Bangkok: The Royal Irrigation Department (RID) has heightened its efforts to manage water discharge from major dams as Tropical Storm “Bualoi” approaches. The department is working closely with governors and the Department of Disaster Prevention and Mitigation (DDPM) to elevate warnings for potential flash floods and landslides, especially in the mountainous northern regions.
According to Thai News Agency, Mr. Paitoon Kengkarnchang, Deputy Secretary-General of the Office of National Water Resources (ONWR), convened a meeting with relevant agencies to evaluate the water situation as Thailand braces for the storm. The meeting concluded with a decision to increase the water discharge rate from large dams to better prepare for the anticipated heavy rainfall in late September, particularly affecting the northern and upper northeastern regions.
In the Chao Phraya Basin, adjustments have been made to the water release from the Sirikit Dam, increasing from an original 10 million cubic meters per day to 15 million cubic meters. The Bhumibol Dam has followed suit with a similar increase to maintain dam integrity and facilitate rainwater harvesting. Meanwhile, the Pasak Jolasid Dam continues to release water at a rate of 51.87 million cubic meters per day as it approaches full capacity. The water situation upstream of the Chao Phraya Dam is also under close observation, with changes in release rates to help manage water levels in Chai Nat, Uthai Thani, Phra Nakhon Si Ayutthaya, and Ang Thong provinces.
In the northeastern region, the Ubonrat Dam is systematically increasing its water release, now at 35 million cubic meters per day, with downstream impact mitigation plans in place for Khon Kaen, Maha Sarakham, Roi Et, and Yasothon provinces. The focus remains on mountainous northern areas, where Prime Minister Anutin Charnvirakul has highlighted the risks of flooding, flash floods, and landslides. The National Water Resources and Disaster Prevention and Mitigation Office (NWR) is actively coordinating with provincial governors and the DDPM to bolster disaster warnings, particularly in vulnerable provinces such as Chiang Mai, Chiang Rai, Mae Hong Son, Phrae, and Nan.
The ONWR, in partnership with the Meteorological Department and the Hydro-Informatics Institute, will continue to monitor weather developments and adjust water management strategies as necessary to address the challenges posed by Tropical Storm “Bualoi.”
