The Tonle Sap Authority has completed nearly 25 percent of a demarcation process on the Tonle Sap reservoir that will designate areas where water-collecting reservoirs are illegal. Chan Yutha, secretary general of the Tonle Sap Authority, said 178 of a planned 802 demarcation posts had been planted. The area has been plagued with illegal man-made reservoirs, which collect water for rice growing in the dry season. He said the government has allocated US$250,000 to destroy the reservoirs and complete the demarcation process.
