Chao Phraya Dam Increases Water Discharge, Warning Issued for Downstream Areas
The Chao Phraya Dam has begun a phased increase in water discharge to 1,200 cubic meters per second, prompting warnings of rising water levels for downstream communities.
According to a report by Matichon Online on September 21, 2026, the Chao Phraya Dam has initiated a phased increase in its water discharge rate, reaching 1,200 cubic meters per second. This operational adjustment is intended to manage water levels effectively within the dam's reservoir.
Authorities have issued a formal warning to residents and businesses located downstream of the dam. Water levels in these areas are expected to rise by approximately 30 to 60 centimeters as a result of the increased flow.
For residents and travelers in the affected regions, this development is significant as it may lead to localized flooding or increased water currents along the riverbanks. Those living or staying near the Chao Phraya River should monitor local news updates closely and follow any instructions provided by provincial authorities.
At this stage, it remains to be confirmed how long this discharge rate will be maintained and whether further increases will be necessary depending on upstream rainfall patterns. Travelers planning trips to riverside destinations in the central provinces should exercise caution and verify the status of local river conditions before proceeding. The situation is currently being monitored by water management officials to ensure public safety.
