I. A No. 3 of 2008 filed by Tamil Nadu in Civil Appeal No. 2453/2007

Tamil Nadu filed the above I.A in Supreme Court regarding taking up of Shivanasamudram Hydro Electric Project by the State of Karnataka.                The State of Tamil Nadu insisted that the four Hydro Electric Schemes viz., Shivanasamudram, Mekedatu, Rasimalai and Hogenekal (the first two lie entirely in Karnataka area, whereas the other two lie in the common reach between Karnataka and Tamil Nadu)  be taken up as a joint venture by the Government of India and that Shivanasamudram and Mekedatu should not be  individually  taken up by the State of Karnataka. 

The replies to the above I.A have been prepared and approved by the Government. The same is to be finalized by the Senior Counsel       Sri. F.S. Nariman and has to be filed before the Supreme Court. 


Before the Cauvery River Authority:

          After the Final Award of the CWDT on 05.02.2007 Karnataka is of the opinion that neither the Interim Order nor the final order is under operation as the Tribunal in its interim order had stated that the interim order will be in effect till the final order is pronounced but the final order has not yet been notified by the Government of India, whereas Tamil Nadu is of the contention that the interim order dated: 25.06.1991 still survives.   

          The Government of India had indicated that till the final Order is notified, the interim order holds sway.   Karnataka has differed on this and has urged that the matter can only be resolved by CRA. 

          Under such circumstances, whether the regime of flows is to be regulated as per Interim order or as per final order remained unresolved.             As such during the year 2008-09 the regime of flows to be regulated to Tamil Nadu under distress condition was requested for from the CRA. In this respect several letters were addressed to Government of India to convene the CRA meeting at the earliest.  But till to date it is not been convened.   

          During the year the gaugings at Biligundlu have shown that a quantity of 199.96 tmc has flown to Tamil Nadu to end of 3/2009. The computations of Tamil Nadu at Mettur indicate the flow reaching Mettur as 195.55 tmc during the corresponding period.
