Kishau Multipurpose Dam Project
Why in News?
In a major breakthrough on 16 June 2026, a consensus was reached among six northern states to sign a critical Memorandum of Understanding (MoU) to execute the long-pending Kishau Multipurpose Dam Project.
Overview and Location
- River and Tributary: The project is designed across the Tons River, which is the largest tributary of the Yamuna River and forms the natural geographic border between Uttarakhand and Himachal Pradesh.
- Exact Site: The structure will be built at Samberkhera, situated roughly 10 km upstream of the existing Ichari Dam and 50 km upstream of Dakpathar.
- National Importance Status: Acknowledging its massive regional scale, the Government of India officially declared it a National Project in 2008.
Technical and Engineering Specifications
- Dam Architecture: The blueprints call for a massive 236-metre-high concrete gravity dam (specifically utilising Roller Compacted Concrete).
- Projected Financial Layout: The updated execution cost of the mega-dam is estimated at approximately ₹15,000 crore.
- Reservoir Live Storage: It will carve out an enormous reservoir capable of holding 1,324 million Cubic Meters (MCM) of live water capacity.
- Hydroelectric Capacity: A dam-toe powerhouse on the left bank of the river will boast an installed capacity of 660 Megawatts (MW), generating 1,379 million Units (MU) of clean electricity annually.
Joint Venture Management
- Kishau Corporation Limited: A dedicated 50:50 joint venture company was registered in January 2017 by the governments of Himachal Pradesh and Uttarakhand to directly monitor and manage construction logistics.
The 2026 Resource and Funding Framework
The newly brokered June 2026 agreement resolved complex fiscal and water-sharing mechanics through specific mandates:
- The 90:10 Funding Split: The Central Government will step in to fund 90% of the project's water component work as a national grant, leaving the six stakeholder states to fund only the remaining 10%.
- Unique Power-for-Water Swap: To eliminate standard cost-sharing friction, a strategic swap was introduced. Instead of Himachal Pradesh financing its share of the power segment, its allocated water capacity will be systematically supplied to fulfill the intense demands of Delhi and Rajasthan.
Rejuvenation of the Yamuna River
- Lean Season Flow Augmentation: By storing heavy monsoon torrents, the dam can systematically release controlled water volumes into the upper Yamuna basin. This will massively increase fresh environmental flows during dry summer months, aiding downstream ecological recovery.
Mitigating Regional Water Scarcity
- The Six Beneficiary States: The direct multi-state beneficiaries signing the agreement include Himachal Pradesh, Uttarakhand, Delhi, Uttar Pradesh, Haryana, and Rajasthan.
- Lifeline for the National Capital: The storage mechanism will act as a major long-term solution to permanently ease Delhi's recurring seasonal raw water shortages.
- Massive Agricultural Expansion: The network provides a reliable irrigation release system capable of watering over 97,000 hectares of parched agricultural fields across the beneficiary states.
