The Idriss I Dam, also known as the Idriss the First Dam, is a gravity dam on the Inaouen River, a tributary of the Sebou River. The dam is situated in the Gharb Basin and is located 27 km (17 mi) northeast of Fes in Taounate Province, Morocco. The dam serves to provide irrigation for 72,300 ha (178,657 acres) of land and its power plant generates 66 GWh of electricity annually. It is named after Idriss I[2] It has come under criticism since it failed to deliver irrigation to the projected number of acres and it has also denied water use to historical downstream agricultural and residential users.[3]

Environmental issues[edit]

A number of water pollutants enter the Sebou River and its tributaries, notably including pesticides and fertilisers from agricultural runoff and untreated sewage from towns along the river.[4] In the upper parts of the watershed within the Middle Atlas is the prehistoric range of the endangered primate Barbary macaque, which animal prehistorically had a much larger range in North Africa.[5]
