Mayenne

The Mayenne ) is a 202.3 km long river in western France principally located in the French region of Pays de la Loire. Together with the river Sarthe and its tributary the Loir it forms the Maine, which is a tributary to the Loire.Its source is in the department of Orne near the commune of Lalacelle, between Pré-en-Pail and Alençon. The source is in the foothills of Mont des Avaloirs at an altitude of 961 feet ; from there the river runs from east to west until it reaches Sept-Forges, at which point it turns to the south. After being joined by the Oudon, the Mayenne forms a confluence with the Sarthe north of Angers. The confluence of these two rivers is called the Maine, which is the local pronunciation of Mayenne. The waters of the Maine then empty into the Loire south of Angers.
