Biogeographical Province:
Wetland type:
14 & 19.
Description of site:
A freshwater lake of about 1,760 ha, surrounded by approximately 2,360 ha of marshland which fringes the entire shoreline and extends back as far as 1.5 km; one of the largest natural wetlands in the northeast part of the country. The lake extends for seven km from north to south and three km from east to west at its widest point. The main inflow is from the Huai Phai Chan Yai, which flows off the highlands to the east, but there are other smaller streams entering from the north and west. The outflow is at the south end of the lake, into the Lam Pao river system. The lake is shallow (mostly less than one metre deep) and permanent, with considerable seasonal fluctuations in water level. There is a fairly high human population density around the lake shore, scattered chiefly among seven small villages.
Climatic conditions:
Tropical monsoonal climate with an average annual rainfall of 1,367 mm (range 929-1,997 mm), 87.5% of which falls during the southwest monsoon (May to October). The mean annual temperature is 26.8°C (range 2.5-43.9°C).
Principal vegetation:
Scirpus grossus, Eichhornia crassipes, Nelumbo nucifera and many short grasses. Chiefly cultivation in adjacent areas, with some patches of dry dipterocarp woodland remaining, especially on the uplands.
Land tenure:
The site is state owned and open to public use; surrounding areas are mainly privately owned farmland.
Conservation measures taken:
Conservation measures proposed:
The site should be surveyed to determine its present status and conservation importance. It may be suitable for establishment as a Non-Hunting Area.
Land use:
Fishing and the raising of domestic ducks; cultivation in surrounding areas, mainly cassava and sugar cane, with some areas of single crop rice (one wet-season crop per year).
Possible changes in land use:
Disturbances and threats: The lake appears to be silting up. The levels of disturbance by fishermen are very high and probably limit the utilization of the site by waterfowl.
Economic and social values: The wetland is important as a source of water for local use. Although there is no irrigation project at the site, water is hand-carried by local people for household use.
Fauna: No information.
Special floral values: No information.
