The Site is a marshy lake located within Therthangal village in southern Tamil Nadu. The wetland is fed by two rivers during the rainy season. Ninety-six bird species have been recorded in the Site, including the endangered Egyptian vulture (Neophron percnopterus) and the vulnerable Indian spotted eagle (Clanga hastata). The babul (Acacia nilotica) trees planted by the forest department provide popular nesting sites for migratory birds. In 2010, the Site was designated as a bird sanctuary. In addition to birds, the Site also supports 133 plant, 57 butterfly, 11 reptile, seven mammal, and six amphibian species. While the wetland is primarily used for water to irrigate the agricultural fields in adjacent villages, it is also a recreation and tourism site.
