Al Massira Dam
The 928th tallest dam in the world
The Al Massira Dam is a buttress dam located 70 kilometres (43 mi) south of Settat on the Oum Er-Rbia River in Settat Province, Morocco. Completed in 1979, the dam provides water for the irrigation of over 100,000 hectares (250, 000 acres) of farmland in the Doukkala region. The dam's hydroelectric power plant also generates 221 gigawatt-hours (800 TJ) on average annually. The power station was commissioned in 1980. Just north of the dam is a rip rap saddle dam that supports water elevation in the reservoir.
