Introduction: Ken-Betwa — India’s First River Interlinking Project
The Ken-Betwa River Interlinking Project is India’s first inter-basin water transfer project under the ambitious National Perspective Plan for interlinking rivers. It has been in planning for over two decades and finally received Cabinet Committee on Economic Affairs (CCEA) approval in December 2021. For UPSC aspirants, this project is a gold mine — it spans GS2 (interstate relations, Article 262), GS3 (water conservation, environment, wildlife) and Prelims geography. This post provides a comprehensive analysis.
Project Overview: Geography and Objectives
The Ken-Betwa Link Project connects the Ken River in Madhya Pradesh to the Betwa River in Uttar Pradesh — both tributaries of the Yamuna. The project aims to transfer surplus water from the Ken basin (which has more water relative to irrigation demand) to the water-deficit Betwa basin in the drought-prone Bundelkhand region.
The project has two phases:
- Phase 1: Construction of Daudhan Dam on the Ken River (height 77 metres, capacity 2853.01 MCM), a Low Level Tunnel, a High Level Canal, and a Powerhouse. Water from Ken will be transferred to Betwa via a 221 km canal network.
- Phase 2: Construction of Lower Orr Dam, Bina Complex Project, and Kotha Barrage.
Key Benefits: Why India Needs This Project
The Bundelkhand region spanning parts of Madhya Pradesh and Uttar Pradesh is chronically water-deficient, leading to farmer distress, migration, and recurring drought. The project promises:
- Irrigation: 10.62 lakh hectares of agricultural land (6.35 lakh ha in UP, 2.51 lakh ha in MP) will receive assured irrigation.
- Drinking water: Approximately 44 lakh people across 13 districts of UP and MP will get drinking water.
- Power generation: 103 MW hydropower from the dam and solar power installations.
- Flood mitigation: Regulated flow will reduce downstream flooding.
Institutional Framework: NWDA’s Role
The National Water Development Agency (NWDA), functioning under the Ministry of Jal Shakti, is the nodal agency for India’s river interlinking programme. NWDA prepared the DPR (Detailed Project Report) for Ken-Betwa over multiple decades. The project is now implemented by the Ken-Betwa Link Project Authority (KBLPA) set up in 2022 under the Union Government.
The National Perspective Plan proposes 30 river interlinking projects — 14 under the Himalayan component and 16 under the Peninsular component (including Ken-Betwa).
Environmental and Wildlife Controversy: Panna Tiger Reserve
The most contentious issue with the Ken-Betwa project is the Daudhan Dam’s submergence of 9,000 hectares of Panna Tiger Reserve’s core area — India’s 22nd tiger reserve and a critical wildlife corridor.
Wildlife at Risk:
- Gharial (Gavialis gangeticus): Critically endangered crocodilian species, one of the most threatened in the world. The Ken river hosts one of India’s last viable gharial populations (~70 adults). The dam will drastically reduce their habitat.
- Bengal Tigers: Panna Tiger Reserve was famously saved from local extinction through translocations in 2009-2012. Post-recovery, it now has ~70 tigers. Submergence disrupts tiger corridors.
- Ken River Dolphins (Gangetic dolphins): Scheduled species found in the Ken river will lose critical habitat.
- Vultures and raptors: Dense forest area in the submergence zone supports nesting habitats.
Approvals Obtained:
- Wildlife Board clearance granted — controversial, as it required overriding wildlife concerns for development
- Forest clearance under Forest Conservation Act obtained
- Supreme Court-monitored Central Empowered Committee (CEC) objections were overruled by the apex court
- NGT hearings raised questions about Environmental Impact Assessment (EIA) adequacy
Legal Framework: Article 262 and Interstate Water Disputes
India’s constitutional provisions for interstate water disputes include:
- Article 262: Parliament can by law provide for adjudication of disputes relating to waters of inter-state rivers. No court (including Supreme Court) can exercise jurisdiction in matters referred to a tribunal under such law.
