Nanda Lake comprises intermittent freshwater marshes that lie adjacent to one of the major tributaries of the Zuari River. They are linked to the adjacent river channel by a sluice gate, which when closed enables the flooding of the marshes. This wetland supports a wide variety of migratory waterbirds and many other important plants and animals. Notable bird species include black-headed ibis (Threskiornis melanocephalus), common kingfisher (Alcedo atthis), wire-tailed swallow (Hirundo smithii), bronze-winged jacana (Metopidius indicus), brahminy kite (Haliastur indus), intermediate egret (Ardea intermedia), little cormorant (Microcarbo niger) and lesser whistling duck (Dendrocygna javanica). The Site enables local communities to store water during the off-monsoon season, to cultivate rice paddies downstream of the lake and support fishing and recreation. The lake also protects downstream areas from monsoon floods. Threats include invasive non-native species, garbage and solid waste, overfishing, and harvesting of aquatic resources. However, there is no management plan to address these issues.
