Open Rivers : Quatri\u00e8me seuil effac\u00e9 sur la Tardoire<\/h3>\n

A Ch\u00e9ronnac (87), sur le site du Grand Moulin de Peyrassoulat, le dernier seuil a \u00e9t\u00e9 effac\u00e9 sur la Tardoire. L’ensemble des travaux sur les 4 sites a permis la r\u00e9ouverture de plus de\u00a0 20 km de rivi\u00e8res.<\/p>\n

Une particularit\u00e9 sur le seuil de grand moulin de Peyrassoulat, la r\u00e9alisation de fouilles arch\u00e9ologiques pr\u00e9ventives. Elles ont pour but de d\u00e9celer des objets retra\u00e7ant une activit\u00e9 humaine historique notamment d\u00fb \u00e0 la pr\u00e9sence d’une forge trois cent m\u00e8tres en amont. Ces activit\u00e9s m\u00e9tallurgiques et meuni\u00e8res atteignent leur apog\u00e9e au XVIIIe si\u00e8cle gr\u00e2ce \u00e0 la force motrice de l\u2019eau.<\/p>\n

Le seuil de Peyrassoulat pr\u00e9sentait une br\u00e8che de plus de 20 m ou l\u2019ensemble du parement du mur sud s\u2019\u00e9tait \u00e9ventr\u00e9. L\u2019eau en exc\u00e9dent dans la retenue passait par surverse sur le mur, ce qui \u00e0 la longue apr\u00e8s abandon d\u2019usage eu pour effet de le d\u00e9grader.<\/p>\n

Les travaux consistaient \u00e0 r\u00e9duire \u00e0 la hauteur de chute pour la ramener \u00e0 moins de 20 cm pour \u00eatre conforme \u00e0 l\u2019objectif de continuit\u00e9 \u00e9cologique. Durant 16 jours, l\u2019entreprise Tallet a \u0153uvr\u00e9 de concert avec l\u2019op\u00e9rateur EVEHA. Une bonne coordination des op\u00e9rations a permis avec efficacit\u00e9 la suppression de l\u2019obstacle dans les d\u00e9lais.<\/p>\n

Ce projet de restauration de la Tardoire est r\u00e9alis\u00e9 avec le soutien financier du programme Open Rivers, avec ma\u00eetrise d\u2019ouvrage du SYMBA et en partenariat avec ERN. Plus d\u2019infos\u00a0<\/a><\/p>\n<\/div><\/section>
