Six States sign the Kishau dam pact on the Tons; Centre to bear about 90% of the cost
A dam pending for about four decades finally has six signatures. Who gains, who loses land, and who pays?
Published 16 September 2026. Written by Pratidin from the reports linked at the end; every fact checked by a separate review before publishing. How we work
On 15 September 2026 the Chief Ministers of Uttar Pradesh, Uttarakhand, Himachal Pradesh, Rajasthan, Delhi and Haryana signed the agreement for the Kishau Multipurpose Project in New Delhi, in the presence of Union Home Minister Amit Shah and Union Jal Shakti Minister C.R. Patil. According to the Home Ministry's release, the project will build a 232.6-metre concrete gravity dam on the Tons, a tributary of the Yamuna, on the border of Himachal Pradesh and Uttarakhand. It will store 1,562 million cubic metres of water, irrigate about 97,000 hectares and generate 1,476 million units of hydroelectricity. The project has been declared a National Project, and the Government of India will bear about 90% of the financial burden, with the partner States sharing the rest.
The deal was prepared at a meeting chaired by Mr. Shah on 16 June 2026, where the six States agreed to sign an MoU. The Home Ministry said then that the Centre would give 90% assistance for the water component and the six States would share the remaining 10%; in lieu of sharing the cost of the power component, the water allocated to Himachal Pradesh would be supplied to Delhi and Rajasthan. It added that the project would go to the Union Cabinet for approval after the MoU. The legal root is a 12 May 1994 agreement among the Upper Yamuna basin States, which said each storage project would need its own agreement. Kishau's work moved ahead after the Lakhwar (August 2018) and Renukaji (2019) disputes were settled.
Mr. Shah called Kishau the tenth water dispute resolved since 2018, said the project had been pending for four decades, and said Delhi would be the biggest gainer and that the project would benefit both Delhi and the Yamuna. News reports put the cost at about ₹15,000 crore, the installed capacity at 422 MW and the submergence at about 2,950 hectares, and said Himachal Pradesh's concerns over cost sharing and land loss had delayed consensus. Supporters see upstream storage as the way to add lean-season flow to a stressed river. The concerns are the ones that follow every large Himalayan dam: displacement and rehabilitation, seismic and safety risk, and whether costs will keep rising before construction begins.

Recurring theme: Water storage, inter-State river projects and cooperative federalism
- How to use this
Kishau shows how upstream storage can add lean-season flow and irrigation across several States, giving a concrete storage example with figures.
- The Kishau Multipurpose Project, a 232.6-metre concrete gravity dam on the Tons (a Yamuna tributary), will store 1,562 million cubic metres and irrigate about 97,000 hectares, per the Home Ministry.
- Supporters see such upstream storage as the way to add lean-season flow to a stressed river like the Yamuna; Delhi is described as the biggest gainer.
- Caution that storage brings costs: reported submergence of about 2,950 hectares, displacement, seismic risk and the need for ecological flows in the Yamuna.
- How to use this
The Kishau pact is a recent case of the Centre brokering an inter-State water deal through funding and trade-offs, illustrating cooperative federalism at work.
- On 15 September 2026 six States (UP, Uttarakhand, Himachal Pradesh, Rajasthan, Delhi, Haryana) signed the Kishau agreement after a Home Minister-chaired meeting on 16 June 2026 produced consensus.
- As a National Project, the Centre bears about 90% of the cost; in lieu of Himachal sharing the power component cost, its water share goes to Delhi and Rajasthan.
- Drawback it exposes: the 12 May 1994 Upper Yamuna agreement required a separate pact for each storage project, reopening cost sharing each time; Mr. Shah said Kishau had been pending four decades.
- How to use this
Kishau, a very tall dam in the seismic Himalaya upstream of Delhi, lets you argue that new storage must build in safety review from the start.
- Kishau will be a 232.6-metre concrete gravity dam on the Tons on the Himachal Pradesh-Uttarakhand border, a seismic Himalayan setting.
- Concerns flagged with the project include seismic and safety risk, displacement and rehabilitation, and cost escalation before construction begins.
- Way forward: independent safety review and transparent monitoring for Kishau under the Dam Safety Act framework.
Kishau sits in the Yamuna system; knowing its tributaries, such as the Tons, and its glacier sources helps with Prelims geography.
Mains practice question
Inter-State river projects in India are delayed more by disputes over costs and land than by engineering. Examine this statement with reference to the Kishau Multipurpose Project. (250 words)
Model answer
The Kishau Multipurpose Project, a 232.6-metre dam on the Tons, was signed by six States on 15 September 2026 after decades of delay. Its history shows that the binding constraint was political economy, not design.
