Flood Warning Issued for Four Provinces Along the Chao Phraya River
The Department of Disaster Prevention and Mitigation has issued a flood alert for four provinces as water levels are expected to rise due to increased discharge from the Chao Phraya Dam.
On September 24, 2026, the Department of Disaster Prevention and Mitigation (DDPM) issued an urgent warning for four provinces situated along the Chao Phraya River basin. According to the Director-General of the DDPM, Theerapat Kachamat, the agency received notification from the Royal Irrigation Department regarding a significant increase in water flow.
Projections indicate that water passing through the C.2 station in Nakhon Sawan will reach approximately 1,800 cubic meters per second, supplemented by an additional 300–400 cubic meters per second from tributaries. Consequently, the Chao Phraya Dam is expected to discharge water at a rate of 1,500–2,000 cubic meters per second. This operation is anticipated to cause water levels downstream to rise by approximately 0.70 to 1.70 meters.
For residents and travelers in the affected areas, this development necessitates heightened vigilance. Local authorities, including the Bangkok Metropolitan Administration and regional disaster centers, have been instructed to monitor the situation around the clock and provide continuous updates to the public. While the discharge is a controlled measure to manage upstream volume, those living or traveling near riverbanks should remain alert to potential flooding and follow instructions from local officials. It remains to be confirmed exactly which specific districts will experience the most significant impact as the water moves downstream over the coming days.
