The Rajasthan High Court directed the state government to submit a detailed response on its conservation plans for Gadisar Lake in Jaisalmer, as highlighted in November 2025. Gadisar Lake is a 14th-century artificial water reservoir built originally by Raja Rawal Jaisal and later renovated by Maharawal Gadsi Singh, from whom it gets its present name. The lake served as the primary drinking water source for the desert city of Jaisalmer for centuries and is a significant historical and ecological heritage site. The lake's catchment area has shrunk dramatically due to encroachment, urban pressure, siltation, and pollution, threatening its ecological balance. The lake supports migratory birds during winter and functions as an important urban-wetland ecosystem in the Thar Desert. The High Court's intervention follows persistent civil society concerns over unregulated construction near the lake's catchment zone and lack of desilting activities. Gadisar Lake is also listed as a heritage site under the Archaeological Survey of India (ASI) and is one of Jaisalmer's most visited tourist destinations. The case highlights the broader challenge of balancing urban development with conservation of Rajasthan's traditional water harvesting infrastructure — including baolis, kunds, johads, and nadis — which are integral to the region's arid-zone water management heritage.
