How the Cauvery water dispute between Karanataka and Tamil Nadu played out over the years, pre- and post-Independence
Bengaluru: The dispute over the sharing of Cauvery river water has lasted for more than a 150 years during which Karnataka and Tamil Nadu, the two main states involved, have accused each other of reneging on several agreements.
Historically, Karnataka had fewer irrigation systems than Tamil Nadu, both in terms of volume and sophistication, but the state played catch up to its southern neighbour’s numbers throughout the 20th century.
Karnataka expanded its irrigation facilities, increased the area under farming and changed cultivation patterns to grow water-guzzling rice and sugarcane in place of millets grown in arid conditions, which worried Tamil Nadu, according to historian Ramachandra Guha’s book India After Gandhi .
“Tamil Nadu feared that the frenetic canal building in the upper reaches threatened its farmers downstream. Karnataka argued that its late start should not preclude the fullest development of waters in its territory," Guha wrote.
After decades of wrangling that pulled in politicians, film actors and other prominent personalities apart from the common people of the two states, the Central government set up the Cauvery Water Dispute Tribunal in 1990 to resolve the issue.
The tribunal eventually submitted its final order to the government for approval in 2007 after 16 years of hearings, testimonies of 20 witnesses running into 10,000 pages, and representations made by the lawyers of Karnataka, Tamil Nadu and Kerala, the three main states involved, and Union Territory Puducherry.
The Tribunal awarded 419 tmc ft (thousand million cubit feet) of water for Tamil Nadu and 270 tmc ft for Karnataka. Kerala was awarded 30 tmc ft and Pondicherry 7 tmc ft.
Here’s a timeline of how the dispute played out over the years, pre- and post-Independence.
1892: The Cauvery river water dispute starts between what was then Madras Presidency (under the British rule) and the Princely state of Mysore. Madras seeks to restrain Mysore from building irrigation systems that would impede the flow of water from 15 rivers (the Cauvery, the Tungabhadra and the Pennar rivers and their tributaries)
1913: The Mysore government writes to Madras Presidency, seeking permission to build a reservoir. Madras, which plans to build a dam of its at Mettur, refuses consent. This leads to a dispute that results in the arbitration of July 1913. The arbitrator, H.D. Griffin, gives his decision in May 1914, allowing Mysore to go ahead with the construction of the dam up to 11 tmcft.
1915: Griffin’s decision is challenged by Madras. The secretary to the public works department (irrigation) writes to the government of India, disagreeing with the findings of Griffin. In the same year the Diwan of Mysore also challenges certain parts of the ruling.
1916: The government of India says it sees no reason to alter or amend the arbitrator’s award. Madras says it is unable “to acquiesce to the decision of the government of India" and escalates matters to the Secretary of State for India, who stops the arbitrator’s award. He, however, says Mysore is free to enter into talks with Chennai or approach a new tribunal.
1924: The dispute comes close to being resolved when Mysore and Madras reach an agreement under which Mysore is allowed to build a dam at Kannambadi village. The agreement is to be valid for 50 years and reviewed thereafter. Based on this agreement, Karnataka builds the Krishnaraja Sagar dam.
1929: An agreement is reached, meant to clarify the 1924 agreement allowing the construction of the Krishnaraja Sagar dam in Mysore and to specify exactly how much water would be released to Madras. Krishnaraja dam becomes functional in 1931 and the Mettur dam in 1934.
After India’s Independence, states are reorganized on the basis of language in 1956. Further disputes arise between Karnataka and Tamil Nadu over the former’s plan to build four more reservoirs across the four tributaries of the Cauvery.
August 1971: Tamil Nadu files a case in the Supreme Court asking that a tribunal be set up to adjudicate in the water dispute. That suit is withdrawn in 1972.
May 1972: Chief ministers of the two states decide to constitute the Cauvery Fact Finding Committee.
1974: The government of Karnataka says in 1974—the year the 1924 agreement expires after 50 years—that the 1924 and the 1892 agreements were in fact weighed against it because the then Madras Presidency was administered by the British, while Mysore was administered by the king of that state.

The 1991 interim order escalates tension between the states.
July 1991: Karnataka passes an ordinance in a move to nullify the interim awards.
The Supreme Court later steps in and strikes down the ordinance issued by Karnataka and upholds the tribunal’s award. In December, the Centre publishes the interim award in the Government of India gazette.
Karnataka Chief Minister S. Bangarappa responds by declaring a bandh in the state.
