Chao Phraya River Basin on Alert as Water Discharge Increases
Thai authorities are managing rising water levels in the Chao Phraya River, with discharge rates from the Chao Phraya Dam expected to reach up to 1,000 cubic meters per second.
According to Khaosod Online Thailand, the Ministry of Agriculture and Cooperatives is monitoring rising water levels in the Chao Phraya River basin due to persistent rainfall in the country's northern regions. Minister Suriya Juangroongruangkit has directed relevant agencies to coordinate efforts to mitigate potential flooding and provide assistance to affected areas.
The Royal Irrigation Department (RID) reports that water flow at the C.2 station in Nakhon Sawan is projected to reach 1,000–1,100 cubic meters per second by August 28, 2026. Consequently, the RID is managing the inflow to the Chao Phraya Dam and adjusting discharge rates to between 700 and 1,000 cubic meters per second. This adjustment is expected to raise water levels downstream by approximately 0.60 to 1.50 meters.
For residents and travelers, this situation may lead to localized flooding in low-lying areas outside of flood embankments, specifically in districts such as Sena. While the authorities are actively managing the flow to minimize impact, those in riverside communities should remain vigilant and monitor local updates. It remains to be confirmed how long these elevated discharge rates will persist and whether further adjustments will be necessary depending on future rainfall patterns.
