Europe Removes Record 603 Dams, Freeing 2,300 Miles of Rivers

Rivers across Europe are flowing freely again after countries removed a record number of dams blocking their natural paths.

More than 603 river barriers came down across Europe in 2025, reconnecting 2,300 miles of waterways and reopening ancient migration routes for fish. The surge represents an 11% jump from 2024 and marks the biggest year yet for dam removal on the continent.

Sweden led the charge with 173 removals, followed by Finland with 143 and Spain with 109. Iceland and Macedonia celebrated their first dam removals ever, joining a growing movement to restore Europe's rivers to health.

The results are already visible. Along Wales' River Lee, sea lamprey nests have multiplied since crews removed Eribstock Weir. These ancient fish, which have survived since dinosaur times, are finally finding safe places to spawn again.

"Seeing these nests is genuinely exciting," said Joel Rees-Jones, who led the Welsh project. "By reconnecting habitats and removing barriers like Erbistock Weir, we're giving iconic species such as lamprey and Atlantic salmon a fighting chance to thrive."

Dam Removal Europe, the environmental group tracking the progress, says the removals improve more than just fish populations. Free-flowing rivers filter water better, reduce flood risks, and create healthier ecosystems for countless species.

The Ripple Effect

The dam removal movement is picking up speed across continents. As more communities witness the revival of their local rivers, neighboring regions are taking notice and launching their own removal projects.

The work also creates jobs for engineers, ecologists, and construction crews while saving governments money on maintaining outdated structures. Many of the removed dams no longer serve their original purposes, making them expensive relics that do more harm than good.

Still, the job is far from done. More than 150,000 obsolete barriers continue to choke European rivers, fragmenting habitats and blocking fish from reaching spawning grounds.

But momentum is building, and nature is proving remarkably resilient when given the chance to recover.
