Pathum Thani Authorities Manage Massive Fish Die-off in Rangsit Canal
Local officials are working to remove over 30 tons of dead tilapia from the Rangsit Canal following a significant drop in water oxygen levels.
On October 16, 2026, authorities in Pathum Thani province launched an emergency operation to clear more than 30 tons of dead fish from the Rangsit Canal near the Wat Saeng San sluice gate in Thanyaburi district. According to Khaosod Online, the cleanup effort is being led by Pathum Thani Provincial Administrative Organization President Kamronwit Thoopkrachang and the Royal Irrigation Department.
Officials identified the primary cause of the die-off as a severe depletion of oxygen in the water, resulting from the discharge of stagnant, polluted water from local communities into the canal system. The incident has primarily affected tilapia populations. To mitigate the environmental impact and prevent further health hazards, crews are using boats and specialized equipment to remove the carcasses and are flushing the area with fresh water to improve water quality.
For residents and visitors in the area, the situation serves as a reminder to avoid contact with canal water until authorities confirm that water quality has returned to safe levels. While the immediate cleanup is underway, the long-term impact on the local ecosystem and the specific timeline for full water restoration remain to be confirmed by environmental agencies. Authorities continue to monitor the canal to prevent further contamination.
