Chao Phraya River Water Discharge Increased Following Heavy Northern Rainfall
The Royal Irrigation Department has increased water discharge from the Chao Phraya Dam to 900 cubic meters per second due to rising water levels from recent heavy rains in Northern and Central Thailand.
According to Khaosod Online, the Royal Irrigation Department is closely monitoring the Chao Phraya River basin following significant rainfall between November 5 and 7, 2026. Heavy precipitation was recorded in provinces including Uthai Thani, Phitsanulok, and Kamphaeng Phet, leading to increased runoff into the Ping, Nan, and Sakae Krang rivers. This influx has caused water levels upstream of the Chao Phraya Dam to rise. As a result, Director-General Witthaya Kaewmee announced that the dam's discharge rate was increased from 800 to 900 cubic meters per second as of the morning of November 10. Officials anticipate that water levels from Nakhon Sawan and the Sakae Krang River will continue to rise through November 13 before gradually subsiding. For residents and travelers in low-lying areas along the Chao Phraya River, this adjustment is a precautionary measure to manage the incoming volume and mitigate potential flooding impacts. While authorities are actively managing the situation, those in the vicinity should remain alert to local announcements regarding water levels. It remains to be confirmed how long these elevated discharge rates will be maintained and whether further adjustments will be necessary depending on subsequent weather patterns.
