Chennai, Sep 5 (IANS): Tamil Nadu Chief Minister J.Jayalalithaa has urged Prime Minister Narendra Modi to advise Karnataka to release the Cauvery river waters as per the orders of Cauvery Water Disputes Tribunal (CWDT).

In a letter to Modi on Friday, the text of which was released to the media on Saturday, Jayalalithaa complained of wilful default by Karnataka in not adhering to the schedule of release of Cauvery water as stipulated by CWDT in its final order dated February 5, 2007.

"The government of Karnataka, which is the upper riparian state, is duty-bound to ensure the stipulated monthly flows in 10 daily intervals during every water year, as per the final order of the Cauvery Water Disputes Tribunal, dated February 5, 2007," she said.

"I would like to bring to your notice that, as against the quantity of 94 TMC ft. of water due to Tamil Nadu at Billigundulu as per the final order of the Cauvery Water Disputes Tribunal, as on August 31, 2015, only a meagre quantity of 66.443 TMC ft. has been realised. Thus, there is a huge shortfall of 27.557 TMC ft," Jayalalalithaa said.

Urging Modi to intervene and advise Karanataka to make good the shortfall of about 27.557 TMC ft of water up to August 31, 2015, Jayalalithaa also pointed out to her repeated requests for the formation of the Cauvery Management Board and the Cauvery Water Regulation Committee.
