PROVINCIAL VIEWS ON MEGA DAMS


26/27

CONCLUSION

Water resources must be developed on prioritybasis

Feasibility study should be carried out of allpotential sites

The retention level of Kalabagh dam (915 ft) shouldbe further reduced to protect Peshawar valley fromwater-logging

Work on Basha dam, which is not controvercial,should be taken-up followed by Akhori andKatzarah
