- DDPM alerts 10 provinces and Bangkok for rising Chao Phraya River levels in 1-9 days.
- Chao Phraya Dam must increase downstream water discharge to 700-1,000 cubic meters per second.
- Low-lying areas outside flood embankments will see water levels rise by 0.60 to 1.50 meters.
- DDPM Director-General Theerapat Kachmat urges local units to monitor the situation closely.
The Department of Disaster Prevention and Mitigation (DDPM) has coordinated with 10 provinces along the Chao Phraya River and the Bangkok Metropolitan Administration to prepare for rising river levels over the next 1 to 9 days. This warning follows notifications from the Royal Irrigation Department regarding projected water flow rates at station C.2 in Mueang district, Nakhon Sawan province, expected to reach 1,100 to 1,250 cubic meters per second by September 27, 2026.
Additionally, runoff from tributary rivers is estimated at 50 to 100 cubic meters per second, bringing total water volumes above the Chao Phraya Dam to between 1,150 and 1,350 cubic meters per second. Meanwhile, water intake into irrigation systems on both banks will be maintained at 400 to 450 cubic meters per second to manage the overall water flow.
Due to these rising volumes, the Chao Phraya Dam is required to increase its downstream discharge rate to between 700 and 1,000 cubic meters per second. This operation will directly cause river levels to rise by an additional 0.60 to 1.50 meters above current levels, particularly affecting low-lying communities situated outside the flood embankments, such as Sena district.

Managing water discharge from the Chao Phraya Dam during the late rainy season is a critical operation requiring precise hydrological forecasting. Advance coordination with provinces along the river basin ensures that residents in vulnerable areas outside flood barriers have adequate time to secure belongings and reinforce levees, serving as an essential preventive measure against property and agricultural damage.
"The Central Disaster Prevention and Mitigation Command has been informed by the Royal Irrigation Department that water flow forecasts over the next 1-9 days require an increase in downstream dam discharge."
Theerapat Kachmat, Director-General of the DDPM
Theerapat Kachmat, Director-General of the DDPM, urged all affected provincial authorities to issue timely warnings to residents living along both banks of the Chao Phraya River, as well as operators of riverside businesses such as floating restaurants and water transport services. Local agencies have been instructed to place rescue personnel and equipment on standby to assist citizens promptly in case of emergencies.
