Chao Phraya Dam Increases Water Discharge Amid Heavy Rainfall
The Royal Irrigation Department has increased water discharge from the Chao Phraya Dam to 1,750 cubic meters per second to manage rising water levels.
According to a report by Prachachat Business on September 24, 2026, the Royal Irrigation Department (RID) has adjusted the water discharge rate at the Chao Phraya Dam to 1,750 cubic meters per second. This decision follows an influx of water from northern regions, with the C.2 station in Nakhon Sawan recording a flow of 1,777 cubic meters per second.
To manage the situation, the RID is raising water levels upstream of the dam to slow the flow and maximize the intake of water into irrigation systems on both sides of the river. These measures are being implemented in anticipation of continued rainfall expected through September 27, 2026.
For residents and travelers in low-lying areas along the Chao Phraya River, this adjustment may lead to higher water levels in the riverbanks. It is important to monitor local announcements regarding potential flooding or changes in water management. While the RID is actively managing the flow to mitigate risks, the full impact of the rainfall through September 27 remains to be confirmed. Residents are advised to stay updated through official government channels for any safety warnings or travel advisories in affected provinces.
