National Water Resources Management Committee Identifies 13 Major Dams at Risk of Shortages

Bangkok: Urgent! The National Water Resources Management Committee (NWRC) reveals the names of 13 major dams at risk of water shortages and warns the entire country to prepare for heavy rainfall from August 14-16.

According to Thai News Agency, the National Water Resources Office (NWRO) released a report summarizing the overall water situation in Thailand as of August 13, 2026. The report stated that the overall water volume in reservoirs nationwide was at 59% of their storage capacity, with usable water at 41%, amounting to approximately 23,265 million cubic meters. The report also issued warnings for areas at risk due to the influence of a monsoon trough passing over the northern and upper northeastern regions, combined with a relatively strong southwest monsoon, resulting in continued heavy rainfall in some areas across all regions. Heavy rainfall is expected to increase in many areas of Thailand from August 14 to 16.

Meanwhile, the NWRO revealed information on reservoirs requiring special monitoring because they have usable water volumes below 30%, or below the minimum control level. These include 13 large reservoirs spread across several regions, such as the Khwae Noi Bamrung Dan, Mae Mok, and Thap Sala dams in the North; the Pa Sak Chonlasit and Krasiew dams in the Central region; the Ubolratana, Chulabhorn, Lam Takhong, and Mun Bon dams in the Northeast; the Khlong Si Yat and Narubadin Chinda dams in the East; and the Vajiralongkorn and Pranburi dams in the West. In addition, 60 medium-sized reservoirs nationwide were also found to have water levels below 30%.

Regarding the water situation in the Eastern Economic Corridor (EEC), the three main dams - Bang Phra Dam at 45% capacity, Nong Pla Lai Dam at 52%, and Prasae Dam at 66% - have sufficient water. However, based on the management and assessment of the situation, the NWRC confirms that the overall water supply in the country remains sufficient for consumption, domestic use, and various water-related activities until the end of the dry season in 2026 and into 2027.
