Sebou River

The fourth one in Top 10 Longest Rivers in Morocco that Toplist would like to introduce to you is Sebou River. The Sebou River is located in northern Morocco. It is known as the Guigou River at its headwaters in the Middle Atlas Mountains. The river is 496 kilometers long and has an average flow of 137 m3/s, making it the largest river in North Africa by volume. It flows near Fes and empties into the Atlantic Ocean at Mehdya. Sebou is navigable for only 16 kilometers, all the way to Kenitra, Morocco's only river port. Its main tributaries are the Ouergha River, the Baht River, and the Inaouen River. The river irrigates Morocco's most fertile region, the Gharb.

In antiquity, Sebou was known as Sububus. Pliny the Elder describes it as "magnificus et navigabilis" (grand and navigable), flowing near the towns of Banasa (near Mechra Bel Ksiri) and Thamusida.

Despite the fact that there are few historical references to the Sebou being used for navigation after the Islamic conquest, its river mouth was an important harbor and shipyard during the Almohad period.

The Alaouite sultan Moulay Rashid built a bridge across the river near Fes in 1669–1670, which is still standing today.

During the precolonial period, the Sebou was famous for its Twait shad, which was highly prized by the people of Fez, but the shad became extinct on the Sebou due to pollution.

During the early years of the French protectorate, an expedition on the small steam boat Le Dantec successfully navigated the Sebou from Sidi Ali Ben Sliman to the city of Fez.
