Ropar Wetland, also named Ropar Lake, is a man-made freshwater riverine and lacustrine wetland. The area has at least 9 mammal, 154 bird (migratory and local), 35 fish, 9 arthropod, 11 rotifer, 9 crustacean and 10 protozoan species, making it biologically diverse. This important ecological zone is located in the Shivalik foothills of the Lower Himalayas and was created in 1952 on the Sutlej River, in the Punjab state of India, by building a head regulator to store and divert water for beneficial uses of irrigation, drinking and industrial water supply. The endangered turtle Chitra indica and the threatened snake Python molurus ("at lower risk"), as per IUCN Redlist, are reported to be resident in the wetland.
