Chao Phraya Dam Increases Water Management Measures Amid Heavy Rain Forecast
The Royal Irrigation Department is proactively managing water levels at the Chao Phraya Dam to mitigate potential flooding as rainfall increases.
On September 24, 2026, the Director-General of the Royal Irrigation Department, Witthaya Kaewmee, inspected the Chao Phraya Dam in Chai Nat province to oversee water management strategies. Following consistent rainfall in northern regions, the dam recorded a water flow of 1,777 cubic meters per second at the C2 station in Nakhon Sawan as of 6:00 AM.
To prevent rapid flooding in downstream areas, officials are currently regulating water levels by holding back water upstream and diverting it into irrigation systems. The dam is maintaining a discharge rate of 1,750 cubic meters per second. These measures are designed to balance the incoming flow with the capacity of the river system.
This situation is particularly relevant for residents and travelers in the Central region, as the Thai Meteorological Department has forecasted increased rainfall through September 27, 2026. While upstream water levels have begun to stabilize, the additional rain could lead to rising water levels in the Chao Phraya basin. Authorities have issued warnings to provinces located downstream and are providing continuous updates to the public. Travelers in the area are advised to monitor local news and follow instructions from provincial authorities regarding potential water level changes. It remains to be confirmed how much the upcoming rainfall will impact the total volume of water in the basin over the next few days.
