Site description Lac Oubeïra lies about 60 km east of the city of Annaba and 15 km west of the Tunisian border, in the north-east of the country. It forms part of the complex of wetlands included within the Parc National d’El Kala and lies c.10 km west of Lac Tonga (site DZ002). The site lies at 25 m altitude and consists of a shallow (maximum depth 3 m), permanent, eutrophic, freshwater lake surrounded on the three sides by cork oak woodland and maquis. The lake lies c.5 km from the Mediterranean Sea and it is bounded to the north by a major sand-dune system. The lake is replenished in winter when flood water from the Oued El Kebir flows across intervening marshland and in to the lake via a channel in the south-east corner. Sluices have been constructed on the channel to retain water in the lake when the flood levels drop. The lake can be slightly saline, especially in summer, as indicated by the presence of zooplankton typical of slightly saline conditions. There is a small area of Phragmites australis and Scirpus lacustris on the western shore and dense submerged aquatic vegetation dominated by Myriophyllum and Ceratophyllum spp. There are extensive beds of Potamogeton pectinatus, and Trapa natans (rare in Algeria) is present. The lake supports a commercial fishery based on the exploitation of indigenous species of Mugil, Anguilla and Alosa; these, together with Atherina sp. and Gambusia affinis gain entry to the lake during winter floods. The shallow edges and the shores of the lake are grazed, maintaining a grassland strip clear of trees around the water’s edge. There is some hunting, but this is less intensive than on Lac Tonga (site DZ002).
