Flood damage in Thailand’s Nakhon Phanom Province has been provisionally estimated at approximately 90,000 rai of farmland. As of August 18, 2026, the estimated affected area was 90,781.70 rai, including 89,985.20 rai of rice-growing land.
How extensive is the damage?
The provisional count covered 11 districts, 69 subdistricts, and 444 villages, with 12,538 affected farmers reported. A report published on August 26 subsequently said that 11 of Nakhon Phanom Province’s 12 districts, excluding Wang Yang District, had been declared flood disaster areas.
The reported farmland damage is a provisional estimate, not a final confirmed figure.
Why flooding may continue even as the Mekong River level falls
Nakhon Phanom local authorities announced and reports noted that water from major tributaries could affect farmland even if the Mekong River level declines. Therefore, it is difficult to assess flooding conditions across different areas uniformly based only on changes in the level of the Mekong’s main channel.
The Thai Meteorological Department posted a map of areas at risk of heavy rain in Thailand as of 17:00 on August 27, 2026. However, the provided materials do not allow confirmation of real-time water levels or discharge volumes in the Nam Un tributary, or real-time flooded-area figures by district.
What readers should check
- Confirm the date of the provisional farmland damage estimate.
- Do not interpret the figures as meaning that all 11 districts experienced the same level of damage.
- Immediately before publication, recheck the latest water-level, rainfall, and evacuation guidance from local authorities and the Thai Meteorological Department.
