Centre extends Mahanadi Water Disputes Tribunal”s tenure by 9 months

# Mahanadi Tribunal Term Extended by 9 Months

**By Senior Legal & Environmental Correspondent, National Desk | April 11, 2026**

In a critical development for inter-state river water governance, the Central Government has officially extended the tenure of the Mahanadi Water Disputes Tribunal (MWDT) by an additional nine months. The extension, formalized by the Ministry of Jal Shakti on Saturday, April 11, 2026, aims to provide the judicial body sufficient time to finalize its comprehensive report and award regarding the contentious sharing of the Mahanadi River waters between the states of Odisha and Chhattisgarh.

This extension comes at a pivotal moment, as millions of farmers and diverse industrial belts across both states heavily depend on a fair, scientifically backed resolution to secure their agricultural and economic futures.

## The Anatomy of the Latest Extension

The Mahanadi Water Disputes Tribunal, headquartered in New Delhi, was originally constituted on March 12, 2018, following a directive from the Supreme Court of India. Under the framework of the **Inter-State River Water Disputes (ISRWD) Act, 1956**, a tribunal is generally mandated to submit its final report and decision within three years of its formation. However, owing to the immense complexity of hydrological data, cross-examinations, and the unprecedented delays caused by the global pandemic in previous years, the tribunal has required multiple extensions.

The latest notification from the Central Government invokes the provisions of Section 5(3) of the ISRWD Act, which allows the Centre to extend a tribunal’s term if it is deemed necessary to achieve a comprehensive and just resolution. With this nine-month extension, the MWDT is expected to conclude its final arguments, complete its assessment of the common basin model, and deliver a binding verdict by early 2027.

## Origins of the Mahanadi Conflict

The Mahanadi River is the lifeline of eastern central India. Flowing through the states of Chhattisgarh and Odisha before emptying into the Bay of Bengal, it sustains vibrant ecosystems, dense agrarian populations, and heavy industries. The seeds of the current dispute were sown in the late 20th century but escalated significantly in 2016.

Odisha raised severe objections to Chhattisgarh’s construction of a series of barrages and dams—including the Kalma, Basantpur, and Mironi barrages—across the upper catchments of the river. The Odisha government argued that these structures drastically restricted the flow of water into the Hirakud Dam, a multi-purpose project crucial for the state’s flood control, irrigation, and power generation.

Conversely, Chhattisgarh maintained a staunch defense. The state argued that a significant portion of the Mahanadi catchment area lies within its borders, yet historically, it had utilized only a fraction of the river’s potential. Chhattisgarh asserted that its barrages were essential to support local drinking water needs, irrigation for dryland farming, and a rapidly expanding industrial sector comprising thermal power plants and steel mills.

## Tribunal’s Progress: Assessing the Delays

The journey of the MWDT over the past eight years highlights the systemic challenges inherent in adjudicating inter-state river disputes in India. The tribunal, currently headed by Supreme Court judge Justice A.M. Khanwilkar (alongside two other judicial members), has had to navigate highly technical terrain.

The delays in arriving at a final award can be attributed to several critical factors:
* **Volume of Hydrological Data:** Both states have submitted thousands of pages of historical rainfall, water flow, and usage data. Reconciling discrepancies between the datasets provided by Odisha and Chhattisgarh requires independent expert verification.
* **Field Assessments:** The tribunal’s expert assessors have had to conduct multiple site visits across the massive Mahanadi basin, observing the physical impacts of the barrages during both the monsoon and the lean non-monsoon seasons.
* **Pandemic Interruptions:** The COVID-19 pandemic severely restricted physical hearings and field visits between 2020 and 2022, causing an unavoidable backlog.
* **Cross-Examination Procedures:** The legal representatives and technical experts from both states undergo rigorous, time-consuming cross-examinations to establish the validity of their claims regarding agricultural dependency and industrial demands.

## High Economic Stakes for Both States

The resolution of this dispute is not merely an exercise in legal semantics; it holds profound economic implications for both states.

