Karnataka government to protect livelihood of farmers, abide by law on releasing Cauvery water to Tamil Nadu
The state government reiterated that it will protect the livelihood of farmers while abiding by its legal obligation to release Cauvery river water to Tamil Nadu.
The government reaffirmed its commitment to the Mekedatu balancing reservoir and drinking water project as a long-term solution to recurring water-sharing tensions in the Cauvery basin.
The statement came amid directions from the Cauvery Water Management Authority's regulatory mechanism for water release from Karnataka's reservoirs during periods of distress.
A separate bill concerning the regulation of public property usage was also taken up by the state government during the same period.
Cauvery Water Disputes Tribunal Award and the Cauvery Water Management Authority
The Cauvery Water Disputes Tribunal (constituted under the Inter-State River Water Disputes Act, 1956) delivered its final award on February 5, 2007, allocating the 740 TMC of dependable annual flow among the basin states — Tamil Nadu 419 TMC, Karnataka 270 TMC, Kerala 30 TMC, Puducherry 7 TMC, with 14 TMC reserved for environmental protection. The Supreme Court, in its 2018 judgment in State of Karnataka v. State of Tamil Nadu, modified the Tribunal's allocation (revising Karnataka's release obligation from 192 TMC to 177.25 TMC) and directed the Centre to constitute an implementing mechanism. Accordingly, the Cauvery Water Management Scheme was notified on June 1, 2018, creating the Cauvery Water Management Authority (CWMA) and the Cauvery Water Regulation Committee (CWRC) under Section 6A of the Inter-State River Water Disputes Act, 1956.
Key Details
- CWDT final award: February 5, 2007; gazetted by the Centre on February 19, 2013
- Supreme Court judgment: State of Karnataka v. State of Tamil Nadu (2018) — reduced Karnataka's release obligation to 177.25 TMC, invoking the principle that inter-state river waters are a "national asset" and no single state can claim exclusive ownership
- CWMA constituted June 1, 2018, under Section 6A of the Inter-State River Water Disputes Act, 1956; headquartered in New Delhi under the Ministry of Jal Shakti
- CWMA composition: a Chairperson (senior engineer/IAS officer of Secretary/Additional Secretary rank, 5-year term), two full-time Members (Water Resources and Agriculture), two part-time Central Government Members, and four part-time Members representing Karnataka, Tamil Nadu, Kerala, and Puducherry
- CWRC handles day-to-day monitoring and regulation of actual water release, reporting to the CWMA
When the state government speaks of a "legal obligation" to release water, it refers to compliance with the CWMA/CWRC's monthly and cumulative release schedules, which operationalise the Supreme Court-modified Tribunal award — a quasi-judicial, technical mechanism distinct from ordinary executive discretion.
Inter-State River Water Dispute Resolution Mechanism — Article 262
Article 262 of the Constitution empowers Parliament to legislate for adjudication of disputes relating to the use, distribution, or control of inter-state river waters. Under this power, Parliament enacted the Inter-State River Water Disputes Act, 1956, which provides for the constitution of ad hoc tribunals (like the CWDT) to adjudicate such disputes referred by the Centre, and — importantly — bars the jurisdiction of the Supreme Court and other courts over these disputes once a tribunal is constituted, under Article 262(2).
Key Details
- Article 262(1): Parliament may provide for adjudication of inter-state river water disputes by law
- Article 262(2): Parliament may by law exclude the jurisdiction of the Supreme Court or any other court in respect of such disputes — a departure from the Supreme Court's ordinary original jurisdiction over inter-state disputes under Article 131
- Inter-State River Water Disputes Act, 1956 (amended 2002 and 2019) operationalises Article 262(1); the 2019 amendment proposed a single standing tribunal with multiple benches instead of a fresh tribunal for each dispute
- Cauvery basin states involved: Karnataka, Tamil Nadu, Kerala, Puducherry (Union Territory)
Despite the constitutional bar under Article 262(2), the Supreme Court has in practice entertained appeals on the CWDT award (as it did in 2018) by treating them as questions on the correctness/interpretation of the award rather than a fresh "water dispute" — a nuance frequently tested regarding the limits of Article 262(2).
The Mekedatu Balancing Reservoir Project
Mekedatu is a proposed multi-purpose balancing reservoir-cum-drinking water project at the confluence of the Cauvery and Arkavathi rivers in Kanakapura taluk, Ramanagara district, Karnataka, roughly 100 km from Bengaluru. First announced in 2013, the project envisages a dam approximately 99 metres high impounding about 67.16 TMC of water, primarily to secure Bengaluru's drinking water supply and regulate downstream releases during distress years, with an associated ~400 MW hydropower component.
Key Details
- Location: confluence of Cauvery and Arkavathi rivers, Kanakapura taluk, Ramanagara district, Karnataka
- Proposed storage: ~67.16 TMC; dam height ~99 metres
- Dual purpose: drinking water security for Bengaluru/Ramanagara + ~400 MW hydroelectric generation
- Tamil Nadu's objection: the project was never approved under the CWDT Final Award and could alter the lower riparian state's assured share; the Supreme Court has treated Tamil Nadu's challenge as premature pending Karnataka's Detailed Project Report (DPR) process and requisite central clearances
The state government's reaffirmed commitment to Mekedatu links directly to the broader Cauvery water-sharing dispute — Karnataka frames the project as a mechanism to smoothen inter-annual variability in water availability while still meeting its CWMA-mandated release obligations to Tamil Nadu.
- CWDT final award: February 5, 2007 (740 TMC total dependable flow allocated)
- Karnataka's Cauvery share (Tribunal): 270 TMC; Tamil Nadu: 419 TMC; Kerala: 30 TMC; Puducherry: 7 TMC; environment: 14 TMC
- 2018 Supreme Court modification: Karnataka's release obligation revised to 177.25 TMC (from 192 TMC)
- CWMA and CWRC constituted: June 1, 2018, under Section 6A, Inter-State River Water Disputes Act, 1956
- Mekedatu project: ~67.16 TMC storage, ~99 m dam height, ~400 MW proposed hydropower capacity
- Constitutional basis for dispute resolution: Article 262(1) and (2); statutory basis: Inter-State River Water Disputes Act, 1956
