The Draa is Morocco's longest river. It is formed by the confluence of the Dadès River and Imini River. It flows from the High Atlas mountains south-(east)ward to Tagounit and from Tagounit mostly westwards to the Atlantic Ocean somewhat north of Tan-Tan. Most of the year the part of the Draa after Tagounit falls dry.
The water from the Draa is used to irrigate palm groves and small horticulture along the river. The inhabitants of the Draa are called Drawa (an exonym), the most famous Drawi (singular of Drawa) undoubtedly being mawlay Mohammed ash-Sheikh. Outside of the Draa region this name is mostly used to refer to the dark skinned people of Draa which make up the largest portion of its inhabitants.
