River Overview
Geographic Identity
The Doubs is a significant river flowing through far eastern France and western Switzerland. It is characterized by its substantial length and its role as a left-bank tributary of the Saône River.
Key Dimensions
With a total length of 453 kilometers (281 miles), the Doubs drains a basin area of approximately 7,500 square kilometers (2,900 square miles). Its average discharge rate is measured at 176 cubic meters per second (6,200 cubic feet per second).
Origin and Confluence
The river originates in the Jura Mountains near Mouthe, France, at an elevation of 946 meters (3,104 feet). Its course concludes at Verdun-sur-le-Doubs, where it merges with the Saône River at an elevation of about 175 meters (574 feet).
Native Name and Countries
Known natively in Arpitan as Dubs, the river traverses two nations: France and Switzerland. Its course includes segments that form part of the international border.
The River's Course
Trajectory and Borders
Emerging from its source in Mouthe, the Doubs initially flows northeast. It then follows a path that borders and briefly enters Switzerland for approximately 40 kilometers before turning west and then southwest. This intricate path is influenced by the geological structures of the Jura Mountains.
Swiss Cantons and French Departments
The river's journey takes it through or along the borders of the Swiss cantons of Jura and Neuchâtel. In France, it flows through the departments of Doubs, Jura, and Saône-et-Loire.
Settlements Along the Banks
Significant settlements are situated along the Doubs' course. Notable cities include Pontarlier and Besançon in France, and Saint-Ursanne in Switzerland. The river eventually empties into the Saône near Verdun-sur-le-Doubs.
Unique River Shape
The river's path has been described as resembling the silhouette of a terrier sitting upright, leaning to its right. The northernmost extent into Switzerland forms a distinct "ear" shape near Saint-Ursanne.
Distinctive Features
Waterfalls and Lakes
The Doubs is notable for its scenic waterfalls and lakes. The impressive Saut du Doubs waterfall is situated on the French-Swiss border. Nearby, the river forms the Lac des Brenets, a 4-kilometer long lake created by a natural landslide.
Hydrological Formations
Beyond the Saut du Doubs and Lac des Brenets, the river is associated with several other significant lakes, including Lac de Saint-Point, Lac de Moron, and Lac de Biaufond. These formations contribute to the river's varied landscape.
Tributaries
The Doubs receives water from several tributaries. Key left-bank tributaries include the Loue and Dessoubre rivers, while the Allan is a notable right-bank tributary. These contribute to the river's overall flow and basin characteristics.
Hydrological Dynamics
Seasonal Variability
The Doubs exhibits significant seasonal variation in its flow rate. The period from September to May is typically characterized by higher water levels, influenced by substantial rainfall and the melting of snow from the Jura Mountains.
Discharge Fluctuations
The river's discharge can fluctuate dramatically. At its mouth, flow rates can range from as low as 20 cubic meters per second during dry periods to over 1,000 cubic meters per second during flood events.
Historical Flooding
Major flood events have impacted communities along the Doubs. In Besançon, significant floods were recorded in 1852, 1896, and 1910, illustrating the river's potential for powerful seasonal surges.
Hydroelectric Potential
Harnessing River Power
The Doubs' characteristics as a mountain river with considerable discharge have made it a valuable resource for hydroelectric power generation. Several facilities utilize its flow to produce electricity.
Key Hydroelectric Structures
Among the notable hydroelectric installations are the Dam of Châtelot, standing 74 meters tall, and the Dam of Refrain, measuring 66.5 meters in height. These structures play a role in managing the river's flow and generating energy.
Cultural Resonance
Literary Mentions
The Doubs River holds a place in literary history, notably being mentioned sixteen times within Stendhal's renowned novel, The Red and the Black (Le rouge et le noir). This highlights its presence in the cultural landscape of the regions it flows through.
