The Opole Voivode, Sławomir Kłosowski, during the crisis staff on June 11, agreed with the fire brigade to urgently start water oxygenation in sections of the canal where the lowest level of oxygen saturation was found, which could be the reason for the death of fish, the Ministry of Climate and Environment announced on Sunday. “If the unfavorable situation persists, the Opole voivode is considering (…) a ban on the use of the waters of the Gliwice Canal. A possible ban will not apply to shipping on the canal,” Kłosowski said on social media. Earlier, over 450 kilograms of dead fish were found in the waters of the Gliwice Canal.

The Ministry of Climate and Environment (MKiŚ) announced on Sunday that the Opole Voivode, Sławomir Kłosowski, during the crisis staff convened on June 11, agreed with representatives of the Provincial Headquarters of the State Fire Service (KW PSP) to “urgently” start water oxygenation in sections of the canal where the lowest level of oxygen saturation was found which may have caused the fish to die. “Further remedial action is being considered,” it said. On June 10, the Ministry of Culture and National Heritage announced that Over 450 kg of dead fish were collected in the Gliwice Canal. It was then found that the likely cause was a sharp drop in the oxygen content of the water. It has dropped to 45% in some places.

“The rapid decrease in oxygen in the water could have led to the death of the fish. The analysis of water tests from the canal is still ongoing. The results of the samples from June 10 show the presence of golden algae in the Kędzierzyn Canal and in two locations in the Gliwice Canal. The algae may have moved with the current. The occurrence of golden algae in the Gliwice Canal was not found during the last survey carried out as part of the intervention monitoring of CIEP on June 7” – explained the ministry in a communiqué.
