Europe dismantles record 602 river barriers to restore waterways and wildlife

Throughout 2025, European nations removed a record-breaking 602 river barriers, including dams, weirs, and locks, to restore natural water flow.

These removals are part of a continent-wide effort to reconnect 15,500 miles of rivers and help migratory fish species like salmon reach their spawning grounds. Many of the dismantled structures were obsolete or crumbling, meaning they no longer served their original agricultural or industrial purposes and posed safety risks to nearby towns. Restoring these waterways improves water quality and biodiversity by allowing natural sediment to move and creating healthier habitats for local plants and animals.

Environmental groups expect removal rates to accelerate as the European Union works toward its 2030 biodiversity targets.
