In Oulu, Finland, significant flooding took place in Ainolanpuisto, located in the city center, when water overflowed from the Oulujoki River. This flooding was attributed to a malfunction at the Merikoski power plant, which caused an uncontrolled discharge of water. In response to the situation, local police were deployed to the area to ensure safety and prevent public access to the flood zone.

Authorities utilized megaphones and barriers to cordon off the area, effectively managing the situation and ensuring that no one ventured into the flood-prone zones. The disturbance caused by the flooding lasted for nearly two hours on Sunday afternoon, but the situation was under control by around 4 PM. Although Ainolanpuisto and its nearby riverbanks were affected, the floodwaters did not spread beyond this immediate location, limiting damage and risk to the broader community.

The prompt response by emergency services and police underlines the importance of rapid action in managing natural disturbances, especially those caused by industrial incidents like the one at the Merikoski power plant. The situation highlights ongoing concerns regarding infrastructure safety, particularly around hydropower facilities that can have significant impacts on surrounding areas during malfunctions.
