Sukhna Lake in Chandigarh, India, is a reservoir at the foothills (Shivalik hills) of the Himalayas. This 3 km² rainfed lake was created in 1958 by damming the Sukhna Choe, a seasonal stream coming down from the Shivalik Hills. Originally the seasonal flow entered the lake directly causing heavy siltation. To check the inflow of silt, 25.42 km² of land was acquired in the catchment area and put under vegetation. In 1974, the Choe was diverted and made to bypass the lake completely, the lake being fed by three siltation pots, minimising the entry of silt into the lake itself.HistoryThe lake was created by Le Corbusier and the Chief Engineer P L Verma. To preserve its tranquility, Corbusier insisted on two things: that it be forbidden for motor boats to circulate in the water, and for vehicular traffic to be prohibited on top of the dam (promenade). The lake is fringed by a golf course to the south, and Nek Chand's famous Rock Garden of Chandigarh to its west.Local loreSukhna is an inseparable part of the city of Chandigarh. Le Corbusier had foreseen that the residents of the city would be drawn it for the 'care of the body and spirit'. The city planners were deeply attached to the lake. So much so that Pierre Jeanneret's ashes were immersed in the lake in 1970 at his niece's request.
