ONWR Accelerates Water Drainage Ahead of Expected October Rainfall
The Office of the National Water Resources (ONWR) is increasing water discharge rates toward the Gulf of Thailand to prepare for heavy rain forecasted for October 5–7.
According to a report by Matichon Online, the Office of the National Water Resources (ONWR) is currently accelerating the drainage of water into the Gulf of Thailand. This proactive measure is designed to create capacity in major reservoirs, specifically the Bhumibol and Sirikit dams, which are being utilized to hold back water from upstream regions.
This strategic water management effort is being implemented in anticipation of a new round of rainfall forecasted to impact the country between October 5 and October 7, 2026. By lowering water levels in these critical dams now, authorities aim to mitigate potential flooding risks associated with the upcoming weather system.
For residents and travelers, this news is significant as it highlights ongoing efforts to manage water levels across the country. While the ONWR is actively working to prevent overflow, those in low-lying areas or regions near major waterways should remain informed about local water conditions. It remains to be confirmed how much rainfall will actually materialize during the October 5–7 period and whether these drainage efforts will be sufficient to prevent localized flooding in downstream areas. Travelers are advised to monitor local weather reports and official announcements from the Thai Meteorological Department for updates on potential travel disruptions.
