In her letter to the Prime Minister, Ms Jayalalithaa mentioned that the Cauvery  River Authority last met on the 10th of February 2003 and its meeting was long overdue.

Recalling her request to the Prime Minister in her letter dated the 17th of October 2011, she said she had asked him to instruct the Ministry of Water Resources to notify the Final Order of the Cauvery Water Disputes Tribunal dated the 5th of February 2007 in the Gazette of India and place in position the Cauvery Management Board for the effective implementation of the Final Order of the Cauvery Water Dispute Tribunal.

Ms Jayalalithaa noted that however the Minister of Water Resources had informed her that it would be appropriate to consider notification of the order dated the 5th of February 2007 of the Cauvery Water Disputes Tribunal once the matter was disposed of by the Supreme court.

In her letter, Ms Jayalalithaa had brought to his notice that the Government of Karnataka was not ensuring release of water in the Cauvery as per the monthly pattern prescribed in the Interim Order in force or as per the Final Order of the Cauvery Water Disputes Tribunal, dated the 5th of February 2007, in the crucial months of June to September.

She further noted that the Government of Karnataka was unjustly utilising the water for summer irrigation within the state from February to May and depleting the storage in its 4 major reservoirs. The combined gross storage in the 4 major reservoirs of Karnataka as on the 1st of February 2012 was 58.50 TMC feet, Ms Jayalithaa mentioned. However, the combined gross storage in the 4 major reservoirs as on the 14th of May 2012 was only 28.176 TMC feet. The Government of Karnataka had depleted a storage of about 30.33 TMC feet from the 1st of Febrauary 2012 to the 14th of May 2012, besides utilizing the inflow of about 11 TMC feet. Thus, the total utilization from the 1st of February 2012 to the 14th of May 2012 by Karnataka was about 41 TMC feet, she observed.

Ms Jayalalithaa also added that due to depletion of storage during summer months, the Government of Karnataka impounded all the initial monsoon flows in its reservoirs and released water only when they start surplussing. This badly affected the inflows into the Mettur Dam, which consequently affects the Kuruvai crop very badly and also delays the cultivation of the Samba crop.

She said as the Prime Minister was aware, the finalization of the Distress Sharing Formula evolved by the Central Water Commission was eluding a solution which has ultimately deprived Tamil Nadu of adequate water which should have been released by Karnataka either as per the Interim Order of the Tribunal or by the formula evolved. The Cauvery Monitoring Committee in its 24th meeting had decided to refer the formula to the Cauvery River Authority for consideration when noticeable distress condition occured in future, she observed.

Such a distress situation may arise at any time, she warned. Ms Jayalalithaa added that there was another issue which required immediate consideration by the Cauvery River Authority. The Interim Order of the Cauvery Water Disputes Tribunal which is in force specified that the Government of Karnataka should not increase its area under irrigation beyond 11.20 lakh acres. 
Ms Jayalalithaa pointed out that the Government of Karnataka was not furnishing year wise details of the area under irrigation. In the circumstances, she requested the Prime Minister to convene the meeting of the Cauvery River Authority forthwith to decide the issues.
