The lake itself, with depths ranging from two to eleven metres, has a diversity of aquatic life. This includes several dozen species of macrophytes (plants growing in or near water), phytoplankton and zooplankton (microscopic plants and animals), and fish species such as the Cyprinus carpio (common carp) and Danio aequipinnatus (or giant danio), and species of Garra, Schistura and Schziothorax. Such diversity is indicative of a healthy lake (though some of the fish were introduced). In the distance, at the far end of the lake, we saw an almost totally white water bird and excitedly realised it was a goosander &mdash not a common bird in other parts of India. The region is an important wintering area for migratory birds, or resting spot for resident species, including the bar-headed goose, the ruddy shelduck, Baer&rsquos pochard, black-necked grebe, merganser, tufted duck, teals, and the rare black-tailed crake. There is even one record of a black-necked crane, which is counted among India&rsquos most threatened species. Khecheopalri is considered important enough for NGOs like the World Wildlife Fund and the Salim Ali Centre for Ornithology and Natural History to recommend its inclusion in the Ramsar list of wetlands of international importance.
