Démantèlement d'un barrage en Europe

Du 5 au 11 juillet, nous célébrons à la fois le Big Jump 2021 (11 juillet) et la collecte de fonds de Dam Removal pour la suppression de barrages. Une semaine pour sensibiliser sur les dégâts des millliers de barrages présents sur nos rivières dans toute l’Europe.

Ne pensez-vous pas que nos rivières sont mal en point depuis trop longtemps? Libérons les!

Pourquoi est-il primordial d‘effacer les barrages et de retrouver des rivières courantes?

Parce-que les rivières d’Europe sont très mal en point, fragmentées par plus d’un million d’obstacles à l’écoulement et que tous ceux-ci causent des dommages, aussi bien les grands ouvrages que les petits. Ils dégradent l’ensemble de l‘écosystème, aussi bien l’écoulement naturel de l’eau que la circulation des poissons, mais aussi l’identité et l’héritage culturels des populations locales.

Et le point le plus important est que ces obstacles n’ont plus d’usage aujourd’hui! Alors, pourquoi pas les supprime?

The Liri river, which is mentioned by Dante, is particularly famous for being managed  by the Ancient Romans. Their architects planned and built a canal under the mountains that surrounded Lake Fucino  in order to empty it and direct its waters toward the lower altitudes of the Liri catchment area. Since then, the exploitation of the Liri river has continued for other purposes. For example, it has been used to produce energy, beginning with the Torlonia House and its first electrical powerplant. Now the natural habitats of the upper Liri are scattered with power plants and weirs that are making fish life harder, especially for the rarer species, such the barbel (Barbus fucini) and the Etruscan chub (Squalius lucumonis - IUCN Red List Categoy Endangered), or protected ones, such as the South European roach (Rutilus rubilio) and the Italian riffle dace (Telestes muticellus). Dismantling some specific weirs will open about 20 km of the river for freshwater wildlife. This will ensure  more extensive natural habitats for fish, increasing their chances of survival and, as consequence, supporting vital populations of their predators, such as the black-crowned night-heron (Nycticorax nycticorax) and the Eurasian otter (Lutra lutra), which is endangered in Italy. However, the otter could recolonize the Liri river over the next few years.

Good news for rivers! WWF Slovakia removes a dam thanks to everyone's participation!

The removal today of the largest barrier on the Hučava river, in Slovakia, has come true after a flash citizens' fundraising action last month of December, through WWF's FreeTheRiverToday.com platform. Next month the Big Jump 2021 Simultaneous Dam Removal Crowdfunding will sentence 6 more dams to be banished, freeing many rivers in different European countries at the same time.   The Hučava river can finally flow free thanks to today's removal of its only barrier. This success was achieved thanks to dozens of donors that participated through the crowdfunding platform FreeTheRiverToday.com led by WWF and coordinated with different partners in the Dam Removal Europe coalition. In the past years the platform has witnessed hundreds of citizens funding dam removals in 13 other river barriers across Europe, may of which are also already demolished.

The first human intervention into the river flow starts in Očová village. The river was straightened out and deepened, original meanders have disappeared, the river banks were built up to protect the surrounding buildings. Two barriers were built on the river, the first one directly in the village – where a fish pass is planned to be built, and the other, which is just being removed, under the village. After the intervention on both barriers, 25 km of the river will be freed.
“Removal of dams which are old and useless is the best way of freeing a river. It improves its ecological status and biodiversity, restores the function of the river landscape, including water retention, and thus contributes to the mitigation of climate crisis. Hučava dam removal is just a beginning. Together with other partners, we already finalise an evaluation of other river barriers suitable for removal," says Miroslava Plassmann, CEO of WWF Slovakia.
WWF Slovakia cooperates on monitoring and evaluating river barriers with the Slovak Water Management Enterprise and the State Nature Conservancy of the Slovak Republic. The list of barriers suitable for removal contained in the Water Plan of the Slovak Republic will be extended after WWF Slovakia finalises its work on reassessment of removal method.
