Site description The site lies about 90 km south of the town of Blida (south of Alger), in the Hauts Plateaux mountain range, on the southern edge of the Massif de l’Ouarsenis. It is the largest artificial impoundment on the Hauts Plateaux and lies close to the main N1 road, which leads south from Blida to Djelfa. The site consists of an open water surface in excess of 1,000 ha (when the lake is full) and extensive marshland to the south, surrounding the various oueds that flow into the lake. The lake is replenished by autumn and winter rainfall and water-levels vary greatly through the year as a result of evaporation and water flow out of the lake, with lowest levels usually occurring just before the rains in autumn. Vegetation in the permanent marshland includes lush areas of Phragmites sp. and Typha sp.
