What is the Kishau Dam Accord?
The Kishau Dam Accord is a multi-state agreement signed in August 2024 to construct the Kishau multi-purpose project on the Tons River (a major tributary of the Yamuna) in Uttarakhand. The accord brings together Uttarakhand, Himachal Pradesh, Haryana, Uttar Pradesh, Rajasthan, and Delhi to share water and power benefits for drinking, irrigation, and hydroelectricity. This project is envisioned as a lasting solution to the Yamuna's water scarcity and ecological degradation.
Quick Definition: The Kishau Dam Accord is a water-sharing pact among six states to build a 236-metre-high concrete gravity dam on the Tons River, aiming to store 1.7 billion cubic metres of water and generate 660 MW of hydroelectric power, while rejuvenating the Yamuna.
Background and Need for the Kishau Dam
The Yamuna basin, covering 3,66,223 sq km, supports over 57 million people but suffers from acute water stress and pollution. The 2022 Central Pollution Control Board report highlighted that the Yamuna's Biochemical Oxygen Demand (BOD) levels exceed permissible limits by 3-4 times in several stretches. Climate change-induced glacial melt and erratic monsoons further threaten the river’s lean season flow.
Why the Accord Became Urgent
- Drinking water crisis in Delhi: The capital depends on Yamuna for 70% of its water needs, yet receives less than half the required ecological flow.
- Irrigation deficit: Haryana and Uttar Pradesh face increasing agricultural water demand, with groundwater tables falling rapidly.
- Political deadlock: Since the 1994 Yamuna Water Sharing Agreement, states failed to agree on new storage projects until the Supreme Court’s intervention pushed for the Kishau dam.
Key Features of the Kishau Dam Accord
The accord embodies the principle of cooperative federalism in water governance. Here are the salient points that every aspirant must know:
- Project Location: Near Kishau village on Tons River, Uttarakhand-Himachal border.
- Dam Type: 236 m high concrete gravity dam – one of the tallest in India.
- Storage Capacity: 1.7 billion cubic metres (BCM) of live storage.
- Hydropower: 660 MW installed capacity, shared among partner states.
- Water Supply: 1,043 million cubic metres (MCM) annually for drinking and irrigation.
- Yamuna Flow Augmentation: Releases 1.2 BCM of water downstream during non-monsoon months to maintain ecological flow.
- Cost Sharing: ₹18,000 crore project cost divided as per water and power benefit ratios.
Six Participating States and Their Shares
The water-sharing formula, a triumph of negotiation, allots Yamuna waters based on basin area, population, and drought vulnerability. The power allocation follows a different ratio to ensure equity.
| State | Water Share (%) | Hydropower Share (%) |
|---|---|---|
| Haryana | 38.2% | 30.5% |
| Uttar Pradesh | 33.6% | 28.7% |
| Rajasthan | 15.8% | 20.1% |
| Delhi | 9.8% | 12.4% |
| Uttarakhand | 2.2% | 5.3% |
| Himachal Pradesh | 0.4% | 3.0% |

How the Kishau Dam Will Rejuvenate the Yamuna
The dam’s design directly addresses the Yamuna’s two biggest threats: lean season flow depletion and high pollution load. Here's the mechanism:
Step-by-Step Rejuvenation Process
- During monsoon, the dam stores excess water that would otherwise cause floods.
- In dry months, a minimum of 15 cumecs (cubic metres per second) is released from the reservoir to maintain the Yamuna’s environmental flow.
- This sustained flow dilutes pollutants, raising dissolved oxygen levels and supporting aquatic life.
- Reduced dependence on groundwater in Haryana and UP recharges aquifers.
- Improved water quality benefits Delhi’s water treatment plants, reducing treatment costs and health risks.
As per the National Institute of Hydrology, the rejuvenation plan can restore the river’s self-purification capacity by 40% within five years of operation.
Benefits of the Kishau Dam Project
Beyond Yamuna rejuvenation, the project delivers multifaceted benefits that make it a national priority.
- Drinking Water Security: 550 MCM dedicated to drinking water, safeguarding urban centres like Delhi, Dehradun, and Chandigarh.
- Irrigation Boost: 493 MCM for irrigation, stabilising kharif and rabi crops over 2.5 lakh hectares.
- Green Energy: 660 MW hydroelectricity contributes to India's 500 GW renewable energy target by 2030.
- Flood Control: Reduces monsoon flood peaks in the Yamuna-Hindon plains, protecting lakhs of people.
- Tourism and Employment: Reservoir area to become a hub for eco-tourism, generating 15,000 direct jobs during construction.
Environmental and Social Challenges
No large dam is without concerns. The Kishau project faces significant hurdles that require transparent governance.
Environmental Concerns
- Submergence: 1,800 hectares of forest land, including parts of Govind Wildlife Sanctuary, will be submerged.
- Biodiversity Loss: Habitat of the endangered snow trout and the Western Tragopan bird.
- Seismic Risk: The region falls in Seismic Zone IV-V, demanding robust engineering.
- Sedimentation: High silt load from the young Himalayas could reduce reservoir life.
Social and Rehabilitation Issues
Approximately 2,500 families face displacement. The accord mandates a comprehensive Resettlement and Rehabilitation (R&R) plan with land-for-land compensation, but past experiences (Tehri, Sardar Sarovar) call for vigilant oversight.
Expert View: “The Kishau project is a textbook case of balancing development and environment. Its success hinges on strict implementation of the Environmental Management Plan and genuine participatory rehabilitation,” says Dr. Rina Sharma, Water Policy Researcher at IIT Roorkee.
Kishau Dam vs Other Inter-State Water Agreements
India has a rich history of river accords. The Kishau agreement stands out for its inclusivity and forward-looking clauses.
| Feature | Kishau Accord (2024) | Yamuna Water Agreement (1994) | Cauvery Water Disputes Tribunal |
|---|---|---|---|
| Parties | 6 states | 5 states | 4 states, 1 UT |
| Primary Goal | Storage + rejuvenation | Allocation of existing flow | Adjudication of dispute |
| Ecological Flow | Mandated 15 cumecs | Not specified | Not addressed |
| Hydropower Component | 660 MW shared | None | None |
| Climate Resilience | Built-in adaptive management | Absent | Absent |
This comparison highlights why the Kishau model is being studied for future Ganga and Godavari basin agreements.
