Juine

The Juine is a French river, long. It is a left tributary of the river Essonne.
Its source is in Loiret, in the forest of Chambaudoin, less than 3 km south-west from Autruy-sur-Juine. Its name originates in the hamlet of Juines which it runs alongside before re-entering the Essonne department, in which it runs through several communes:
Méréville, Saint-Cyr-la-Rivière, Ormoy-la-Rivière, Étampes, Étréchy, Chamarande, Janville-sur-Juine, Bouray-sur-Juine, Lardy.
It also runs through the parks of several châteaux and once served several now-abandoned mills. From the 15th to the 18th century, it combined with the Essonne and Seine rivers to form a navigable waterway for flat-bottomed boats carrying wheat from Beauce towards Paris. It joins the river Essonne between Itteville and Vert-le-Petit, near Ballancourt-sur-Essonne.
