Senegal River

geography Maturity 7-9 Next article →

The Senegal River is a major waterway in West Africa. It plays a vital role in the region's geography and history. Much of its length forms a border between Senegal and Mauritania. The name comes from the Serer people. It combines the term "Seen," meaning a supreme deity, with "O Gal," meaning a body of water.

The river begins in Guinea with two headwaters. These are the Semefé and Bafing rivers. They flow together at Bafoulabé in Mali. From there, the river moves west and then north. It passes through the Talari Gorges and over the Gouina Falls.

The river grows larger as it picks up several tributaries. These include the Falémé, Karakoro, and Gorgol rivers. Near Kaédi, the river divides into two distinct branches. The left branch is called the Doué. It runs parallel to the main river until they rejoin near Podor. A long strip of land called Île á Morfil sits between these branches.

Managing such a large system requires international cooperation. In 1972, Mali, Mauritania, and Senegal founded the Organisation pour la mise en valeur du fleuve Sénégal, or OMVS. This group manages the river basin for all members. Guinea joined the organization in 2005.

The OMVS is studying a way to make the river navigable. They want to create a channel between Ambidédi in Mali and Saint-Louis. This channel would be 300 meters wide. It would provide landlocked Mali with a direct route to the Atlantic Ocean.

Human engineering has significantly changed the river's flow. There are two large dams along its course. The Manantali Dam is located in Mali. The Maka-Diama Dam sits on the border of Mauritania and Senegal. This dam prevents salt water from moving too far upstream. Between these two dams is the Félou Hydroelectric Plant. The original plant was built in 1927. It was replaced by a new station in 2014. In 2013, work began on the Gouina Hydroelectric Plant at Gouina Falls.

The river has a very long history of human interest. Early Mediterranean civilizations were aware of its existence. The writer Pliny the Elder called it "Bambotus." Claudius Ptolemy referred to it as "Nias."

In the Middle Ages, Arab geographers provided early descriptions. Al-Masudi, al-Bakri, and al-Idrisi all wrote about the river. Some geographers believed it was a "Western Nile." They thought it might connect to the Niger River or the Nile in Egypt.

Because the river reached the gold-rich Ghana and Mali Empires, it earned a famous nickname. Traders called it the "River of Gold." This reputation reached European merchants in Morocco. Some maps from the 14th century show this river.

These maps often depicted a great river island. This island was sometimes called "Wangara" or "Palolus." Scholars believe this might actually be the Bambuk-Buré goldfield district. This area is surrounded by several rivers, including the Senegal and the Falémé.

The river eventually meets the Atlantic Ocean. It flows around an island near the city of Saint-Louis.

A thin strip of sand called the Langue de Barbarie separates the river from the sea. The river's ecosystem is part of the Senegal-Gambia Catchments. This ecoregion combines the Senegal and Gambia River basins. The species richness in this area is moderately high. However, only three species of frogs and one fish are endemic to this specific region. This means they are found nowhere else on Earth.
