Around November 2025, the Rajasthan High Court directed the state government to submit a detailed response and action plan on conserving the Gadisar Lake in Jaisalmer — a 14th-century artificial water reservoir that is both a heritage monument and an ecological asset. Gadisar Lake was originally built by Raja Rawal Jaisal (founder of Jaisalmer) and later renovated by Maharawal Gadsi Singh (after whom it is named). Historically, it served as the primary source of water for the city of Jaisalmer and remains a critical example of indigenous water conservation engineering in the Thar Desert region. The lake's catchment area has significantly shrunk due to urban encroachment, siltation, and pollution. It supports migratory bird populations — including flamingos, pelicans, and various wetland species — during winter months, giving it ecological significance as an urban wetland. The High Court's intervention comes at a time when Rajasthan's desert water bodies — including Pushkar Lake, Anasagar Lake (Ajmer), and Nakki Lake (Mount Abu) — are under similar stress. Rajasthan's traditional water management systems (johads, baolis, bawdis, and step-wells) represent a rich legacy that the state government has been urged to revive under the Mukhyamantri Jal Swavalamban Abhiyan. The case reflects growing judicial activism in environmental governance in Rajasthan.
