The Chao Phraya Dam has continuously reduced its discharge from 2,400 to 2,350 cubic meters per second, while flooding conditions in Phonangdamok Subdistrict, Sapphaya District, Chai Nat Province, remain unresolved.
On 8 Oct 2026 GMT+7, reporters noted that water levels in the Chao Phraya basin have been steadily declining. The Royal Irrigation Department has gradually lowered the dam's discharge from 2,400 to 2,350 cubic meters per second to reduce downstream impact and to prepare for incoming heavy rains forecasted from 9 to 13 Oct 2026 GMT+7. The Meteorological Department has warned of unstable weather across Thailand, including thunderstorms, strong winds, hail, and locally heavy to very heavy rainfall during this period.
Currently, water flow at the C.2 measuring station in Mueang District, Nakhon Sawan Province, is 2,009 cubic meters per second. At station C.13 at the Chao Phraya Dam in Sapphaya District, Chai Nat Province, upstream water level is 16.05 meters above mean sea level, downstream level is 15.58 meters, and the dam is releasing water at 2,350 cubic meters per second.
Although the Chao Phraya River's water level is decreasing, some areas remain affected by flooding, especially low-lying communities adjacent to waterways. In Phonangdamok Subdistrict, Sapphaya District, Chai Nat Province, over seven subdistricts are still impacted, with more than 1,412 households affected. Floodwaters in some locations have become discolored and emit unpleasant odors. Multiple agencies continue to provide ongoing assistance in the area.
Additionally, the Phonangdamok Subdistrict Municipality in Sapphaya District has established a service center for residents to register for flood relief funds from the Department of Disaster Prevention and Mitigation. This center, located at the municipality’s emergency flood relief operations center, aims to reduce travel burdens for affected residents.
Pirom Thosuwan, Deputy Mayor of Phonangdamok Subdistrict Municipality, Sapphaya District, Chai Nat Province, said that floodwaters have receded by about 40 centimeters. However, residents still face hardships. The municipality and various sectors are intensifying coordinated efforts to provide support, including drinking water, sanitation facilities, and electricity.
For residents who have relocated to the roadside along the Maharaj canal embankment, stagnant floodwaters in some areas have begun to emit foul odors. The municipality is urgently addressing this by coordinating with relevant agencies to obtain EM (Effective Microorganisms) solutions for treating the polluted water to improve its condition. The situation is expected to improve soon.
Nevertheless, residents remain vigilant and prepared, as in previous years they have experienced two to three flood events. Some households have yet to move belongings from elevated areas and continue monitoring weather warnings issued by the Meteorological Department to stay ready for incoming rains.
