The Vire is a river in France that runs in the Normandy region . It rises on the municipal boundary of Chaulieu and le-Petit Truttemer- generally drained the north to northwest, reaching north of Saint-Lô the Regional Nature Park Marais du Cotentin et du Bessin and flows after 128 kilometers north of Isigny-sur-Mer on the municipal boundary of Les Veys and Osmanville , in an estuary in the English Channel . On its way, the Vire crosses the Calvados and Manche departments .

Hydrology and water quality
The mostly brownish water of the Vire is indicated by Lumina Tech as slightly alkaline with a pH value of 8.31. The water is relatively cloudy, with a Secchi lens a depth of view of 12 cm was determined.
Similar to the larger Orne river , the catchment area of the Vire is also subject to a maritime climate. This is expressed by low water levels. The flow rate in August is only 2.34 m³ / s, in contrast to the annual average of 12.6 m³ / s. However, this does not prevent the occasional occurrence of floods. Occasionally catastrophic floods occur, such as in 1843, when numerous thunderstorms caused the river in Saint-Lô to overflow, flooding lower-lying areas.

Just below Saint-Fromond , the former canal Canal de Vire et Taute branches off to the left , which connects the rivers Vire and Taute .
