Sélune: the demolition of the Vezins dam on the way

It is a historic moment for Sélune! In recent days the cranes are at work on the left side of the dam and started the deconstruction of Vezins dam itself.

By the end of May the machines were present on site to dismantle the old hydroelectric power plant and make work to be transparent to floods. In this way in June three big openings (4X5meters each) were realized and the three bottom sluices open allowing passage of centennial floods.

In a few weeks another gear will come into action. Already installed at the foot of the dam this crane and 55 meters long articulated arm will dismount the central part of the dam.

Work are schedulde throughout the summer and until the fall.

The international media cover the Selune case : among others the international network of WWF, the BBC, AL Jazeera, La Vanguardia and Eldiario in Spain, Dennik N in Slovakia will report on the spot.

More about the project and the steps that led to this decision, see our dedicated page

 

New Poutès : the three sluices will be removed at the end of this summer

The work for the new Poutès in the upper part of the Allier basin (France) is ongoing. And we will soon have an important momentum in the history of the Poutès dam. Indeed, at the end of the summer, the three sluices, each 14x5m and 20 tons, will be removed from the structure.

Since the end of May, the reservoir is completely emptied, revealing the old bed of the Allier river.

The bottom sluice gate is fully open. The machines will soon invest the area. A platform that will remain until 2021 (expected end of works) will be installed in front of the dam to allow work on the structure. A crane will then take the sluice, put them on the platform, where they will be cut before joining a revaluation workshop. The reservoir will be refill during the winter 2019. The removal of a part of the dam itself will then continue during spring of 2020 after the smolts downstream migration.

See schedule for work until 2021, and the history of Poutès dam in our dedicated webpage

Reminder, the Poutès dam will be lowered by 10 meters (now it is 17m) and completely retrofit to facilitate fish migration and sediment transport.

France: Biggest dam removal in European history started

Sélune River, Normandy, France – In a historic moment for Europe’s rivers, the first, irreparable breach was made today in the 36 metre high Vezins Dam – kick-starting the biggest dam removal in Europe so far.

This landmark event is part of a long-term project to free the Sélune River, and bring salmon, eels and other wildlife back to the river and the famous bay of Mont-Saint-Michel – a UNESCO world heritage site and one of Europe’s prime tourist attractions.

Along the Sélune River in Normandy, the removal of two old, obsolete dams over the next two years – the Vezins and La Roche Qui Boit— will open up 90 km of river, improving water quality, allowing migratory salmon to return to their ancient spawning grounds and benefiting people and nature all along the river.

“The removal of the Vezins Dam signals a revolution in Europe’s attitude to its rivers: instead of building new dams, countries are rebuilding healthy rivers and bringing back biodiversity,” says Roberto Epple, president of European Rivers Network and 2018 Euronatur Award recipient. “Nature can recover remarkably quickly when dams are removed and I look forward to watching salmon swimming past Mont St Michel and spawning in the headwaters of the Sélune for the first time since my grandparents were young.”

Historically, the Sélune River was home to salmon that travelled from the river mouth, near Mont Saint Michel, upstream to mate and lay eggs. However, construction of these two dams stopped the salmon from migrating and this effectively stopped the recreational and commercial harvest of them as populations collapsed. The removal of these dams will help to bring more wildlife and biodiversity back to the river along with other recreational and touristic opportunities.

Artificial barriers (dams) are one of the biggest threats to river ecosystems, resulting in river fragmentation and loss of habitat connectivity. They stop the natural flow of sediments downstream and affect migratory fishes from travelling up- or downstream to complete their lifecycles. These impediments often lead to the decrease or decimation of native fish populations and can harbour other, non-native species in their adjacent impoundments. A new study in Naturerevealed just one-third of the world’s longest rivers remain free-flowing with river “fragmentation and flow regulation are the leading contributors to the loss of river connectivity.”

