 Kishau Multipurpose Project Agreement Strengthens Upper Yamuna Water Security and Supports Yamuna Rejuvenation

Recent Developments:

• On 15 September 2026, six Yamuna-basin participants, Himachal Pradesh, Uttarakhand, Uttar Pradesh, Haryana, Rajasthan and Delhi, signed an agreement in New Delhi to advance the long-pending KishaMultipurpose Project. The agreement followed the consensus reached in June 2026 and was signed in the presence of the Union Home Minister and Union Jal Shakti Minister.
• The project had remained stalled for about eight years, mainly because of disagreements over cost-sharing, water allocation and the distribution of project benefits and burdens. The latest agreement creates a framework for resolving these concerns through greater Central financial assistance and a revised benefit-sharing arrangement.
• The project will now proceed towards Union Cabinet approval. The Centre has agreed to bear 90% of the cost of the water component, while the remaining 10% will be shared by the six participating states.

What is the KishaMultipurpose Project?

Location and River:

• The KishaMultipurpose Project is a proposed storage and hydropower project on the Tons River, a major tributary of the Yamuna River.
• The project site lies along the Himachal Pradesh–Uttarakhand border, covering the Sirmaur district of Himachal Pradesh and Dehradun district of Uttarakhand. The project is being implemented through KishaCorporation Limited, a joint venture of the governments of Himachal Pradesh and Uttarakhand.

Major Project Features:

• The proposed structure is a 232.6-metre-high concrete gravity dam, making it a major storage intervention in the Upper Yamuna basin.
• The current project documentation provides for a 660 MW hydropower capacity, comprising four units of 165 MW each, with hydropower generation treated as an incidental benefit of the storage project.
• The project is designed to provide about 1,324 million cubic metres (MCM) of live water storage, support irrigation over approximately 97,076 hectares, and provide water for drinking and industrial requirements.
• The project is expected to generate substantial clean hydropower, with official project documentation estimating about 1,379 million units, while the latest government communication cites approximately 1,476 million units of annual generation; the variation reflects differences in project-stage estimates and documentation.

Why is the Project Important?

Upper Yamuna Storage Deficit:

• The KishaProject is significant because the Upper Yamuna basin historically lacked adequate storage infrastructure between the Yamunotri region and the Okhla Barrage.
• The project is therefore intended to regulate seasonal water availability by storing monsoon flows and releasing water in a controlled manner for irrigation, drinking water, industrial use and downstream river requirements.

Link with the 1994 Upper Yamuna Agreement:

• The project is linked to the 1994 MoU on the sharing of Yamuna waters among the basin states. The agreement established a framework for allocating the utilisable waters of the Upper Yamuna among the participating states.
• The original arrangement involved undivided Uttar Pradesh, Haryana, Rajasthan, Himachal Pradesh and Delhi. After the creation of Uttarakhand in 2000, Uttar Pradesh's allocation was subsequently divided between Uttar Pradesh and Uttarakhand.
• The Upper Yamuna storage strategy envisaged three major projects, namely Kishau, Lakhwar and Renukaji, to improve regulated water availability in the basin. The KishaProject therefore forms part of a broader basin-level water-management approach rather than being an isolated dam project.

Water Security for Northern India:

• The project is expected to strengthen water availability for Haryana, Uttar Pradesh, Rajasthan, Delhi and Uttarakhand, while its location in the Himalayan region gives it importance for downstream water regulation.
• Rajasthan's allocation is particularly relevant for water-stressed areas such as the Shekhawati region, where additional water availability can support drinking-water and irrigation requirements.

Inter-State Cost-Sharing Dispute:

Himachal Pradesh's Concerns:

• The principal obstacle to the project's progress was the disagreement over how the financial burden should be distributed among the participating states.
• Himachal Pradesh had raised concerns because the project involves submergence and displacement within the upstream area, while a substantial proportion of its water benefits would accrue to downstream states.
• The state also questioned the earlier expectation that it should bear a significant portion of the power-component cost, particularly when the downstream states would receive substantial water benefits.

