The Loue is a river of eastern France, a left tributary of the Doubs, which it joins downstream of Dole. Its source is a karstic spring in the Jura mountains near Ouhans, which at least partly receives its water from the Doubs. This connection with the Doubs was only discovered in 1901 when a spillage from the Pernod factory into the Doubs was transmitted into the Loue .The Loue flows through the following départements and towns:Doubs: Ornans, QuingeyJura: Montbarrey↑
