Cauvery Dispute: Background, Timeline, Recent Verdict, Issues
- The river Cauvery is the third largest river of South India after Mahanadi and Godavari. Its water drains the states of Karnataka and Tamil Nadu. But the sharing of the water of this river has become an issue of conflict between the two states, with each referring to a British-era document for deciding their claim.
Geographical Location of the River:
- The Cauvery River originates in Karnataka’s Kodagu district, flows into Tamil Nadu, and reaches the Bay of Bengal at Poompuhar.
- Parts of three Indian states – Tamil Nadu, Kerala, and Karnataka – and the Union Territory of Pondicherry lie in the Cauvery basin.
- The total catchment area is 81,155 square kilometres. Off the total area 34,273 kilometres is in Karnataka, 44,016 square km in Tamil Nadu and Puducherry and about 2,866 sq km is in Kerala.
- The river’s upper hilly catchment lies in Karnataka and Kerala. Its lower part lies in the plains of Tamil Nadu.
- Karnataka is the upper riparian statewhere the river originates; Tamil Nadu is a lower riparian state.
Brief Background of the Dispute
- In mid-19thcentury, the government of Mysore wanted to build a number of new irrigation projects.
- This caused anxiety to the state of Madras which was dependent on Cauvery waters for irrigation.
- After several rounds of discussions between the two and the government of India, an agreement was signed in 1892
- Another agreement was signed in 1924,relating to the use, distribution, and control of the Cauvery waters specifically.
- Both agreements stated that existing irrigation should not be impeded by the construction of new works upstream, and downstream irrigation should not be reduced.
- However, Karnataka did not implement these agreements
- In 1910, the government of Mysore proposed a reservoir at Kannambadi, and sought the consent of the Madras government under the 1892 agreement.
- As the Madras government did not agree, it was referred to arbitration.
- The Madras government did not accept the reward of the arbitration panel and it appealed. When the government of India did not intervene, moves were initiated that led to the signing of the 1924 Agreement.
- As Kerala and Puducherry also claimed share of Cauvery water after India attained Independence, a Fact Finding Committeewas set-up in 1970 to figure out the situation on ground.
- After submission of the report, the states reached at an agreement in 1976.
- However, later when Tamil Nadu got its new government, it refused to give consent to terms of agreement which led to fresh disputes.
- In 1986, Tamil Nadu government appealed the Central government to constitute a tribunal for solving the issue under Inter-State Water Disputes Act, 1956.
- The Centre constituted the Cauvery Water Disputes Tribunal (CWDT) finally in 1990 to resolve the dispute following a Supreme Court order.
- The Tribunal announced its final order in 2007
- The award made an annual allocation of 419 TMC to Tamil Nadu in the entire Cauvery basin, 270 TMC to Karnataka, 30 TMC to Kerala, and 7 TMC to Puducherry.
- Karnataka had contested the final verdict of the dispute tribunals, arguing that a major share of the water will go to Tamil Nadu, leaving almost six Karnataka districts, including Bengaluru, without enough water for drinking and farming.
- Over the years, the Supreme Court has passed a series of orders setting a limit to the amount of water to be released by Karnataka to Tamil Nadu.
- In 2016, the Tamil Nadu government sought the Supreme Court’s intervention claiming that Karnataka had failed to fully comply with a series of orders passed by the court regarding timely release of water from the Cauvery River.
- Karnataka argued that it was unfair to require the state to release a fixed amount of water irrespective of the availability of water. The state also made strong case on drinking water needs of Bengaluru
Timeline of the Dispute:

- 1991-The Tribunal rejected the plea for interim relief of the Tamil Nadu government against which the state went on an appeal to the Supreme Court. The Supreme Court then directed the tribunal to entertain the interim relief petition. The tribunal complied and passed an interim award which required Karnataka to release 205 tmcft of water. But in order to nullify the effects of the interim award the Karnataka government passed an ordinance that also became a matter of litigation and was struck down by the Supreme Court. But Karnataka still refused to obey which resulted in the publication of notification of the interim award in gazette of Government of India.

- 2002-This became another major eventful year which began with the Authority directing Karnataka to release only 0.8 tmcft of water, which angered Tamil Nadu and it again appealed to the Supreme Court. Meanwhile, a lot of political events unfurled with a Congress MP from Tamil Nadu blaming the AIADMK government for not sufficiently addressing the issue in the Parliament which led to a tussle between the two parties. In Karnataka a farmer jumped into the Kabini reservoir and died in protest against the release of water to Tamil Nadu. Then a Cauvery Monitoring Committee Panel was formed that visited the farmers of Karnataka seeking to know their distress.

Karnataka government refused to obey the interim award.
- After 16 years of hearing and an interim order, the Tribunal announced its final order in 2007 allocating 419 tmcft water to Tamil Nadu and 270 tmcft to Karnataka. Kerala was given 30 tmcft and Puducherry got 7 tmc ft. Both Karnataka and Tamil Nadu filed review petitions in Supreme Court.
