Inter-state river water disputes reflect the limits of cooperative federalism in India. Discuss with reference to the Cauvery dispute.

Water is a State subject (Entry 17, State List) while regulation of inter-state rivers rests with the Union (Entry 56), and Article 262 empowers Parliament to bar ordinary court jurisdiction — the framework under which the Inter-State River Water Disputes (ISRWD) Act, 1956 operates [1]. The Cauvery dispute shows how this design often strains federal comity rather than fostering it.

Federal fault lines exposed by the Cauvery dispute

• Prolonged adjudication: the dispute, traceable to colonial-era agreements of 1892 and 1924, went to a Tribunal in 1990, received a final award in 2007, and was settled in its present form only by the Supreme Court in 2018 [2] — negotiation repeatedly failed, litigation substituted for consensus.
• Weak enforcement teeth: the Cauvery Water Management Authority (CWMA), notified under Section 6A of the ISRWD Act and working with the CWRC under the Ministry of Jal Shakti [3], must depend on states operating their own reservoirs; its August 2026 direction of 9,000 cusecs for 15 days had to be defended before the Supreme Court [4].
• Continued judicialisation: despite Article 262, compliance returns to the apex court — Tamil Nadu pressing for an alleged balance of 17.604 tmc ft under the pro-rata formula [4].
• Competitive regionalism: recurring bandhs and farmer agitations turn an upper-riparian/lower-riparian question into an electoral one.
• Systemic, not exceptional: several tribunals remain functional on the Krishna, Mahadayi and Mahanadi, some pending for decades [5].

Where cooperative federalism still holds

• The CWMA–CWRC machinery, with all four riparian states represented, converts sharing into a routine, data-based seasonal exercise [3]; Karnataka's 2026 releases exceeded the ordered flow [4].
• The ISRWD (Amendment) Bill, 2019 proposes a Disputes Resolution Committee for negotiated settlement and a single tribunal with firm timelines [6].

Thus Cauvery reveals not the failure of federalism but its unfinished institutional design. Strengthening river basin organisations, real-time telemetry and transparent data-sharing, alongside greater use of the Inter-State Council, can shift disputes from courtrooms to negotiating tables — realising the "union of states" spirit that treats rivers as national, shared assets.
