The bitterness between Orissa and Andhra Pradesh over sharing the water of river Mahendratanaya has reached flashpoint with the Andhra Pradesh government going ahead with its irrigation project. Andhra Pradesh chief minister, YS Rajasekhar Reddy, laid the foundation stone for the Rs 127-crore irrigation project across the Mahendratanaya in Srikakulam district recently. In retaliation, the Orissa government has decided to construct two diversion weirs for instant utilisation of water as an interim measure.