In **Odisha**, the Hirakud Dam is central to the state’s agricultural output. During the non-monsoon months (the Rabi crop season), a steady flow of water from the upper catchment in Chhattisgarh is vital for paddy cultivation in western Odisha districts like Sambalpur, Bargarh, and Jharsuguda. Furthermore, the Mahanadi system provides critical drinking water to major urban centers, including Cuttack and the state capital, Bhubaneswar.

In **Chhattisgarh**, the economic narrative is driven by a late but aggressive push for industrialization and agricultural modernization. The state argues that as the upper riparian state, it has a sovereign right to harness the river’s potential to uplift its rural economy, particularly in districts like Raipur, Bilaspur, and Raigarh. Depriving Chhattisgarh of this water, its legal counsel argues, would stunt its economic growth and violate principles of equitable apportionment.

## Ecological and Environmental Concerns

Beyond the economic and political rhetoric lies a deeply concerning ecological dimension. Environmental scientists have repeatedly warned that the political wrangling over water volume ignores the ecological health of the river itself.

The reduced freshwater flow into the Mahanadi delta during the lean season has severe consequences for the region’s estuarine ecosystems. The delicate salinity balance of **Chilika Lake**—Asia’s largest brackish water lagoon—relies heavily on the freshwater discharge from the Mahanadi system. A reduction in this flow increases the lagoon’s salinity, directly threatening its unique biodiversity, including the Irrawaddy dolphins, and jeopardizing the livelihoods of thousands of traditional fisherfolk.

Furthermore, the mangrove forests of Bhitarkanika, which act as natural barriers against cyclones from the Bay of Bengal, depend on a specific ratio of fresh and saltwater. Any final award by the tribunal must theoretically account for “ecological flows” (e-flows)—the minimum water required to sustain the river’s natural ecosystems.

## Expert Perspectives on Inter-State Water Governance

Water policy analysts view the ongoing Mahanadi dispute as a textbook example of why India’s inter-state river water governance requires urgent legislative reform.

Dr. Anjali Deshmukh, a leading hydrologist and policy researcher at the Center for Policy Research, notes the limitations of the current framework. *”The granting of yet another nine-month extension highlights the procedural bottlenecks of ad-hoc tribunals. While the MWDT is doing incredibly thorough work, the lack of a standardized, permanent institutional mechanism means we rely on adversarial litigation rather than cooperative basin management. The final award must not only divide the water but also establish a joint, depoliticized board to monitor river health year-round,”* she stated.

Legal experts also point out that under Article 262 of the Indian Constitution, the Supreme Court does not have direct jurisdiction over inter-state river disputes, placing the entire burden of resolution on these specially appointed tribunals. The final award, once published in the official gazette, carries the same legal weight as an order of the Supreme Court.

## Future Outlook: The Crucial Nine Months Ahead

With the clock resetting for another nine months, the Mahanadi Water Disputes Tribunal enters what is likely its final and most crucial phase. The upcoming months will be dominated by the conclusion of final arguments by the legal teams representing both Odisha and Chhattisgarh.

Key takeaways for the immediate future include:
1. **Data Consolidation:** The tribunal will finalize the “yield” of the river basin—a mathematically agreed-upon figure representing the total available water at different dependability levels (typically 75% dependability).
2. **Equitable Apportionment:** The final award will lay down specific volume allocations (in Thousand Million Cubic feet – TMC) for both states, distinguishing between monsoon abundance and non-monsoon scarcity.
3. **Institutional Mechanisms:** It is highly anticipated that the tribunal will mandate the creation of a permanent Mahanadi River Management Board (MRMB) to implement its decision, monitor the barrages in Chhattisgarh, and ensure the mandated flow reaches the Hirakud reservoir in Odisha.

As climate change continues to alter monsoon patterns—bringing intense, erratic rainfall followed by prolonged dry spells—the rigid mathematical division of river waters is becoming increasingly difficult. The resolution of the Mahanadi dispute will set a significant legal and environmental precedent for how modern India manages its increasingly scarce natural resources amidst rapid regional development. For the millions living in the Mahanadi basin, the end of this nine-month extension cannot come soon enough.
