The Al Massira Dam is a gravity dam located 70 km (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 ha (247,105 acres) of farmland in the Doukkala region. The dam's hydroelectric power plant also generates 221 GWh on average annually. The power station was commissioned in 1980. Just to the north of the dam is a rip rap saddle dam to support water elevation in the reservoir.[2] The dam's reservoir and wetlands were designated as a Ramsar site in 2005.[3]
