Chao Phraya Dam to Increase Water Discharge Amid Rising Northern Inflow
The Chao Phraya Dam is preparing to increase its water discharge rate to between 1,000 and 1,300 cubic meters per second due to sustained high water levels from the north.
According to a report by Matichon Online on September 20, 2026, the Chao Phraya Dam is planning to adjust its water discharge rate to a range of 1,000 to 1,300 cubic meters per second. This operational change is a direct response to the continuous increase in water volume flowing down from northern regions, which has necessitated proactive water management measures at the dam.
For residents and travelers in the central plains of Thailand, particularly those living or staying near the Chao Phraya River basin, this development is significant. Increased discharge rates can lead to higher water levels downstream, potentially affecting low-lying areas and riverfront properties. It is advisable for those in the vicinity to monitor local news and official announcements from the Royal Irrigation Department for real-time updates on water levels and potential flood risks.
At this stage, the exact timing of the implementation and the specific impact on downstream provinces remain to be confirmed. Authorities are expected to provide further details as the situation evolves. Residents and visitors are encouraged to exercise caution when near the river and to follow the guidance of local disaster prevention and mitigation agencies.
