Khlong Song crisis! Dead fish continue to accumulate, with rotting carcasses piled up at Bongkot 67 Bridge. The strong stench causes dizziness among locals, who urge relevant agencies to promptly remove the carcasses, identify the cause, and push out the polluted water.
On 16 Oct 2026, reporters inspected the area along Khlong Song near Bongkot 67 and Bongkot 50 alleys, in front of Village Rangsit Khlong Song housing estate, and throughout the canal in Khlong Song subdistrict, Khlong Luang district, Pathum Thani province, following continuous large-scale fish deaths since 15 October.
Latest checks this morning revealed an increased number of decaying fish carcasses floating on the water surface compared to the previous day. The strong foul odor pervades the area, severely troubling residents living along the canal banks.
Investigation found that the large accumulation of fish carcasses near Bongkot 67 Bridge resulted from the opening of the water gates to accelerate drainage. The water current carried the decomposing fish, which had accumulated earlier, to collect at the spot where officials had placed pipes as a barrier.
Mrs. Prayad, a local resident, expressed distress that since morning the number of dead fish increased noticeably, and the strong rotten smell caused dizziness and loss of appetite. She had to keep her house doors tightly closed and use fans to repel the odor. She urged relevant authorities to urgently send personnel to scoop up and remove the carcasses.
Earlier on 15 Oct, Mr. Yuttisak Chuprasert, Mayor of Khlong Luang Municipality, led officials to collect fish carcasses along more than three kilometers of Khlong Song, removing over 20 tons for burial. They also sprayed effective microorganisms (EM) and spread lime to reduce odor and minimize environmental impact.
Additionally, Khlong Luang Municipality coordinated with the Royal Irrigation Department and the Department of Fisheries to jointly address the issue. They requested increasing the northern water gate opening by 10 centimeters to speed up pushing out polluted water and enhance water circulation. Locals noted that before the mass fish deaths, the canal water was already dark and emitting a foul odor.
Relevant agencies are preparing to inspect the water quality and thoroughly investigate the cause of the fish deaths to develop solutions and prevent long-term effects on the public.
