Kalpasar Project: Gujarat’s 60‑km Gulf Dam to End Droughts – Indo‑Dutch Collaboration
The Kalpasar Project proposes a 60 km dam across Gujarat’s Gulf of Khambhat to create a 7,800 MCM freshwater reservoir, irrigate over 10 lakh hectares, and generate renewable energy. Backed by Indo‑Dutch technical cooperation, the scheme aims to end chronic droughts in Saurashtra while boosting agriculture, fisheries, and transport infrastructure.
Overview The state of Gulf of Khambhat has been a chronic water‑scarcity zone. Gujarat has recorded almost 30 droughts since 1900, affecting Saurashtra, Kutch and North Gujarat every three years. The Kalpasar Project aims to end this cycle by building a massive freshwater reservoir and associated infrastructure. Key Developments Prime Minister Narendra Modi visited the Dutch Afsluitdijk in 2025 and signed a Letter of Intent for technical cooperation on Kalpasar. The pre‑feasibility report (2022) details a 60.13 km dam, 7,800 MCM storage, and irrigation of 10.54 lakh hectares. Four major rivers (Sabarmati, Mahi, Dhadhar, Narmada) and seven minor rivers will feed the reservoir via a diversion canal at Bhadbhut barrage. Renewable energy potential of 1,000 MW solar + 1,500 MW wind is earmarked to power the project. A 16‑lane road and 4‑lane rail link will cut travel across the Gulf from 240 km to 60 km. Important Facts Dam length: 60.13 km (26.7 km in sea, 33.43 km on flanks). Storage capacity: 7,800 million cubic metres (MCM), one of the world’s largest. Irrigation coverage: 10.54 lakh hectares across nine Saurashtra districts. Land reclamation: ~1.76 lakh hectares for agriculture and settlement. Fisheries shift: Freshwater fish production projected to rise from 2,000 to 20,000 tonnes. Tidal range: Approximately 13 metres , providing natural head for the dam. UPSC Relevance The project illustrates the intersection of water security , climate adaptation and infrastructure development —key themes in GS‑3 (Environment, Water Resources) and GS‑2 (Polity) when discussing inter‑governmental cooperation. It also showcases the role of international technical collaboration (India‑Netherlands) in large‑scale projects, a recurring topic in questions on foreign policy and technology transfer. Way Forward Implementation hinges on completing detailed feasibility studies, securing environmental clearances, and finalising the Indo‑Dutch technical partnership. Major challenges include land acquisition, ecological impacts on coastal mangroves, and financing of the multi‑billion‑dollar scheme. If addressed, Kalpasar could become a model for integrated water‑resource management, renewable‑energy integration, and regional connectivity in India.

Background
Gujarat faces chronic droughts; over 30 drought events since 1900 have hit Saurashtra, Kutch and North Gujarat. Kalpasar seeks to capture monsoon runoff, transfer water across basins and create a large freshwater reservoir, linking water security with climate adaptation, infrastructure and international technology transfer – core themes of GS‑3 and GS‑2.
