Replacing storage lost by sedimentation in existing reservoirs at Mangala, Chashma and Tarbala (estimated about 3 MAF by the year 2000)
Providing additional storage to meet existing water shortages during early Kharif sowing period of April-June Regulation and control of high flood peaks in the Indus to enable provision of perennial tubewell irrigation to the riverain area in Sindh. As part of controversy on Kalabagh Dam, a number of apprehensions/doubts have been expressed both by upper (NWFP) and lower (Sindh) riparian provinces. Most of these are based either on lack of information or hear say. In addition, there have been reservations in the mind of some quarters without any apparent rhyme or reason. PROJECT BENEFITS
Kalabagh would store surplus water in the flood season and make it available for controlled utilization during the low flow season. This water would thus be used for sowing and final maturing of the Kharif crops and entire Rabi crops.
Irrigation oriented operation of the project gives the highest overall economic return. Thus the full live storage of 6.1MAF would be available for guaranteeing assured irrigation supplies throughout the year including replacement of the storage loss on the three existing reservoirs. Power
Kalabagh wit its installed capacity of 2400 MW (ultimate 3600 MW) would add to the system a very large chunk of cheap hydro-power..The energy generated at Kalabagh would be equivalent to 20 million of oil per year. CONSEQUENCES OF NOT BUILDING KALABAGH DAM
i) National food security would be jeopardized, thus subjecting the economy to additional burden of importing food grains.
ii) Loss of storage capacity of the on-line reservoir due to sedimentation would result in shortage of committed irrigation supplies causing serious dropeven in existing agriculture production. vi) Growth of domestic industrial and agriculture sectors would be impended due to...
