River Interlinking in India: Ken-Betwa Link and the National Perspective Plan
The decades-old idea of linking India's rivers to move water from “surplus” to “deficit” basins has, for the first time, moved off paper and into construction with the Ken-Betwa Link — making the Interlinking of Rivers (ILR) programme, its governance architecture, and its environmental trade-offs a high-value, frequently tested theme across GS Paper 1 (Geography) and GS Paper 3 (water security, environment).
📌 Revision Pointers
NPP basics — National Perspective Plan (1980): Himalayan component (14 links) + Peninsular component (16 links) = 30 links; NWDA (1982, Ministry of Jal Shakti) prepares FRs/DPRs.
Ken-Betwa specifics — transfers water from Ken (MP) to Betwa (MP-UP) via Daudhan Dam; passes through Panna Tiger Reserve; cost ~Rs 44,605 crore.
Status marker — the ONLY priority link among 30 to have entered the implementation stage (foundation stone laid December 2024).
Progress numbers — Feasibility Reports complete for 26 links, DPRs complete for 13 links (as of 2026); Damanganga-Pinjal and Par-Tapi-Narmada dropped from priority status.
Key criticism — the “surplus/deficit” basin classification itself is scientifically disputed; add ecological submergence, displacement, and inter-state water disputes as recurring criticism threads.
PYQ Connect — Interlinking of rivers has been tested directly in GS Mains (feasibility and implications of river interlinking) and feeds GS Paper 1 drainage-system questions and GS Paper 3 water security/disaster management questions; also link to Environment themes via Panna Tiger Reserve and EIA.
Core Concept
The Interlinking of Rivers (ILR) programme is a National Perspective Plan (NPP), prepared in 1980, that proposes transferring water from river basins perceived to have a surplus to basins facing a deficit, through a network of canals and reservoirs. It has two components — the Himalayan Rivers Development Component (14 links) and the Peninsular Rivers Development Component (16 links) — totalling 30 identified links, studied and implemented by the National Water Development Agency (NWDA, set up in 1982) under the Ministry of Jal Shakti.
Key Points
Two components, 30 links — Himalayan component (14 links, involving the Ganga-Brahmaputra system and transboundary rivers) and Peninsular component (16 links, mostly intra-India, such as Godavari-Krishna and Ken-Betwa).
Ken-Betwa Link Project — the first and, so far, the only ILR project to enter the implementation stage; it transfers surplus water from the Ken river (Madhya Pradesh) to the water-deficit Betwa basin (Madhya Pradesh and Uttar Pradesh) via the proposed Daudhan Dam, and passes through the core area of the Panna Tiger Reserve.
Institutional architecture — the Special Committee for Interlinking of Rivers monitors overall progress, a dedicated Task Force oversaw the Ken-Betwa project's fast-tracking, and NWDA prepares the Feasibility Reports (FRs) and Detailed Project Reports (DPRs) for each link.
Progress across the 30 links — Feasibility Reports are complete for 26 links and DPRs for 13; some proposed links (Damanganga-Pinjal, Par-Tapi-Narmada) have been dropped from priority status, and the Kosi-Mechi inter-state link was shelved after raising cross-border complications.
Core criticisms — the very idea of a river basin having a permanent “surplus” is scientifically contested; concerns also include submergence of tiger habitat and displacement in Ken-Betwa, inter-state water-sharing disputes, high and rising project costs, and the ecological cost of large dam-and-canal networks.
Memory Trick
Remember the scale as “14 + 16 = 30” (Himalayan + Peninsular = total links). For direction, think “Ken gives, Betwa gets” — water moves from the Ken (surplus) to the Betwa (deficit). For status, remember “Only one link has left the launchpad” — of all 30 identified links, Ken-Betwa alone has moved from paper (DPR) to actual construction.
Current Relevance (2024-2026)
The Prime Minister laid the foundation stone for the Ken-Betwa Link National Project in December 2024, formally starting construction on India's first inter-basin water transfer under the ILR programme. Through 2025-2026, the project has remained under active implementation: a Comprehensive Environmental Impact Assessment and an Integrated Landscape Management Plan for the affected stretch of the Panna Tiger Reserve have been completed, and the government's estimate (Rajya Sabha reply, 10 August 2026) puts the project cost at Rs 44,605 crore (including Rs 39,317 crore of central support), expected to irrigate about 11.88 lakh hectares, supply drinking water to roughly 62 lakh people, and generate 103 MW of hydropower plus 27 MW of solar power. The same reply confirmed Ken-Betwa is still the only one of the 30 identified NPP links to have entered implementation, while Feasibility Reports now stand complete for 26 links and DPRs for 13 — keeping the broader interlinking debate (feasibility, ecology, federal water disputes) current for 2026 exams.
💭 Conclusion
With Ken-Betwa now the one live proof-of-concept for India's five-decade-old river-linking idea, expect this theme to keep recurring — both as a factual question on the NPP's structure and progress, and as an analytical one on whether inter-basin transfer is an ecologically sound answer to water scarcity.
