In 2025, European crews dismantled 603 river barriers across 21 countries—the highest number ever recorded—marking the fifth consecutive year of growth in river restoration efforts that revive fish migration routes and improve river ecosystems.
- 603 barriers removed, up 11% from 2024
- 21 countries involved, including Iceland and North Macedonia for the first time
- Over 3,740 km of river habitat reconnected
What happened
In 2025, river restoration projects in Europe surged to a new record with 603 water barriers removed, surpassing the previous year's total by 11%. This continues a strong upward trend over the past five years, growing from about 100 removals per year just six years ago. Most dismantled barriers were small, outdated structures like culverts and weirs, largely abandoned or no longer serving their original purposes.
Leading the effort, Sweden removed the most barriers, many from historic logging operations, while Finland and Spain also contributed significantly to reconnecting rivers. Notable projects included the removal of a wartime concrete barrier in North Macedonia reopening habitat for unique fish species and Iceland’s first dam removal restoring habitat for sea trout and Atlantic salmon.
Why it feels good
Removing obstructions from rivers supports vital ecological functions by allowing fish to migrate freely and sediment to flow naturally, which are crucial for healthy aquatic habitats. Freshwater species have suffered from fragmentation caused by barriers, with over 40% threatened with extinction in Europe. Restoration efforts like these directly contribute to reversing those declines.
The scale of progress—thousands of kilometers of river networks reopened—represents one of the largest and most achievable conservation wins in Europe today. Governments and nature groups widely support barrier removal projects because they improve biodiversity while often being faster and less costly than larger infrastructure changes.
What to enjoy or watch next
While this record-breaking year signals great momentum, Europe still faces a long road ahead with an estimated 1.2 million water barriers remaining, many obsolete but yet to be removed. Continued commitment to dismantling outdated structures will amplify benefits for freshwater ecosystems and species survival.
Upcoming projects to watch include further removals in Southern Europe and expanding efforts in new countries embarking on river restoration. The growing network of restored waters offers exciting opportunities for nature lovers, anglers, and communities to engage with revitalized rivers supporting wildlife and clean water.
