A long-term programme of hydrological and ecological restoration has been conducted on the French Rhone River since 1998. Its main components are i the increase of the minimum flow in the river sections bypassed by an hydro-power plant, ii the direct reconnection of cut-off channels to the river, iii the dredging of isolated pools within the channels. The presentation highlights a selection of key findings from the pre- and post-restoration monitoring of fish and macroinvertebrate assemblages in the River and its floodplain, carried out in four different sectors since 1995.
