This again proves your lack of knowledge of the terrain in KN. Yes, agri is harder than the plains. Does that mean that water should be exclusive to plains. What TN govt does in Dharmapuri and elsewhere in TN is its choice. Certainly cannot argue that water should be denied because of that. Just look at Mandya before irrigation and after irrigation. It was just about any other arid region that has been converted to a good agricultural land. Similar is the case with Bangalore rural, hassan, Tumkur as well. Only if water is made available. May be Dharmapuri can learn a lesson here about agriculture in arid areas. It is intent that is important - whether you are willing to share whatever is there in the river. Not about denying rights to co-riparian states because one has started using waters earlier than the other. BTW, this is in response to your comments on rocky terrain in South Karnataka
