Oir

L'Oir est une rivière de la Manche.

C'est un affluent de la Sélune dans laquelle elle se jette à Ducey, près du château du Val-d'Oir.

Long de 21 km, l'Oir prend sa source à Reffuveille et passe à Montigny, La Mancellière, Montgothier (dans Isigny-le-Buat), Marcilly, Les Chéris (dans Ducey-Les Chéris).

Il a pour principal affluent le ruisseau du Pont-L'Evesque (7 km).

Une station de contrôle des poissons migrateurs est installée depuis 1983 sur le canal d’entrée du moulin de Cerisel.
