What Is the Kishau Multipurpose Project and Why Is It Important for Northern States?

The Kishau Multipurpose Project is a major national hydraulic engineering venture planned on the Tons River, straddling the border between the Sirmaur district of Himachal Pradesh and the Dehradun district of Uttarakhand. The Tons River constitutes the largest hydrological tributary of the Yamuna River system, originating in the Garhwal Himalayas near the Bandarpoonch mountain massif and carrying greater discharge volume than the main Yamuna stream at their confluence near Kalsi and Dakpathar. Conceptualized to regulate the volatile monsoon discharges of the upper Yamuna catchment, the project features a massive 236-metre-high concrete gravity dam designed to impound approximately 1,324 million cubic metres of gross reservoir storage, including a live storage volume of 0.24 million hectare-metres. By retaining surplus monsoon runoff, the reservoir addresses chronic water deficits across the northern agrarian plains and thirsty urban metropolitan clusters.

The interstate architecture of the Kishau project reflects complex federal water governance across six northern basin jurisdictions, namely Himachal Pradesh, Uttarakhand, Uttar Pradesh, Haryana, Rajasthan, and the National Capital Territory of Delhi. Formalized under the Upper Yamuna River Basin Memorandum of Understanding of May 1994, water allocations aim to stabilize irrigation supplies across 97,076 hectares of farmland while supplying 619 million cubic metres of dedicated drinking and municipal water to urban centres, most notably Delhi. The power generation infrastructure incorporates an underground powerhouse housing four Francis turbine units of 165 megawatts each, producing a total installed capacity of 660 megawatts. Recognising its regional significance, the Union Government designated Kishau a National Project in 2008, establishing a financing framework where the Centre provides a ninety percent grant for the water and irrigation component, leaving ten percent for beneficiary states, while the power component is shared equally between Himachal Pradesh and Uttarakhand.

Implementation of the venture is managed by Kishau Corporation Limited, an equal joint venture between the Himachal Pradesh Power Corporation Limited and Uttarakhand Jal Vidyut Nigam Limited. Beyond supplying peaking electrical energy and irrigation canals, the project fulfils a distinct function in ecological flow augmentation for the degraded downstream reaches of the Yamuna River during lean winter and pre-monsoon months. However, executing this colossal highland reservoir demands addressing significant geological, seismic, and rehabilitation challenges in the ecologically fragile Lesser Himalayas. Project authorities must balance structural safety in Seismic Zone IV with the compensatory resettlement of displaced hill communities under modern land acquisition laws, making Kishau a defining case study in inter-state water federalism and sustainable highland resource management.

The Kishau Multipurpose Project is located on the Tons River across the interstate border of Sirmaur district in Himachal Pradesh and Dehradun district in Uttarakhand.

The Tons River is the largest tributary of the Yamuna River, rising from the Bandarpoonch mountain range and carrying more water discharge than the main Yamuna before their confluence at Kalsi.

The project involves the construction of a 236-metre-high concrete gravity dam, making it one of the tallest concrete dams planned in the Indian Himalayas.

The dam creates an expansive reservoir with a gross storage capacity of approximately 1,324 million cubic metres and an effective live storage of 0.24 million hectare-metres.

The powerhouse has an installed capacity of 660 megawatts, comprising four underground Francis generating units of 165 megawatts each.

Electrical power generated from the 660 MW facility is divided equally on a 50:50 basis between the host states of Himachal Pradesh and Uttarakhand.

Water storage from Kishau is allocated among six northern states: Himachal Pradesh, Uttarakhand, Uttar Pradesh, Haryana, Rajasthan, and Delhi.

The project provides assured irrigation to 97,076 hectares of agricultural land spread across Haryana, Rajasthan, and Uttar Pradesh.

Kishau provides 619 million cubic metres of drinking and industrial water, significantly augmenting municipal supply for the National Capital Territory of Delhi.

#10

The Union Government declared Kishau a National Project in 2008 under the guidelines of the Ministry of Water Resources (now Ministry of Jal Shakti).

#11

Under the National Project funding formula, the Central Government provides 90 percent of the capital cost for the water and irrigation component as a central grant.

#12

The remaining 10 percent of the water component cost is shared among the beneficiary basin states in proportion to their water allocations.

#13

The capital expenditure for the power generation component is funded equally (50:50) by the governments of Himachal Pradesh and Uttarakhand.

#14

Project execution is entrusted to Kishau Corporation Limited, an incorporated joint venture between Himachal Pradesh Power Corporation Limited (HPPCL) and Uttarakhand Jal Vidyut Nigam Limited (UJVNL).

#15

The interstate water sharing framework derives from the Upper Yamuna River Basin Memorandum of Understanding signed by five state Chief Ministers on 12 May 1994.

#16

The Upper Yamuna River Board (UYRB), a subordinate office of the Ministry of Jal Shakti created in 1994, supervises water regulation and lean-season releases.

#17

Kishau is one of three recognized national storage reservoirs on the Yamuna basin, alongside the Renukaji Dam on the Giri River and the Lakhwar Dam on the Yamuna River.

#18

Regulated reservoir releases during non-monsoon months are engineered to maintain mandatory environmental flows to restore the ecological health of the downstream Yamuna.

#19

Environmental clearance mandates strict compliance with the Environment (Protection) Act of 1986 and compensatory afforestation under the CAMPA statutory framework.

#20

Land acquisition and resettlement of displaced families in both Sirmaur and Dehradun districts fall under the Right to Fair Compensation and Transparency in Land Acquisition, Rehabilitation and Resettlement Act of 2013.

Educator's Insight

Examiners frequently test the hydrological distinction between the Tons and Yamuna rivers. A standard trap in civil services tests asks candidates to identify the primary tributary of the Yamuna by volume; many mistakenly choose the Chambal, overlooking that the Tons carries almost twice the flow of the upper Yamuna at Dakpathar. Candidates should also note the distinct cost-sharing ratio: the water component receives a ninety percent central grant with ten percent state funding, whereas the power component requires an equal fifty-fifty split between Himachal Pradesh and Uttarakhand.

To master the three national storage projects designed to rejuvenate the Yamuna basin, memorize the mnemonic 'K-L-R' representing Kishau on the Tons River, Lakhwar on the main Yamuna River, and Renukaji on the Giri River. Keep in mind that Kishau and Lakhwar involve Uttarakhand, whereas Renukaji is situated entirely within Himachal Pradesh. Remembering this geographical distribution prevents errors in state-specific infrastructure questions.
