The Office of National Water Resources is preparing to adjust water management plans for reservoirs nationwide in line with the El Niño situation, while forecasting that one to two storms will pass through Thailand between August and October. Mr. Phaitoon Kengkarnchang, Deputy Secretary-General of ONWR, disclosed after the 9th meeting of the Climate Analysis Working Group for 2026 that the southeast monsoon and monsoon trough will bring increased rainfall from late July to mid-August, especially in the Northeast, East, and western southern regions. The meeting resolved that the Royal Irrigation Department and the Electricity Generating Authority of Thailand should urgently adjust water discharge plans to not fall below the minimum water level control threshold, in order to reserve water for a potentially prolonged dry season. As of July 21, 2026, 35 large reservoirs held a combined volume of 39.75 billion cubic meters, representing 56 percent of storage capacity, which is approximately 2.62 billion cubic meters less than in 2025. Eight reservoirs have relatively low water levels, such as Pasak Jolasid Reservoir at only 12 percent of capacity and Khlong Si Yat Reservoir at just 14 percent. ONWR confirmed that the available water supply will be sufficient for consumption and ecosystem maintenance, but the agricultural sector must rely primarily on rainfall and use reservoir water only during dry spells. All agencies are urged to strictly follow the 2026 rainy season measures, particularly inspecting waterway obstructions to prevent flooding.
