Thailand Launches 2026/27 Dry Season Water Management Plan
The Royal Irrigation Department has initiated its dry season water management strategy, prioritizing essential consumption and ecosystem maintenance while preparing for potential rainfall shortages in 2027.
The Royal Irrigation Department (RID) officially commenced its water management plan for the 2026/2027 dry season on November 1, 2026, following the conclusion of the rainy season. According to Khaosod Online, the department is prioritizing water allocation for household consumption and the preservation of ecological systems. Santi Tem-iam, an expert in irrigation engineering and assistant to the RID director-general, stated that the strategy involves careful monitoring of water reserves to ensure sufficient supply during the early rainy season of 2027, which faces a risk of rainfall gaps between May and July.
As of November 2, 2026, national water reserves in large and medium-sized reservoirs stand at 63.98 billion cubic meters, representing 83% of total capacity. The four primary dams in the Chao Phraya river basin—Bhumibol, Sirikit, Kwae Noi Bamrung Daen, and Pasak Jolasid—collectively hold 18.94 billion cubic meters, or 76% of their capacity. For residents and travelers, this proactive management aims to ensure stable water availability across the country. While current levels appear robust, the department continues to analyze regional trends to adjust distribution as needed. Future updates will clarify how these reserves perform against the anticipated dry spells in mid-2027.
