Chao Phraya Dam Boosts Release to 2,500 Cubic Meters Tonight
The Chao Phraya Dam will raise its water discharge to 2,500 cubic metres per second starting tonight, increasing gradually to that level by early 2 October. Officials assure that Bangkok and surrounding areas will not be affected as long as no additional rain occurs. Current monitoring shows flows remain well within the capacity limits for the capital region.
The Chao Phraya Dam will increase its discharge to 2,500 cubic metres per second starting tonight, with the rate rising gradually to that level by 03:00 on 2 October. Officials say the current water volume will not impact Bangkok and the surrounding area as long as no additional rain falls. The Royal Irrigation Department reported that flow at the C.2 station in Nakhon Sawan is 2,528 cubic metres per second, plus 576 from the Sakhaeng River, pushing the upstream level to +17.86 metres. The dam is currently releasing 2,400 cubic metres per second. The increase will be made in steps, averaging an additional 15 cubic metres per second each hour. Water levels upstream are expected to peak at 2,900–3,000 cubic metres per second in about two days, which combined with the Sakhaeng River and side inflows of roughly 600 cubic metres per second brings the total to manage at about 2,900 cubic metres per second. The Irrigation Department has been raising releases from 2,200–2,300 cubic metres per second earlier this week to 2,400 this afternoon, staying below the 2,500 limit. At the key monitoring point in Bang Sai district, Ayutthaya province, the flow is 2,173 cubic metres per second, well within the 3,500 cubic metres per second capacity for Bangkok and the vicinity.
