Flood Alert Issued for Chao Phraya River Basin
Authorities have warned residents and travelers in 10 central provinces and Bangkok to monitor rising water levels along the Chao Phraya River from August 27 to September 2, 2026.
On August 27, 2026, the Department of Disaster Prevention and Mitigation (DDPM), acting as the Central Disaster Prevention and Mitigation Command, issued an alert regarding the Chao Phraya River basin. According to reports from Khaosod Online, the Royal Irrigation Department has projected an increase in water levels over the coming days.
Forecasts indicate that by August 28, the water flow at the C.2 station in Nakhon Sawan province is expected to reach between 1,000 and 1,100 cubic meters per second. When combined with water from tributaries, the total volume upstream of the Chao Phraya Dam is anticipated to range from 1,100 to 1,200 cubic meters per second. Consequently, authorities have requested that 10 central provinces and Bangkok remain vigilant for potential water level fluctuations between August 27 and September 2, 2026.
For residents and travelers, this situation may lead to localized flooding in low-lying areas along the riverbanks. It is important to monitor local news and official government announcements for updates on flood management and potential impacts on river transport or riverside activities. While the current projections provide a window for preparation, the exact extent of the water level rise remains subject to ongoing monitoring by the Royal Irrigation Department. Travelers are advised to check local conditions before visiting riverside destinations in the affected central region.
