Site description The site is the second-largest man-made reservoir in Morocco, on the Oued Oum Er-Ribi’a, located approximately 50 km south of Settat. Lying at an altitude of 265 m, the reservoir is around 30 km long, has a surface area of 14,000 ha, and a maximum depth of 60 m. Situated in a hilly valley, the reservoir’s border is heavily indented and there are many islets, some of which only emerge when the water-level is low. The reservoir’s shores are mainly rocky, and are partly wooded with Eucalyptus and Acacia species. Aquatic plants such as algae and Potamogeton grow in profusion along a 10–50-m-wide strip around the reservoir’s edge. When the water-level drops, exposed mudbanks and the drying aquatic plants provide extensive feeding habitat for waterbirds. Average annual precipitation is 200 mm.
