efforts could have been put to more constructive effort. So, we are making great sacrifices. ” Ref: Friends, Not Masters by Muhammad Ayub Khan, President of Pakistan
MUHAMMAD AYUB KHAN WORDS & EFFORTS FOR THE TREATY “As I explained to my people at the time of signing the Treaty, the solution that we had finally arrived at was not the ideal one but it was the best we could get under the circumstances. ” Ref: Friends, Not Masters by Muhammad Ayub Khan, President of Pakistan
MUHAMMAD AYUB KHAN WORDS & EFFORTS FOR THE TREATY “After years of negotiations of the utmost complexity, heart-breaking delays and frequent stalemates, we had, I felt, been able to obtain a solution which was adequate. So, whereas there was no cause for rejoicing at the signing of the Treaty, there was certainly cause for satisfaction that a possibly very ugly situation had been averted. ” Ref: Friends, Not Masters by Muhammad Ayub Khan, President of Pakistan
MUHAMMAD AYUB KHAN WORDS & EFFORTS FOR THE TREATY “With the signing of the Treaty, a chapter of long and uneasy negotiations and suspense in our national affairs came to an end. We entered a period of sustained hard work to provide the huge storages and immensely long link-canals for the alternative sources of water. By 1970 we hope to have completed these works, and when that is done we shall be independent of India in the matter of water supply. ” Ref: Friends, Not Masters by Muhammad Ayub Khan, President of Pakistan

If a work would cause interference with the waters of any of the Rivers but would not, in the opinion of the Party planning it, affect the other Party materially, nevertheless the Party planning the work shall, on request, supply the other Party with such data regarding the nature, magnitude and effect, if any, of the work as may be available.
Resolution of disputes Name of Project Salal Dam Period of Dispute Resolution 1970 -1978 (8 Years) Baglihar HEP 1992 – 2007 (15 Years) Kishenganga HEP 1994 – 2013 (19 Years)
PAKISTAN’S CONCERNS AGAINST INDIA’S ATTITUDE • • Designs in violation of the Treaty Criteria i. Excessive Freeboard ii. Deep Orifice Spillway iii. Excessive Pondage India starts construction without informing Pakistan (Chutak HEP, Wullar/Tulbul) • India does not provide data of the projects as per requirements of Article VII(2) • India plans/constructs projects that are in clear violation of Treaty (Tulbul Navigation Project/Wullar Barrage) • India stalls on the discussions on the projects with intent to bring these near completion before Pakistan opts for NE/COA • India is unmindful in implementing the operational provisions of the Treaty (initial filling of Baglihar)
WAYFORWARD FOR SMOOTH IMPLEMENTATION OF IWT A need to bilaterally agree upon: (i) to improve the data quality by following the internationally accepted practices; (ii) to disseminate the real-time quality-assured gauge and discharge data by employing the modern equipment like telemetry; (iii) to improve the management of upper watersheds;
WAYFORWARD FOR SMOOTH IMPLEMENTATION OF IWT (iv) to ensure the sharing of future projects’ plans and designs at inception stage; (v) to formulate the procedures for determining various parameters of the new projects consistent with sound and economical design and satisfactory construction and operation of the works while remaining within the statutory regulation of the IWT.
INTERPROVINCIAL ATER APPORTIONMENT ACCORD (WAA
WATER APPORTIONMENT ACCORD - 1991 • Water Apportionment Accord was mutually agreed by the four provinces and signed in 1991 • This accord defines the water sharing formula for distribution of Indus Basin flows among the provinces • 1977 -82 historic canal diversions (102 MAF) were made basis for allocation of the waters of the Western Rivers (Indus, Jhelum and Chenab) to the provinces; contributions from Eastern Rivers are negligible • The Accord also defines the water allocations corresponding to various water availability scenarios (dry, average and wet conditions)
INDUS RIVER SYSTEM AUTHORITY • Indus River System Authority (IRSA) was established in 1992 by the Government of Pakistan for implementation of the Accord • IRSA is responsible for determining the seasonal water allocations and also for regulation of the reservoirs, link canals and headworks in the sense that the distribution is as per provincial shares and shortage to the system is evenly distributed • Indus River System Authority (IRSA) comprises five (05) members; four from the provincial irrigation departments and one as a federal member. • Chairman of the Authority is appointed for one year, on rotational basis.
OPERATION OF IRSA • Knowledge base i. e. observed gauge and discharge data, is provided by provincial irrigation departments • Seasonal water availability scenarios and system operation are planned by IRSA in consultation with provincial irrigation departments and WAPDA; due considerations are given to storage available in the reservoirs • Seasonal water allocation plans are made by IRSA before start of the winter and summer crop seasons i. e. Rabi and Kharif.
OPERATION OF IRSA • Anticipated shortages in the system are also communicated in seasonal plans so that provinces could mange their water demands within their allocation. • Day to day operation is monitored by IRSA through collection of observed flows at rim stations and diversion to various canal commands through barrages. • Anticipated seasonal allocations are revisited in the middle of season to update/revise the allocations.