2026 Resolution Mechanism:

• In June 2026, the Centre proposed to finance 90% of the water component, substantially reducing the financial burden on the participating states.
• A separate arrangement was created for Himachal Pradesh under which its allocated water would be transferred to Delhi and Rajasthan, while these two states would share the cost of Himachal Pradesh's portion of the power component.
• The arrangement therefore attempts to align costs with actual benefits, allowing Himachal Pradesh to receive compensation for its contribution while downstream states obtain additional water resources.

Water Allocation and Benefits:

Storage and Water Distribution:

• Under the latest arrangement, the principal storage allocations are approximately Haryana — 633 MCM, Uttar Pradesh — 411 MCM, Rajasthan — 124 MCM, Delhi — 80 MCM and Uttarakhand — 34 MCM, while Himachal Pradesh's allocated share is subject to the agreed transfer mechanism.
• The project is also intended to provide drinking and industrial water, besides supporting irrigation and regulated downstream flows.

Yamuna Rejuvenation:

• The project has acquired additional significance because its regulated releases are expected to increase water availability in the Yamuna, particularly during periods when natural flows are relatively low.
• The Union Government has explicitly linked the project with the broader objective of a cleaner and rejuvenated Yamuna, making the project relevant to river-basin management as well as conventional irrigation and hydropower planning.

Significance for Cooperative Federalism:

Inter-State Water Governance:

• Rivers cross administrative boundaries, making inter-state coordination essential for their effective management.
• The Kishaagreement demonstrates how financial restructuring, negotiated benefit-sharing and Central assistance can help participating states move towards consensus on a complex water-infrastructure project.
• The project also illustrates the importance of institutions such as the Central Water Commission, Ministry of Jal Shakti and Upper Yamuna River Board in coordinating water allocation and infrastructure planning across state boundaries.

National Project Framework:

• The KishaProject has been treated as a National Project, under which the Centre provides substantial financial assistance for the water component. KishaCorporation's project documentation records the declaration of the project as a National Project in 2008.
• Such Central support can reduce the financial constraints faced by Himalayan states while enabling downstream states to receive the benefits of basin-level water infrastructure.

Environmental and Social Concerns:

Submergence and Rehabilitation:

• Large storage projects can create significant submergence, displacement and livelihood impacts, particularly in ecologically sensitive Himalayan areas.
• Earlier assessments indicated substantial land submergence and impacts on settlements in Himachal Pradesh and Uttarakhand. Therefore, land acquisition, rehabilitation and resettlement must remain integral to project implementation.

Himalayan Ecology:

• The project area forms part of a fragile Himalayan environment where construction activity can interact with slope instability, landslides, biodiversity loss, sedimentation and downstream ecological flows.
• Environmental Impact Assessment and Environmental Management Plans should therefore examine cumulative impacts rather than assessing the dam only as an individual infrastructure project.

Balancing Development and Ecology:

• The project highlights the wider policy challenge of balancing water security, renewable energy and irrigation requirements with environmental sustainability and community rights.
• Effective implementation should maintain adequate environmental flows, strengthen disaster-risk management and ensure transparent rehabilitation of affected communities.

Way Forward:

Basin-Level Planning:

• The KishaProject should be implemented as part of an integrated Upper Yamuna basin-management strategy, with coordinated planning for Kishau, Lakhwar and Renukaji.

Sustainable Implementation:

• Project authorities should ensure scientifically robust seismic and geological assessments, environmental-flow management, catchment-area treatment, sediment management and climate-resilient dam design.

Cooperative Federalism:

• The new cost-sharing framework should be supported by transparent mechanisms for water accounting, benefit sharing, dispute resolution and monitoring, reducing the possibility of renewed inter-state disagreements.

Rehabilitation and Local Participation:

• Communities affected by submergence should receive timely compensation, rehabilitation, livelihood restoration and social infrastructure, with local participation incorporated into implementation.

Value Addition for UPSC:

Key Concept — Cooperative Federalism in Water Governance:

• The KishaProject illustrates how inter-state water disputes can be addressed through negotiated benefit-sharing, Central financial assistance and basin-level planning rather than relying exclusively on adjudication.

Mains-Ready Line:

• “The Kishaagreement demonstrates that India's water-security challenge is not merely one of water scarcity but also of storage, distribution, institutional coordination and equitable benefit-sharing across federal boundaries.”
