Technically and politically "Kaala Bagh" dam is not feasible for the solidarity and unity of Pakistan.
On this issue, as a geo-political student we did a detailed research in Karachi University back in 1988. We conducted a conferrence and invited all the renowned geography and geology professors and technical experts from all over Pakistan.
The conclusion of that discussion was very clear and was agreed by all the experts even from NesPak MD and Professors of Punjab University, Lahore and Quad -e- Azam University, Islamabad.
On this issue. the technical points are as under:
1- N.W.F.P. concerns:
They have only an small area of Mardan, Naushahra and suroundings that is agricultural. The location of Kaala Baagh Dam is above of these areas. If water is stored in the dam then there are two negative impacts will occur on this agricultural land of NWFP.
a- Due to storage of the water, the underground water level of water will rise up, and it will develop salination in the Naushahra and surroundings. In few years this highly fertile land will be "SHOR ZADA" and dead.
b- If, by any reason, the dam is damaged (let's say air attacks from the enemy), the whole areas of Mardan, Naushahra and surroundings will be heavily flooded and these cities will turn to Moenjodaro.
1-Sindh concerns:
The river flows from mountains to the sea and during it's journey it brings all the minerals (they are required for the fertility of the land) from the mountains and distributes these minerals on the flat plains of agricultural lands. That's how River Indus (Darya -e- Sindh) leaves rich minerals on the Punjab's and Sindh's agricultural lands.
If a dam is built, then these minerals will set at the bottom of the dam and only shallow water (without minerals) will flow out of the dam. The province of Sindh has only one river that is river indus and if they get the filtered watered of River Indus then their agricultural land land will go imfertile eventually.
3-Political concerns:
The three provinces of Pakistan are afraid that Punjab will be in commanding position to release the waters to the other provinces and they have a fear that their generations to come will be slaves of one province.
(Right now, the same exercise India is doing against Pakistan. Indus Water Treaty in 1960 between Pakistan and India was a blunder. India has all the controls over each and every water)
These are all very valid reasons that Kaala Baagh Dam should not be built.
We can have other means to generate the power. The some are:
1- Coal mines in Thar
2- Atomic energy
3- Wind mills on Arabian Sea etc.etc.
Why we should emphasize on something that we will achieve at the cost of Pakistan's solidarity.
If we have other resources available then why we should go to the one which is not acceptable for every one in Pakistan.
