Sukhna Lake: a man-made, rain-fed reservoir made by damming a Shivalik stream
Background
Sukhna Lake, "nestled at the foothills of the Shivalik Hills in Chandigarh, India, is one of the most beautiful man-made lakes in India". The Ministry of Tourism describes it as "A declared National Wetland, this 3 square kilometre rain-fed reservoir" that "came into existence in 1958 when the Sukhna Choe, a seasonal stream originating from the Shivalik Hills, was dammed". "Architect Le Corbusier, along with Chief Engineer L. Verma, envisioned Sukhna Lake as a serene oasis." Two rules were set to protect it: "motorboats are forbidden on the water, and vehicular traffic is prohibited on the dam's promenade". The roof of the dam serves as the lake's promenade. In winter the lake "becomes a sanctuary for exotic migratory birds such as the Siberian duck, storks, and cranes". It has hosted the Asian Rowing Championships and "boasts Asia's longest channel for rowing and yachting events".
