L'étang de Waligny (The Waligny pond)

The Walligny pond is part of the basin in the catchment area of the river Canche which has a large number of alluvial wet zones. The site is disconnected from the river Canche which is now well canalised. This site plays the role of retention basin thus limiting flooding during heavy rainfall. This site was modified by man for a long time, but today it has regained its wild state, which is what makes it unique.
