Sukhna Lake, the life line of the union territory of Chandigarh, has been shrinking at a rapid pace. The lake lies in the foothills of Siwalik Hills in the outer Himalayas. It is an artificial and rain fed lake created by damming the Sukhna Choe, a seasonal stream coming down from the Shiwalik hills. It also serves as an outlet for Sukhna watershed of about 52 km2 and is mainly fed by two seasonal tributaries namely Kansal and Suketri (Ghareri and Nepli tributaries). The area of the lake is 3 km2 and it lies between latitudes 30Â° 44â€™ and 30Â° 50â€™ N and longitudes 76Â°48â€™ to 76Â° 54â€™ E. This study deals with the in-depth review of the conditions of the Sukhna Lake with respect to water quality, weed status and morphological characteristics using GIS and remote sensing techniques. The use of GIS and remote sensing techniques present a perspective view of the conditions of lake which is necessary for strategic decision making regarding the conservation of the lake and sustainability of lake restoration efforts.
