River

Weather…

The Ouergha River is a major tributary of the Sebou River in northern Morocco, originating in the central Rif Mountains. Stretching approximately 250 kilometers, the river system is essential for the hydrological balance and agricultural productivity of the Gharb region. The river is home to the Al-Wahda Dam, commissioned in 1997, which stands as Morocco's largest dam and the second largest in Africa by reservoir capacity. This massive infrastructure project provides flood control for the fertile Gharb plains, irrigates over 100,000 hectares of farmland, and generates significant hydroelectric power. Geologically, the catchment area is characterized by fragile marl soils, leading to high erosion rates and sedimentation challenges within the reservoir. Historically, the Ouergha Valley was a strategic front in 1925 during the Rif War, marking the limit of French colonial influence against the northern tribal resistance. Today, the area is recognized for its ecological value, providing a sanctuary for diverse fish species and migratory birds.
