Mahanadi Inter-State River Water Dispute
Why in the news
- The Chief Ministers of Chhattisgarh and Odisha discussed resolving the Mahanadi water dispute.
- Chhattisgarh stated that both States were willing to accept a decision facilitated by the Centre and the Central Water Commission.
- Opposition parties in Odisha questioned whether the State’s downstream interests would be adequately protected.
About the Mahanadi
- The Mahanadi originates in the Sihawa hills of Chhattisgarh and flows through Odisha into the Bay of Bengal.
- The Hirakud Dam in Odisha is a major multipurpose project on the river.
- Its basin supports irrigation, drinking-water supply, industry, hydropower and ecologically important coastal and delta regions.
Origin of the dispute
- Odisha argues that dams and barrages constructed upstream in Chhattisgarh reduce non-monsoon flows into Hirakud and the Mahanadi delta.
- Chhattisgarh maintains that a large part of the river’s catchment lies within its territory and that it is entitled to use the water for its development.
- Odisha invoked the Inter-State River Water Disputes Act in 2016. After negotiations failed, the Union government constituted the Mahanadi Water Disputes Tribunal in 2018. Ministry of Jal Shakti background
Constitutional framework
- Article 262 allows Parliament to provide for adjudication of inter-State river disputes.
- Entry 17 of the State List covers water, subject to Entry 56 of the Union List, under which Parliament can regulate inter-State rivers in the public interest.
- The Inter-State River Water Disputes Act, 1956 provides for tribunals when negotiations fail.
- The Central Water Commission is primarily a technical body; it is distinct from a statutory water-disputes tribunal.
Issues and way forward
- A settlement needs reliable real-time flow data, transparent project information and an agreed method for sharing lean-season water.
- Basin management must account for irrigation, urban demand, industrial use, environmental flows and climate variability.
- Political agreement may accelerate resolution, but it should be formalised through a legally durable and scientifically supported arrangement.
- The dispute illustrates cooperative federalism: rivers must be managed as common basins rather than exclusively as State resources.
