In the final reckoning, Pakistan got about 80 per cent of the Indus and India 20 per cent. India has limited rights on the western rivers and cannot undertake projects on those rivers without providing all the details to Pakistan and dealing with Pakistan’s objections. Why did India put itself in that position? The answer is that if Pakistan got the near-exclusive allocation of the three western rivers, India for its part got the eastern rivers. This was important from the point of view of the Indian negotiators because the water needs of Punjab and Rajasthan weighed heavily with them in seeking an adequate allocation of Indus water for India. Yet, Punjab had a serious grievance over the signing of the IWT [Indus Waters Treaty] by the union government. Citing provisions of the IWT which caused transfer of three river waters to Pakistan, Punjab had terminated all its water-sharing agreements with its neighbouring states in 2004.
The demand of Kutch (in Indian Gujarat), which used to fall into a catchment area of River Indus, decades back, was not taken into consideration despite many petitions, arguing about their historical claim on its water, sent by the prominent Kutchi leaders, in 1950s, to India’s Ministry of Irrigation and Power. Also people from the Indian side of Kashmir always show their ire against the IWT. On 3 April 2002, the Jammu & Kashmir Legislative Assembly, cutting across party affiliations, called for a review of the treaty. The state government has been contending that in spite of untapped hydroelectric potential, the state has been suffering from acute power deficiency due to restrictions put on the use of its rivers by the Indus Treaty. They claim that their interests were not taken into consideration and their views were not taken while signing the treaty. (6-7)
