Chao Phraya Basin Authorities Issue Flood Warning for Seven Provinces
The Royal Irrigation Department (RID) has alerted seven provinces along the Chao Phraya River to prepare for rising water levels due to increased northern runoff.
On August 24, 2026, the Office of Irrigation 12 (RID 12) issued its third official notification regarding water management in the Chao Phraya River basin. Director Songkran Chalosrithong has formally alerted the governors of seven provinces—Uthai Thani, Chai Nat, Sing Buri, Ang Thong, Suphan Buri, Phra Nakhon Si Ayutthaya, and Lop Buri—to prepare for potential flooding as water levels are expected to rise by 1 to 1.5 meters.
According to Khaosod Online, the current flow at the C.2 station in Nakhon Sawan is measured at 936 cubic meters per second. This influx has caused the water level upstream of the Chao Phraya Dam to reach 15.94 meters, with a discharge rate of 450 cubic meters per second. The RID 12 aims to maintain the upstream level below 16.50 meters to manage the flow effectively.
For residents and travelers in these regions, this development suggests a need to monitor local water levels closely, particularly in low-lying areas near the riverbanks. While the authorities are actively managing the discharge to mitigate impact, the situation remains fluid. It is not yet confirmed how long these elevated water levels will persist or if further adjustments to dam discharge rates will be necessary in the coming days. Visitors are advised to follow updates from local provincial authorities and the Royal Irrigation Department.
