23 Major Dams Across Thailand Near or Exceed Capacity as of 10 Nov 2025

23 major dams across Thailand are nearing or exceeding full capacity as of 10 Nov 2025. The Chao Phraya Dam has increased its water discharge to 2,900 cubic meters per second, causing higher water levels downstream.

Today (10 Nov). The Meteorological Department. Northern Thailand has decreasing rainfall but still experiences scattered thunderstorms due to a low-pressure area covering the western part of the north and Myanmar. Residents in these areas are advised to be cautious of thunderstorm hazards. Farmers should take precautions to protect agricultural products. In the south, thunderstorms continue due to the southwest monsoon prevailing over the Andaman Sea, southern Thailand, and the Gulf of Thailand. Wave conditions in the Andaman Sea are moderate, with waves 1–2 meters high.

Meanwhile, typhoon "Fung-wong" (Fung-wong) near the Philippines is expected to move toward the upper South China Sea and the Taiwan Strait between 12–13 Nov 2025. This typhoon will not enter Thailand.

Chao Phraya Dam increases water discharge.

On 10 Nov 2025 at 13:18, the Chao Phraya Dam announced an increase in water discharge from 2,800 cubic meters per second to 2,900 cubic meters per second starting at 02:00 on 11 Nov 2025, an approximate increase of 10 cubic meters per second per hour, maintaining this rate continuously.

The Chao Phraya Dam retains water upstream, causing the area above the dam, including Sala Dan Subdistrict, Manorom District, Chainat Province, to be affected by flooding for the fourth consecutive time in less than two months. Residents have had to evacuate to roadside areas or second floors as all riverside homes are fully inundated, with water levels over one meter. Severe damage has occurred to farmers' crops, including bananas, beans, corn, and pomelos, affecting nearly 100 rai. Prolonged flooding could cause pomelo roots to rot and die, resulting in losses worth millions of baht.

Nonglak Ngamyu Charoen, a resident of Sala Dan, said this is the fourth flood with water rising and falling repeatedly. They have cleaned and repainted their homes three times. The first three floods were manageable, but this time the water rose rapidly at night, leaving little time to move belongings. Authorities released water without informing or explaining to residents. Various vegetables planted, such as eggplants, long beans, bitter gourds, and melons, were destroyed. They cannot plant vegetables now, even though planting should begin soon with harvesting expected in February. Sala Dan residents supply nearly 15 tons of vegetables daily to Talad Thai market, but planting has been disrupted by persistent flooding. This year's flooding is worse and longer-lasting than in 2022. Normally, floods last about a month, but this one has come and gone over two months.

Supap Suk Samran, a 74-year-old pomelo farmer, said the flood has killed small pomelo trees. Larger trees will die from root rot if flooded for another month. Even if they survive, fruit quality will decline. Compensation is inadequate as it only covers plants that have died, and pomelo trees are perennial, not annual crops. Compensation is only about 1,000 baht per rai, insufficient for the 3–5 years needed for pomelos to bear fruit. Farmers in Sala Dan have over 10 rai planted with about 400 trees, each yielding around 200 kilograms valued at 10,000 baht per tree. Total losses could reach 4 million baht. As the trees grow, they face repeated flooding, forcing farmers to watch helplessly as their pomelos die before their eyes.
