River revolution in Europe as France launches largest dam removal project on the continent
Eight years after the idea was initially discussed, the French government agreed last week to remove the 35 metre-high Vezins and 15 metre-high ‘La Roche qui boit’ dams from the Selune river in Normandy in 2018.
With France leading the way, countries from Spain to Finland have taken down many small and obsolete dams in recent years, but freeing up the Selune represents the largest dam removal project so far in Europe – and a major step towards bringing life back to the river, including wild salmon and eel whose migrations have been blocked by the dams for decades.
“The dismantling of these ancient dams after almost 100 years of hydropower generation is a landmark in Europe’s attitudes to its rivers and energy production,” said Roberto Epple, Founder President of the European Rivers Network (ERN). “Removing these obstacles will help rewild the entire 90 kms of the Sélune, allowing fish to migrate and sediment to flow and rapidly boosting the river’s biodiversity.”
Fragmenting rivers with dams, barrages and other infrastructure has played a major role in the catastrophic loss of fish and other freshwater species across the continent. Removing these concrete obstacles will help to reverse this trend and provide other benefits to communities along Europe’s riverbanks, including income from the anglers who will follow the fish back to the rivers.
Indeed, fishing associations have long worked with French environmentalists to bring down the two Selune dams as part of the ‘Friends of the Selune’ coalition (see the attachment for a list of members).
“Choosing to remove these dams will help to revolutionise Europe's approach to rivers: instead of erecting new dams, it is time to start dismantling dams and bringing life back to our rivers,” said Bart Geenen, Head of Freshwater, WWF-Netherlands. “Studies clearly show that dam removal is by far the most cost-effective way to restore rivers. Living rivers will boost biodiversity and provide new and exciting opportunities for local people.”
The project is aligned with France’s commitment to the conservation of its remaining wild salmon and eel populations and with the requirements of the EU Water Framework Directive.
“Signalling the end of the road for these dams is cause for celebration, but we still need a clear and binding timetable from the government,” said Epple, who is also one of the driving forces behind Dam Removal Europe. “The authorities must also involve local communities in plans to develop sustainable tourism in the valley.
