Which 1,100 km river is Morocco's longest?

The Draa River is Morocco’s longest river, measuring about 1,100 kilometres. Its Arabic and Amazigh name is also written Drâa, Dra or Oued Drâa.

The river system forms in the High Atlas from the confluence of headwaters including the Dadès and Imini rivers. It flows southeast toward Tagounite, then bends west across southern Morocco before reaching the Atlantic coast north of Tan-Tan. Much of its valley is a chain of oasis settlements, where irrigation supports date palms and other crops.

The Draa is not a continuously flowing river along its entire course. Downstream of Tagounite, especially in the arid lower section, the channel is dry for much of the year. The El Mansour Eddahbi Dam, built in 1971 near Ouarzazate, helps regulate water and supply the region. That seasonal dryness can cause confusion, but it does not change the river system’s recognised total length or its status as Morocco’s longest.
