Barrage de Sidi Saad. 02/02/12; Kairouan; 8,650 ha; 35°22'N 009°40'E. A dam and reservoir that was created in 1981 to fight against floods of the river Zeroud and ensures a supply of potable water in the region of Kairouan. It is a breeding zone for several fish species and includes introduced freshwater fish like the carp Ctenopharingodron sp., zander Sander lucioperca, common roach Rutilus rutilus, rudd Scardinius erythrophtalmus and catfish Silurus glanis, as well as the introduced marine Mullet, and occasionally the semi-aquatic turtle Mauremys leprosa is observed on the site. It supports several species of waterbirds including herons, the coot Fulica atra, and Great Crested Grebe. The watershed is located in the Mediterranean Biome-North Africa and characterized by high relief hosting some tufted reeds and benthic fauna, dominated by phanerogram plants like the sago pondweed Potamogeton pectinatus. The site is state-owned but provides livelihoods through fishing and irrigated agriculture to people in the region, though over-exploitation of these resources is seen as a potential threat.
