Kalpasar Project: Gujarat’s 60‑km Gulf Dam to End Century‑Long Droughts – Indo‑Dutch Collaboration

Overview Gujarat, a drought‑prone state that has faced water scarcity about 30 times since 1900 , is moving ahead with the Kalpasar Project . The scheme proposes a 60.13 km dam across the Gulf of Khambhat , creating one of the world’s largest freshwater reservoirs. Key Developments Prime Minister Narendra Modi visited the Dutch Afsluitdijk in 2025 and signed a Letter of Intent for technical cooperation. The project has been on Gujarat’s agenda since 1986 ; feasibility studies were approved in 2003 and a Pre‑Feasibility Report was released in 2022 . Four major rivers – Sabarmati, Mahi, Dhadhar and Narmada – along with seven minor rivers will feed the reservoir via a diversion canal at the Bhadbhut barrage. Renewable‑energy potential includes 1,000 MW solar and 1,500 MW wind installations. A 16‑lane road and a 4‑lane rail link will cut travel across the Gulf from 240 km to 60 km . Important Facts The dam will have a sea‑portion of 26.7 km and land‑portion of 33.43 km . The resulting freshwater reservoir will hold 7,800 million cubic metres (MCM) , enough to irrigate 10.54 lakh hectares across nine districts of Saurashtra. It will also replenish over 60 existing dams and reclaim 1.76 lakh hectares of land. Environmental benefits include groundwater recharge, reduction of coastal salinity, and a shift from marine to freshwater fisheries, raising annual fish production from 2,000 tonnes to 20,000 tonnes . The project’s renewable‑energy component can meet its own power demand and contribute to Gujarat’s clean‑energy goals. UPSC Relevance Understanding the Kalpasar Project helps aspirants link geography, economics and governance. The case illustrates: How physical geography ( tidal range of ~13 m) influences engineering decisions. Inter‑state cooperation (India‑Netherlands) as a model for technology transfer in water management. Policy challenges such as environmental clearances, displacement, and financing of mega‑infrastructure. Implications for agriculture, energy transition, and regional development – core topics in GS3. Way Forward To accelerate implementation, the government must: Finalize detailed project reports and secure multi‑year financing, possibly through public‑private partnerships. Complete environmental impact assessments, ensuring mitigation for affected communities and ecosystems. Leverage Dutch expertise for dam design, flood‑regulation and coastal protection, while building domestic technical capacity. Integrate the project with Gujarat’s broader water‑security strategy, including rain‑water harvesting and groundwater management. Successful execution will not only end Gujarat’s chronic drought cycle but also set a benchmark for large‑scale water‑resource projects in India.