- Inter-State River Water Disputes Act, 1956: Enacted under Article 262, this Act provides for the constitution of Water Dispute Tribunals. Under this Act, the Central Government can establish a tribunal when disputes cannot be resolved through negotiation.
- Ken-Betwa Agreement (2021): Both MP and UP signed a bilateral MoU on water sharing — 2,316 MCM to UP and 1,073 MCM to MP from the link canal annually.

UPSC Prelims High-Probability Points
- Ken-Betwa is India’s first river interlinking project under implementation
- NWDA is under Ministry of Jal Shakti
- Daudhan Dam height: 77 metres
- Gharial is Schedule 1 species under Wildlife Protection Act 1972
- Article 262 governs inter-state water disputes
- CCEA approval: December 2021
- Cost: approximately Rs. 44,000 crore (revised)
GS Mains Perspective: Environment vs Development Debate
The Ken-Betwa project perfectly illustrates India’s classic dilemma — development vs. ecology. UPSC Mains questions on “Should development needs override environmental concerns?” can be answered using this case study. Key arguments:
For the project: Bundelkhand’s chronic drought, farmer suicides, and migration demand urgent action. Water security is a constitutional right under Article 21 (Right to Life). 44 lakh people and 10+ lakh hectares of agricultural land justify the project.
Against the project: Gharial near extinction, tiger corridor disruption, and inadequate EIA. Alternatives like check dams, rainwater harvesting, and aquifer recharge in Bundelkhand were not adequately explored before approving the mega-project.

Frequently Asked Questions (FAQs)
1. Why is Ken-Betwa considered India’s first river interlinking project?
While the idea of interlinking rivers in India dates back to the 1970s (K.L. Rao’s proposal) and the National Water Development Agency prepared DPRs for 30 interlinking proposals since the 1980s, the Ken-Betwa Link Project (KBLP) is the first to receive Cabinet approval (December 2021), bilateral state agreement, and begin actual construction. All other proposed projects are still in the planning or DPR stage, making Ken-Betwa uniquely advanced and thus termed India’s first river interlinking project.
2. How does the submergence of Panna Tiger Reserve threaten gharials?
The Gharial (Gavialis gangeticus) is critically endangered with fewer than 300 mature individuals globally. The Ken River is one of the last rivers with a breeding gharial population (~70 adults). The Daudhan Dam will submerge approximately 10 km of prime gharial nesting habitat — sandy riverbanks used for egg-laying. Additionally, the transformation of a free-flowing river into a reservoir alters water temperature, flow velocity, and fish populations that gharials depend on for food. Biologists argue this could effectively eliminate the Ken River gharial population.
3. What is Article 262 and how does it apply to the Ken-Betwa project?
Article 262 of the Indian Constitution empowers Parliament to legislate on inter-state river water disputes and explicitly bars the Supreme Court from exercising jurisdiction in disputes adjudicated by a tribunal constituted under such legislation. The Inter-State River Water Disputes Act 1956 was enacted under Article 262. However, the Ken-Betwa project did not require a tribunal because both Madhya Pradesh and Uttar Pradesh signed a voluntary MoU on water sharing in March 2021 — 2,316 MCM allocated to UP and 1,073 MCM to MP annually from the link canal.
4. What is the Peninsular Rivers Development component of the National Perspective Plan?
The National Perspective Plan (NPP) for interlinking of rivers has two components. The Himalayan Rivers Development component involves storage reservoirs on Himalayan rivers (Ganga, Brahmaputra) to enable transfers northward. The Peninsular Rivers Development component — under which Ken-Betwa falls — involves interlinking rivers of the Deccan plateau, primarily the Krishna, Godavari, Cauvery, and Mahanadi systems, to transfer water from water-surplus eastern rivers to water-deficit western and southern regions. NWDA has prepared DPRs for 16 Peninsular component links, of which Ken-Betwa is the first to proceed.
