Quick Revision: The Kosi-Mechi Inter-State Link Project, funded under PMKSY-AIBP, aims to enhance irrigation and flood control in Bihar by diverting Kosi waters to the Mechi basin, with completion targeted by March 2029.
Why is this in the news?
The Kosi-Mechi Inter-State Link Project has been included under the Pradhan Mantri Krishi Sinchayee Yojana-Accelerated Irrigation Benefits Programme (PMKSY-AIBP) with a central assistance of ₹3,652.56 crore, indicating renewed focus on inter-state and cross-border water resource development. The project, scheduled for completion by March 2029, aims to enhance irrigation in Bihar while fostering bilateral cooperation with Nepal on the Kosi basin. The inclusion of the project in PMKSY-AIBP underscores the government’s commitment to accelerate irrigation infrastructure development in eastern India, a region prone to both floods and water scarcity.
Background
- The Kosi River, originating in Nepal, is a major tributary of the Ganga and is notorious for its high sediment load and frequent floods, causing extensive damage to life and property in Bihar.
- The Kosi-Mechi Inter-State Link Project is part of a broader initiative to harness the waters of the Kosi River for irrigation, flood control, and hydroelectric power generation in Bihar and adjoining states.
- The Kosi basin has been a focal point of bilateral discussions due to its potential for multi-purpose river valley development, including irrigation, flood mitigation, and navigation.
- The PMKSY-AIBP, launched in 2015, aims to enhance physical access to irrigation through minor and medium irrigation projects, with a focus on completing ongoing projects.
- Bihar has historically received significant central assistance for flood management, including ₹206.77 crore over the past three years under the Flood Management and Border Areas Programme.
What is the Kosi-Mechi Inter-State Link Project?
- The Kosi-Mechi Inter-State Link Project is an inter-state irrigation and flood control initiative aimed at diverting surplus waters from the Kosi River to the Mechi River basin in Bihar, thereby enhancing agricultural productivity in the region.
- The project is being implemented under the PMKSY-AIBP, with a total estimated cost of ₹6,143.22 crore, of which ₹3,652.56 crore is provided as central assistance.
- The project includes the reconstruction of the Eastern Kosi Main Canal, with a contract worth ₹2,639.80 crore awarded for a 41.30 km stretch, and 8.5% physical progress achieved to date.
- The project is expected to be completed by March 2029, aligning with the broader objectives of the PMKSY to enhance irrigation coverage and reduce water stress in eastern India.
- The project is part of a larger ecosystem of inter-state and cross-border water resource development initiatives, including the proposed Sapta-Kosi Multi-Purpose Project and Sun-Kosi-Kamala Diversion Multi-Purpose Project.
- The project underscores the importance of multi-disciplinary studies, including topographical surveys, hydrological assessments, seismic studies, and Glacial Lake Outburst Flood (GLOF) analyses, to ensure technical feasibility and disaster resilience.

Strategic
- Strengthens India-Nepal bilateral cooperation on transboundary river management, fostering regional stability and mutual trust.
- Enhances flood control mechanisms in the Kosi-Gandak basin, reducing the socio-economic impact of recurrent floods in Bihar and Nepal.
Environmental
- Integrates modern hydrological and seismic studies to ensure structural resilience against glacial lake outburst floods (GLOFs) and seismic activity.
- Promotes sustainable water resource management through inter-basin water transfer, balancing ecological needs with developmental priorities.
Institutional
- Leverages the PMKSY-AIBP framework to ensure convergence of central and state resources, accelerating project implementation.
- Facilitates capacity-building through joint technical studies and surveys, enhancing institutional expertise in river basin management.
Challenges
1. Geopolitical Coordination
- Requires sustained diplomatic engagement with Nepal to finalize agreements on dam construction and water-sharing protocols.
- Delays in bilateral consultations, as evidenced by no India-Nepal Joint Committee meetings in 2025-26, pose risks to project timelines.

Challenges — UPSC Perspective
| Issue | Concern |
|---|---|
| Bilateral Diplomacy | Delays in India-Nepal consultations may stall project implementation and water-sharing agreements. |
| Hydrological Modeling | Precise water balance calculations are required to prevent downstream water deficits in Nepal. |
| Seismic and GLOF Risks | Structural designs must account for high seismic activity and glacial lake outburst flood scenarios. |
