The long-standing dispute over the sharing of Mahanadi river water between Chhattisgarh and Odisha has entered a decisive phase. The central government has extended the tenure of the Mahanadi Water Dispute Tribunal by nine months, pushing its deadline to January 13, 2027. This extension has renewed expectations that a final judgment may soon bring clarity to one of India’s most complex inter-state water conflicts.

Origin of the Dispute and Historical Background

The roots of the conflict date back to 1983, when the present-day state of Chhattisgarh was part of Madhya Pradesh. At that time, the disagreement over river water allocation was primarily between Madhya Pradesh and Odisha. Over the years, administrative changes, state reorganization, and increasing water demand transformed the issue into a prolonged legal and political battle between Chhattisgarh and Odisha.

Growing Tensions and Failed Negotiation Attempts

Several attempts were made to resolve the dispute through dialogue and negotiation mechanisms. A dedicated negotiation committee was formed by the central government, which submitted its report in May 2017. However, the talks failed to produce consensus, largely due to disagreements and lack of full participation from all stakeholders. This failure ultimately paved the way for judicial intervention.

Formation of the Tribunal and Legal Proceedings

Following the breakdown of negotiations, the central government constituted the Mahanadi Water Dispute Tribunal in March 2018 under the Inter-State River Water Disputes Act, 1956. The tribunal was tasked with examining claims, studying hydrological data, and recommending a fair water-sharing formula between the two states.

Delays and Operational Challenges

The tribunal’s progress has repeatedly been slowed by multiple setbacks. Administrative issues, lack of quorum, and leadership changes, including the resignation of former chairman A. M. Khanwilkar, significantly affected proceedings. Additionally, the COVID-19 pandemic further delayed hearings and field investigations, forcing multiple extensions of the tribunal’s timeline.

Ground Inspections and Technical Assessment

To ensure a fair evaluation, the tribunal conducted detailed field visits across key regions, including Raipur, Bilaspur, and Korba. The inspection covered major water infrastructure projects on the Mahanadi and Hasdeo rivers. Officials from both states provided extensive technical data and hydrological records to support their respective claims.

Importance of Mahanadi River for Both States

The Mahanadi river plays a critical role in the economic and social structure of both states. In Chhattisgarh, it is widely regarded as a lifeline for agriculture and drinking water supply. In Odisha, the river is essential for irrigation, hydroelectric power generation, and industrial operations. Any final decision will therefore have far-reaching consequences for development and resource management.

Extension of Tribunal and Expectations for 2027 Verdict

The recent extension of the tribunal’s tenure signals that the case is moving closer to conclusion. With most technical assessments completed and field data already collected, expectations are rising that a final verdict may be delivered in early 2027. The decision is likely to shape water-sharing policies and long-term inter-state relations between Chhattisgarh and Odisha.