Why the delay was about money and land
- Shares were settled early: the 12 May 1994 Upper Yamuna agreement fixed water shares but required a separate pact for each storage project, reopening costs each time.
- Uneven burden: host States lose land (reported submergence about 2,950 hectares), while downstream Delhi gains most.
- Cost sharing: reports say Himachal Pradesh's concerns over cost and land loss held up consensus.
- Sequencing: Kishau moved only after Lakhwar (2018) and Renukaji (2019) were settled.
How the deadlock was broken
- National Project status: the Centre bears about 90% of the financial burden.
- Trade-offs across components: Himachal's water share goes to Delhi and Rajasthan instead of it paying for the power component.
- Central convening: a Home Minister-chaired meeting on 16 June 2026 produced consensus, reflecting cooperative federalism.
Remaining challenges
- Union Cabinet approval, cost escalation and timely construction.
- Rehabilitation of displaced families.
- Dam safety in a seismic Himalayan setting under the Dam Safety Act framework.
- Ecological flows in the Yamuna.
Way forward
- Time-bound rehabilitation packages agreed with host communities.
- Transparent project monitoring and independent safety review.
- A standing basin-level mechanism so each new project does not restart negotiations.
Kishau shows that when the Centre underwrites costs and brokers trade-offs, even a four-decade dispute can be settled; delivery will test whether that model holds.
The basics
Why this matters
Water in north India is shared across State borders, and big storage dams need every State that gains or loses to agree. The Kishau pact, signed on 15 September 2026, shows how that bargain is struck: who hosts the dam, who gets the water, and who pays.
What a multipurpose project does
A multipurpose project stores monsoon water and releases it over the year for irrigation, drinking water and hydropower, and, on the Yamuna, more flow in the dry months.

- 2UttarakhandCo-host State on the other bank of the Tons
- 3DelhiLargest gainer, according to the Home Minister
- 4Haryana, Uttar Pradesh, RajasthanBasin States that share water under the 1994 arrangement
- 5Union governmentDeclared it a National Project; bears about 90% of the financial burden
The legal root: one agreement, many dams
On 12 May 1994 the Upper Yamuna basin States reached an agreement on sharing the river's water. It said that separate agreements would be made for each storage project in the basin. That is why Lakhwar and Renukaji: the sister storage projects each needed their own pacts before Kishau could move. Read more in Upper Yamuna Agreement of 1994.
- 12 May 1994Basin States agree on sharing Upper Yamuna water; each storage project to get its own agreement
- August 2018Agreement on the Lakhwar project
- 2019Renukaji dispute settled; Kishau work moves ahead
- 16 June 2026Six States reach consensus at a meeting chaired by the Home Minister
- 15 September 2026Six Chief Ministers sign the Kishau agreement in New Delhi
Who pays for what
The money splits by purpose. Under the National Projects and the 90:10 funding pattern, the Centre carries most of the cost of the water component. In June the Home Ministry said the Centre would give 90% assistance for the water component and the six States would share the remaining 10%. In place of paying towards the power component, the water allocated to Himachal Pradesh would be supplied to Delhi and Rajasthan.
- Centre gives 90% assistance
- Six States share the remaining 10%
- About 97,000 hectares to be irrigated
- 1,476 million units of hydroelectricity a year expected
- Himachal's water share goes to Delhi and Rajasthan instead of cost sharing
- Reported installed capacity of 422 MW
The trade-offs
Upstream storage can add lean-season flow for Delhi and the Yamuna. The costs fall on the hills: reports put submergence at about 2,950 hectares. Safety matters too, since Concrete gravity dams in the Himalaya sit in seismically active terrain.
Go deeper
In one line: Six States signed the Kishau agreement on 15 September 2026 to build a 232.6-metre dam on the Tons, with the Centre bearing about 90% of the cost.
Why it matters for UPSC
It links GS2 federalism (inter-State water agreements, the Centre as broker) with GS3 irrigation, storage and hydropower, and with Prelims geography of the Yamuna basin.
The core idea
The Yamuna's upper basin is shared by several States. The Upper Yamuna Agreement of 1994 fixed how its water is divided and said each storage dam needs its own agreement. After deals on Lakhwar and Renukaji: the sister storage projects, Kishau was the last big hurdle. The Centre made it attractive through National Projects and the 90:10 funding pattern, and the dam itself will be one of the Concrete gravity dams that hold water back by sheer weight.
