A dam was built on the Oued el Albid upstream of some lovely gorges and the huge 3 755ha reservoir that reflects the surrounding mountainous terrain. This impressive piece of engineering, 133m high and 285m long at the top, produces electricity and irrigates the Tadla Plains. The road affords great views of the winding, gently sloping banks and countless small islands. It eventually leads to Ouzoud Falls, then the gorges carved out by the Oued el Abid.
