Whose Water Is It Anyway: India's Endless Interstate River Disputes

Few conflicts in Indian public life have proven as durable as the fight over who gets how much water from a river that happens to cross a state boundary. The Cauvery dispute between Karnataka and Tamil Nadu, rooted in agreements dating back to 1892 and 1924 under British administration, has produced a tribunal award in 2007, a Supreme Court modification in 2018, an implementing authority created the same year, and periodic eruptions of street violence and political brinkmanship whenever monsoon rainfall falls short and Karnataka's reservoirs cannot release the water Tamil Nadu's farmers expect for their kuruvai crop. More than a century after the first agreement, the two states still negotiate the same fundamental scarcity through litigation and street protest rather than settled cooperation.

Why the tribunal model keeps underdelivering

The Interstate River Water Disputes Act of 1956 established the basic architecture still in use: when states cannot agree, the central government constitutes a tribunal to adjudicate and issue a binding award. In principle this should function similarly to arbitration in commercial disputes, producing a final, enforceable settlement. In practice, tribunals for major disputes including the Cauvery, Krishna, Godavari and Ravi-Beas rivers have taken anywhere from七 to over twenty years to issue awards, and even after an award is issued, implementation frequently drags through further Supreme Court litigation, as happened with the Cauvery award being challenged and partially revised over a further decade.

Several structural features explain the persistent underperformance. Tribunal awards are based on historical rainfall and usage data that can be decades old by the time a final award is issued, meaning the numbers being litigated may no longer reflect current agricultural cropping patterns, urban water demand, or climate variability. There is no permanent, technically staffed tribunal system; each dispute spawns its own ad hoc tribunal that must rebuild expertise and evidentiary record from scratch, contributing to the delays. And critically, enforcement mechanisms remain weak: a tribunal or even the Supreme Court can direct a state to release a specified volume of water, but has limited practical means to compel compliance against a state government that calculates, often correctly, that the domestic political cost of releasing water during a poor monsoon exceeds the cost of defying a judicial order, at least in the short term.

The politics of scarcity makes cooperation electorally risky

Water disputes in India are rarely just about hydrology; they are near-perfect vehicles for regional political mobilisation. Karnataka and Tamil Nadu politicians across party lines have found it consistently more electorally rewarding to be seen defending their state's water rights than to be seen negotiating a compromise, even when technical assessments suggest cooperative reservoir management could better serve both states' farmers than a rigid formula fought over in courtrooms. Every drought year reopens the wound, protests erupt in Bengaluru and Mandya, Tamil Nadu's assembly passes resolutions, and the cycle repeats with almost ritual predictability.

The unresolved Ravi-Beas dispute involving Punjab, Haryana and Rajasthan illustrates an even starker failure mode. Punjab's assembly unilaterally terminated all water-sharing agreements through legislation in 2004 following the Sutlej-Yamuna Link canal controversy, and the matter has remained substantially unresolved since, with the Supreme Court repeatedly directing Punjab to complete the canal's construction and Punjab repeatedly declining, calculating that the political cost within the state of releasing water to Haryana far outweighs any cost of continued contempt of court, an extraordinary situation in which a state government has essentially outlasted the enforcement patience of the country's highest judicial body for two decades.

What a functioning system would look like

Water experts, including several who have served on river boards, have long argued for consolidating dispute resolution into a single, permanent tribunal with standing technical staff, rather than repeatedly constituting new ad hoc bodies for each dispute, an idea partially reflected in amendments to the Interstate River Water Disputes Act passed in 2019 that aimed to create a single tribunal with multiple benches. Whether this structural fix will meaningfully accelerate outcomes remains to be tested, since the deeper problem, political incentives that reward defiance over compliance, is not something institutional redesign alone can solve.

A more promising avenue lies in shifting the underlying logic from zero-sum allocation to joint management, treating river basins as shared assets to be managed for combined welfare rather than divided assets to be split by formula. The River Basin Organisations that some countries use, coordinating irrigation scheduling, reservoir operation and drought response across an entire basin regardless of state boundaries, remain underdeveloped in India despite being recommended by numerous expert committees including the Mihir Shah committee on restructuring the Central Water Commission. Real-time data sharing on reservoir levels and rainfall, rather than reliance on decades-old historical baselines, could also reduce the information asymmetries that fuel mutual suspicion between states during drought years.

The counter-argument for state autonomy

Defenders of states' current bargaining position argue that water is fundamentally a state subject under India's constitutional scheme, and that federal or judicial overreach into water allocation risks eroding a hard-won constitutional balance, particularly for states like Punjab that view their water resources as tied to agrarian livelihoods already under severe stress from the groundwater crisis and stagnant farm incomes. There is legitimate force to the argument that any national reform of interstate water governance must preserve genuine state consultation rather than imposing centrally dictated formulas, especially given how contentious centre-state relations around agriculture have become in the years since the 2020 farm law protests.

But preserving state autonomy over water policy within a state's own borders is different from allowing indefinite non-compliance with judicial awards concerning water that must, by hydrological necessity, be shared across borders. India's rivers will keep flowing across the state lines that its administrative maps have drawn, and the choice is not between state autonomy and central control but between decades of unresolved litigation that serves no one's farmers well, and an institutional architecture patient and credible enough that a monsoon shortfall triggers cooperative rationing rather than another round of street protests and contempt petitions that have, by now, been rehearsed for over a generation.