Numbers and dates to remember

- 232.6 m concrete gravity dam on the Tons, on the Himachal Pradesh-Uttarakhand border
- 1,562 million cubic metres of storage; about 97,000 hectares irrigated; 1,476 million units of power
- About 90% of the financial burden on the Centre; the project is a National Project
- 12 May 1994: Upper Yamuna water-sharing agreement
- Home Minister called it the tenth water dispute resolved since 2018

Go deeper: is the 90:10 model the right way to settle river disputes?
The case for the Kishau model. Inter-State river projects stall because the host State bears the land loss while downstream States get the water. Central money changes that calculation. By declaring Kishau a National Project and taking on about 90% of the burden, the Centre lowered the cost for every State at the table. The Home Minister described the approach as "solution through dialogue" and counted Kishau as the tenth water dispute resolved since 2018, following Lakhwar and Renukaji: the sister storage projects. The Upper Yamuna Agreement of 1994 had already settled shares, so the fight was over money and land, which are easier to trade than water rights.
The case for caution. A signed MoU is not a dam. In June the Home Ministry said the project would go to the Union Cabinet after the MoU. Costs grow with delay, and Kishau has been pending for about four decades by the Home Minister's own account. The burden also falls unevenly: reports put the submergence at about 2,950 hectares in the hills, while the largest gain goes to Delhi. Large reservoirs in young, seismically active mountains raise questions about Concrete gravity dams and their long-term safety, sediment and river ecology.
What to watch. Whether the National Projects and the 90:10 funding pattern is applied to the whole project or only to the water component matters for State budgets: the June statement spoke of the water component, while the September release spoke of about 90% of the overall financial burden. Rehabilitation of displaced families and dam safety supervision will decide whether the pact becomes a model or a warning.
Upper Yamuna Agreement of 1994
the rulebook that made a separate Kishau pact necessary
In one line: A 12 May 1994 agreement among the Upper Yamuna basin States divides the river's water and requires a separate agreement for each storage project.
What it is
Before big dams can be built on a shared river, States must agree on who gets how much water. For the upper Yamuna, the basin States signed such an agreement on 12 May 1994. The allocation it made has been reported as 11.983 billion cubic metres of utilisable surface water shared among the basin States.
Why it matters now
The Home Ministry's release on Kishau notes that the 1994 agreement said separate agreements would be made for each storage project in the basin. So even with water shares fixed, each dam needed a fresh deal on costs, benefits and power. Kishau is the latest of these.
Where to go next
National Projects and the 90:10 funding pattern
why the Centre pays most of the bill
In one line: A National Project is a water project the Centre funds heavily, usually about 90% of the cost of its irrigation and water component.
What it is
Some water projects are too large or too inter-State for any one State to finance. The Union government can declare such a project a National Project and bear most of the cost. For Lakhwar, notified as a National Project in 2008, the Union was to bear 90% of the cost.
How it works at Kishau
The Home Ministry release says Kishau has been declared a National Project and the Government of India will bear about 90% of the financial burden. In June 2026 the Ministry said the Centre would give 90% assistance for the water component, with the six States sharing 10%, and Himachal Pradesh's water share would go to Delhi and Rajasthan in lieu of sharing the power component cost.
Where to go next
Concrete gravity dams
what kind of structure is being built
In one line: A concrete gravity dam resists the push of the water behind it mainly through its own weight.
How it works
Water pushes sideways against a dam. A gravity dam is built so heavy and so wide at the base that this push cannot slide or tip it over. That is why gravity dams look like a triangle in cross-section, thick at the bottom and narrow at the top. They suit sites with strong rock foundations.
Why it matters for Kishau
Kishau is planned as a 232.6-metre concrete gravity dam. A structure of that size in the Himalaya needs careful safety design, monitoring and emergency plans, the kind of oversight the National Dam Safety Authority now reviews with States under the Dam Safety Act.
Where to go next
Lakhwar and Renukaji: the sister storage projects
the two deals that came before Kishau
In one line: Lakhwar in Uttarakhand and Renukaji in Himachal Pradesh are the two other Upper Yamuna storage projects whose agreements came before Kishau.
Lakhwar
The Lakhwar project is on the Yamuna in Uttarakhand, with a planned height of 204 metres. It was notified as a National Project in 2008, and its inter-State agreement was reached in August 2018. The Home Minister listed it among the water disputes resolved since 2018.
Renukaji
The Renukaji project in Himachal Pradesh was settled in 2019. The Home Ministry's release says Kishau's work moved ahead after the Lakhwar and Renukaji disputes ended. Together the three dams form the storage plan meant to hold monsoon water in the upper basin and release it through the dry season.
