The annual festivities centre around entertainments and a market. There is no deliberate disturbance of the waterfowl. |
| Fauna: | The fish fauna includes a variety of common and widespread species. Up to 8,000 ducks winter in the area, roosting on the lake and flighting out to feed in adjacent rice paddies. The predominant species are Dendrocygna javanica, Anas querquedula and A. acuta, with up to 100 Nettapus coromandelianus. Other species known to occur include Anas clypeata, Gallinula chloropus, Porphyrio porphyrio, Fulica atra and Metopidius indicus. Waterfowl recorded during a census in mid-January 1988 included 5,200 D. javanica, 2,565 A. querquedula and 30 A. acuta. |
