Turns out, some things are better off demolished. Europe just had a banner year for tearing down obsolete river barriers, clearing a record 603 dams, weirs, and culverts in 2025. That satisfying number reconnected more than 3,740 kilometers (that's 2,324 miles) of rivers across the continent.
Think of it as giving a whole lot of aquatic life a much-needed breath of fresh water. And giving rivers back their mojo.
A Big Win in North Macedonia
One of the bigger demolition parties happened in Kumanovo, North Macedonia. For over 70 years, a concrete monster — 53 meters (174 feet) long and 30 meters (98 feet) wide — had been squatting in the Pčinja River. It wasn't just an eyesore; it was a total roadblock, stopping water and fish from moving freely for about 70 kilometers (44 miles) upstream.

So, in late 2025, with a little help from the environmental group Eko-svest, that barrier came down. It was North Macedonia's first large-scale dam removal, which is a pretty good way to kick off a trend.
Chris Baker, director of Wetlands International Europe (WIE), calls barrier removal "one of the biggest ecological 'easy wins' available today." Which, if you think about it, is a pretty rare thing to hear about any environmental effort. But he's got a point: these old barriers are often doing more harm than good, just sitting there, literally blocking progress.
Europe's rivers are currently fragmented by a staggering 1.2 million barriers. And here's the kicker: over 150,000 of those are considered obsolete. Since 2020, almost 2,300 dams have been removed, mostly in Sweden, Finland, and Spain. Even Iceland got in on the action in 2025, taking out an old, unused hydroelectric dam. Because sometimes, the best way forward is to simply clear the path.