Globally, freshwater species populations have declined by 83% on average since 1970. The recently approved Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) reportspecifically recommends conserving and restoring river connectivity to boost freshwater biodiversity. As prescribed by the Water Framework Directive (WFD), each of Europe’s rivers must attain a ‘good’ ecological status and yet 40% of rivers fall short. Removal of old, obsolete dams is a viable option to help reach WFD goals, reconnect and restore rivers and allow fish populations and other wildlife to return and flourish. In fact, many countries in Europe are now removing dams as the economic, environmental and social benefits of doing so far outweigh the alternative of restoring the dam.

It is estimated that over 3,500 barriers have been removed across Europe including the biggest dam removal in Spain last year and an ongoing historical river restoration project in Estonia that will remove 8-10 dam and open up 3,300km of river basin. Moreover, European citizens are also donating funds to see these barriers go as a part of a larger dam removal crowdfunding campaign.

“There are tens of thousands of old, obsolete dams in Europe that can and should be removed,” says Arjan Berkhuysen, managing director of the World Fish Migration Foundation.  “We are hopeful that by removing not only big dams like this but also by removing small barriers through local efforts we can restore these important life sources.”

The unique project will measure the effects of dam removal with ten-years worth of environmental data.

The prefect of Lot-et-Garonne orders the Caussade dam removal

No less than 5 court decisions, favorable to FNE and SEPANSO Aquitaine, as to the illegality of the project, had not prevented the Chamber of Agriculture of Lot-et-Garonne to build a dike 300 meters long by 12 meters high on the Caussade stream in order to create an artificial lake of 920 000 m3 for about 20 farmers.

But on May 2, the state took a decree obliging the Chamber of Agriculture to destroy the dam within 3 months and to restore the site under 18 months: restore the riverbed, wetlands, destroyed habitats many protected species; put in place compensation measures proportionate to the impacts of illegal work …. The decree also specifies that the Chamber of Agriculture must record 1 million euros corresponding to the dam removal works, with a penalty of 500 € per day within 3 months if the reservoir has not disappeared.

In a territory where the lack of water is regular, FNE denounced a racket of water and a project that did not respond to the challenges of climate change and sharing the resource. In its court decision, the court also pointed out that this project is incompatible with the Water Framework Directive and the SDAGE (Master Plan for Water Development and Management) of the Adour-Garonne basin and acknowledged the lack of contribution of the project to the adaptation of agricultural productions to climate change “.

This is a victory for the NGOs, who will monitor the application of the decree and rely on the authorities to enforce the rules.

Large scale dam removal: “Selune Valley Revival”- International conference – FIRST CALL

European Rivers Network, the French Agency for Biodiversity, the national french Federation for Fishing, Dam Removal Europe  and the INRA announce the international conference on dam removal and renaturation of the Sélune river, from 24th to 26 September, 2019 in Brittany and Normandy (Mont Saint Michel).

The Sélune, coastal river, considered as the 3rd river of France in “Salmon potential”, now renaturing, will be at the heart of the conference and presented with different points of view (ecological, territory project, research program). This summer, the Vezins dam (36m high) will be removed making this project the biggest dam removal project in Europe. These huge works – which will be followed by the removal in 2021 of the La Roche-qui-boit dam (16m high), will improve the quality of the water into the bay of Mont St Michel and restore ecological continuity for more than 70 km of Selune river. It is an opportunity for the territory to create value with this river renaturated. The project has an important scientific monitoring program since more than 6 years (sociological, geomorphological and biological) allowing knowledge of the valley, helping the implementation and evaluation of the project.

3 days of conference will present a global vision of the policy of restoration of continuity in France and in Europe by highlighting the successes and the failures, the means implemented, the challenges and stakes to integrate and the research programs. Cases studies from Europe and US on dam removal and territorial projects compatible with a free flowing river will be shown.

Registration and practical info  : > www.ern.org/en/colloque-international-selune/

This event is part of the internationals seminars regularly organized by the Dam Removal Europe platform co-founded by ERN – the next event will take place on 22 and 23 May in Estonia – and give the chance in Europe, France and the Sélune Basin to share knowledge and experiences on dam removal and projects enable the re-appropriation of the river space.
