Chao Phraya Dam Water Discharge Limits Clarified by Deputy PM
Deputy Prime Minister Thongsak has clarified that the Chao Phraya Dam will maintain a discharge rate of 2,200 cubic meters per second, despite requests for a higher volume.
According to a report by Matichon Online on September 30, 2026, Deputy Prime Minister Thongsak addressed public concerns regarding potential water discharge increases at the Chao Phraya Dam. While there were reports suggesting the dam requested to release water at a rate of 2,500 cubic meters per second, the Office of the National Water Resources (ONWR) has officially approved a limit of only 2,200 cubic meters per second.
For residents and travelers in Thailand, this clarification is significant as it relates to flood management and water levels in downstream areas. Maintaining the discharge at the lower approved rate is intended to manage water flow effectively while mitigating the risk of flooding in surrounding provinces.
While the government has set this current threshold, the situation remains subject to change depending on ongoing weather patterns and rainfall accumulation. Residents living near the riverbanks or those planning travel to low-lying areas along the Chao Phraya basin should continue to monitor official updates from the Royal Irrigation Department and local authorities. As of now, the 2,200 cubic meters per second limit is the active policy, and any future adjustments to this discharge rate will depend on further assessments by the ONWR.
