The complete renaturation of the Reynaud site, a former industrial site located on 2 rivers: the Dronne and the Chalaure, upstream of their confluence. This site includes a weir (a crossing structure located in the minor bed of the Dronne), a former hydroelectric plant, abandoned buildings and several riverside parcels with a total area of about 9 ha (afforestation, grasslands, islands). 
On the scale of the Dordogne basin, this site presents major ecological challenges. The restoration aims to create a space of freedom for the river, to allow it to regain its natural river dynamics and to have a flood expansion zone.
