Power generation is a must for Pakistan, so these projects can't be discarded. But creating a dam for purposes of water storage is no easy feat, and it depends on where you will construct it. Sometimes the natural terrain does not offer much. How ever, what should be done is a detail topographical survey of all areas where dams can be built and then decide which ones are the best one. Places like GB, AJK and KPK have huge mountain ranges, gorges and deep river flows and thus we need to map them. We haven't built big dams in a long long period. So anything right now is a win-win situation, especially international donors and agencies willing to shell out money.
