Doué River (French: Rivière Doué) is a left branch of the Senegal River in Senegal roughly between the cities of Kaédi and Podor. The Doué is about 68 kilometers long, and it runs parallel to the Senegal River on its southern side. The long land strip between the branches is called Morfil.
The Ndioum Bridge spans the Doué River to connect the town of Ndioum to Morphil Island. Prior to the bridge being built, people drowned frequently due to canoes and ferries being capsized.
The Senegal River (Serer: "Seen O Gal" or "Senegal" - compound of the Serer term "Seen" or "Sene" or "Sen" (from Roog Seen, Supreme Deity in Serer religion) and "O Gal" (meaning "body of water")); Wolof: Dexug Senegaal, Arabic: نهر السنغال, romanized: Nahr as-Siniġāl, Hassaniyya pronunciation: [nahrˤ əs.säjnigaːl], French: Fleuve Sénégal) is a 1086-kilometre-long (675 mi) river in West Africa; much of its length marks part of the border between Senegal and Mauritania. It has a drainage basin of 270000 km (100000 sq mi), a mean flow of 680 m/s (24,000 cu ft/s), and an annual discharge of 21.5 km (5.2 cu mi). Important tributaries are the Falémé River, Karakoro River, and the Gorgol River. The river divides into two branches once it passes Kaédi. The left branch, called the Doué, runs parallel to the main river to the north. After 200 km (120 mi) the two branches rejoin a few kilometers downstream of Podor.
In 1972 Mali, Mauritania and Senegal founded the Organisation pour la mise en valeur du fleuve Sénégal (OMVS) to manage the river basin. Guinea joined in 2005. As of 2012, only very limited use was made of the river for the transportation of goods and passengers. The OMVS have looked at the feasibility of creating a navigable channel 55 m (180 ft) in width between the small town of Ambidédi in Mali and Saint-Louis, a distance of 905 km (562 mi). It would give landlocked Mali a direct route to the Atlantic Ocean.
