|
|
| Disturbances and threats: | Cultivation of the steep slopes around the lake has resulted in severe soil erosion and siltation in the lake. |
| Economic and social values: | The lake supports a small fishery, yielding 40-50 metric tonnes per year, and is an important source of water for irrigation. |
| Fauna: | The lake and adjacent swamps are known to be important for waterfowl, but no details are available. The Siamese Crocodile Crocodylus siamensis formerly occurred in the area, but has not been recorded in recent years. |
| Special floral values: | No information. |
