Bangkok: Seven provinces in the Chao Phraya River basin have been warned to brace for a potential rise in water levels due to increased water discharge from upstream, which could result in levels rising by 1-1.50 meters.
According to Thai News Agency, Mr. Songkran Chalorsrithong, Director of Irrigation Office Region 12, has issued a water situation and management advisory, Notice No. 3, to the governors of the affected provinces: Uthai Thani, Chainat, Sing Buri, Ang Thong, Suphan Buri, Phra Nakhon Si Ayutthaya, and Lop Buri. The advisory highlights the rapid increase in water levels from the upper Chao Phraya River Basin, influencing the flow upstream of the Chao Phraya Dam. As of August 24, 2026, at 06:00 AM, the water flow at station C.2 in Nakhon Sawan Province was recorded at 936 cubic meters per second, contributing to a rise in the upstream water level of the dam to +15.94 meters above mean sea level.
The current water flow through the Chao Phraya Dam stands at 450 cubic meters per second, with efforts to maintain the upstream water level at a maximum of +16.50 meters above mean sea level. Projections indicate that the water flow through the dam could increase to approximately 500-700 cubic meters per second. Residents and officials in the affected areas are urged to disseminate this information, stay informed, and closely monitor the evolving water situation.
