The Royal Irrigation Department has issued an urgent warning to those living in low-lying areas along the Chao Phraya River to brace for potential flooding on 21 August. This precaution comes as the department plans to increase water discharge from the Chao Phraya Dam, driven by recent heavy rain.

 

The recent downpour between 15 and 17 August in Thailand’s upper regions has significantly increased the water flow into the Chao Phraya River. This surge necessitates a rise in water discharge from the dam, with expectations set to climb to 1,200-1,500 cubic metres per second over the coming three days.

 

Authorities are closely monitoring the evolving weather conditions and liaising with relevant agencies to assess the situation. The ongoing rainfall points to further potential challenges, as preparations are advised for the next few days.

 

On 21 August, it is predicted that the C.2 Station in the Mueang district of Nakhon Sawan province will report water flow rates between 1,650 to 1,850 cubic metres per second. Combining this with an additional 100 cubic metres per second from local tributaries, the overall water volume above the Chao Phraya Dam in Sapphaya district, Chai Nat province, could reach 1,750 to 1,950 cubic metres per second.

 

This scenario prompts the department to plan an increase in water discharge below the dam to between 1,200 and 1,500 cubic metres per second. Consequently, water levels downstream could rise by approximately 10 to 90 centimetres.

 

Areas most at risk include the Phong Pheng Canal in Ang Thong province, and several zones in Phra Nakhon Si Ayutthaya province, such as the Bang Ban Canal, Hua Wiang subdistrict in Sena district, and Lad Chit and Tha Dindaeng subdistricts in Phak Hai district. Additionally, communities situated along the Noi River within Phra Nakhon Si Ayutthaya need to remain vigilant and prepare for any potential overflow.

 

The Royal Irrigation Department strongly advises residents in these vulnerable areas to stay updated and adopt precautionary measures to mitigate possible flood damage. The department assures that any changes in the situation will be communicated promptly. Residents can reach out to local irrigation offices or contact the department’s hotline at 1460 for further assistance.

 

With forecasts indicating continued heavy rainfall, the focus remains on ensuring public safety and minimising disruption. The upcoming days will be critical for these regions, as authorities work to manage water levels and safeguard communities. In a country where river management is essential, such alerts underscore the ongoing challenges posed by nature and the importance of preparedness in vulnerable areas.
