Créquoise
The river Créquoise is one of the small streams that flow from the plateau of the southern Boulonnais and Picardy, into the Canche.
The river rises at Créquy and passes by Torcy, Lebiez, Hesmond, Offin, Loison-sur-Créquoise and joins the Canche at Beaurainville.
Three small tributaries join the Créquoise, the Fosse du Corval, L'Embrienne and le Surgeon
