The Rajasthan High Court, on or around November 18, 2025, directed the state government to submit a detailed action plan for the conservation of Gadisar Lake in Jaisalmer — a 14th-century artificial water reservoir built by Raja Rawal Jaisal and later renovated by Maharawal Gadsi Singh (from whom it derives its name). The lake had historically served as the primary water source for the entire Jaisalmer city and functioned as a critical rainwater harvesting system in the Thar Desert. The court's intervention came amid concerns about encroachment, deteriorating water quality, and pollution of the lake's catchment area. Gadisar Lake is an engineering marvel of medieval Rajasthan, featuring ghats, temples, and chattris, and has been recognised as a heritage site. The lake exemplifies Rajasthan's traditional water conservation wisdom — alongside kunds, baolis, johads, and tankas — that sustained life in the arid zone for centuries. This case is significant in the context of India's National Water Policy and judicial activism in protecting water bodies under the public trust doctrine.
