The Tamil Nadu government has approached the Supreme Court seeking urgent directions to restrain Karnataka from taking up summer irrigation and consequent depletion of storages in the reservoirs in Karnataka, in contravention of the final order passed by the Cauvery Water Disputes Tribunal in February 2007.

In its application, Tamil Nadu said the Tribunal in its final award on February 5, 2007 had allocated Kerala 30 tmc ft; Karnataka 270 tmcft; Tamil Nadu 419 tmcft and Puduchery seven tmcft out of the total 740 tmcft available for allocation.
