Mass Fish Die-off Reported in Pathum Thani Canals
Authorities are investigating a significant fish die-off near the Pak Khlong Soi 1 sluice gate in Pathum Thani, suspected to be caused by deteriorating water quality.
On October 15, 2026, reports emerged from Khaosod Online regarding a mass fish die-off at the Pak Khlong Soi 1 sluice gate, located within the Rangsit Tai irrigation project in Thanyaburi, Pathum Thani. Local observers noted large numbers of dead fish floating on the water's surface, while surviving fish were seen struggling to breathe at the surface. Similar conditions have been reported in the nearby Khlong Song area.
Initial assessments suggest that the incident may be linked to poor water quality resulting from recent accelerated water drainage operations in the area. The decomposing fish have begun to emit a foul odor, prompting local municipal authorities to apply fermented water solutions to mitigate the smell.
For residents and visitors in the area, the situation raises concerns regarding environmental health and the overall quality of the canal water. While the municipality is actively managing the immediate odor issues, the long-term impact on the local ecosystem remains to be confirmed. Authorities have not yet provided a definitive analysis of the water contaminants, and residents are advised to remain cautious near the affected waterways until further updates are provided by the irrigation department.
