Barrage Oued Ermal. 02/02/12; Zaghouan; 620 ha; 36°20'56"N 010°20'55'E. A dam and reservoir that constitutes a vital area for several waterfowl at various critical stages of their life cycle. It is a nesting place for such waterbirds as Cattle Egret, Spoonbill, Eurasian Coot, Shoveler Ducks, Plover, Gadwall, Avocet, Black-winged Stilt, Northern Lapwing, Common Snipe, Marbled Duck, Marsh Harrier, Kingfisher, Water Pipit, Skylark, and Chiffchaff. The vegetation surrounding the site is dominated by Eucalyptus sp. The dam has a significant hydrological value as a source of irrigation for a large area immediately downstream in the plains of Bouficha. The area has important historical value due to the presence of the Roman monument "Temple des eaux". It is threatened by the rearing of animals, which increases soil erosion and causes the destruction of the natural vegetation as well as a decrease in the quantity of water and potentially the death of fish species. Ramsar Site no. 2014. Most recent RIS information: 2011.
