The Krishna Water Disputes Tribunal-II in its final award, announced here on Thursday, has placed certain restrictions on the three riparian States in keeping with the assessment of the yearly yield of river waters on which the allocations were made.
The Tribunal allocated 1,001 thousand million cubic feet (tmcft) of Krishna waters to Andhra Pradesh, 911 tmcft to Karnataka and 666 tmcft to Maharashtra. In the KWDT-II award, the Tribunal decided to distribute the Krishna river waters yield at 65 per cent dependability which was assessed at 2293 tmcft. In KWDT-I, the water yield was assessed at 75 per cent dependability yield assessed at 2173 tmcft.
