The Rajasthan High Court, around November 19, 2025, directed the state government to submit a detailed response and conservation plan for Gadisar Lake in Jaisalmer. Gadisar (also known as Gadsisar) is a 14th-century artificial water reservoir constructed by Maharawal Gadsi Singh to meet the water needs of his arid lands. It served as the primary water source for Jaisalmer town for centuries and is an architectural marvel surrounded by temples, cenotaphs (chhatris), and ghats. The lake's catchment area has shrunk sharply due to encroachment, urban pressure, siltation, and pollution from untreated sewage. It supports significant local biodiversity including migratory birds that visit in winter, making it an ecologically sensitive zone. The High Court's intervention follows petitions filed by environmental activists and local civil society groups. The case highlights the tension between rapid urbanisation and the protection of historic water bodies — a challenge across Rajasthan's many heritage lakes including Pushkar Lake, Ana Sagar, and Sambhar. Rajasthan has 562 notified water bodies, many of which face similar threats from encroachment and neglect.
