BANGKOK, Thailand – The Royal Irrigation Department (RID) has said it is now monitoring the Chao Phraya River Basin as heavy rainfall across the lower North and Central regions increases flows in major waterways, including the Ping and Nan rivers. RID Director-General Witthaya Kaewmee reported that additional upstream runoff is expected from September 24 to 27. To manage the increased flows, the RID will raise discharge from Chao Phraya Dam to about 1,000-1,300 cubic meters per second. The rate could later reach 1,700 cubic meters per second, depending on upstream conditions, to regulate water levels above the dam and accommodate incoming runoff.
The department has issued warnings to governors in 11 provinces across the Chao Phraya River Basin and instructed officials to alert communities that could be affected by rising water levels. Residents along the river and other vulnerable waterways are advised to monitor official updates and prepare for changing conditions. If higher discharge within the 1,500-2,000 cubic meters per second range becomes necessary, the RID will reassess conditions with the Office of the National Water Resources before proceeding with further water management measures.
