This saline enclosed (endorheic) lagoon with associated islands is fed by groundwater, rainwater and surface water, and regularly dries out. Vegetation includes submerged aquatic plants and fringing reedbeds. It is an important area for endemic and threatened animals including many waterbirds such as the white-headed duck (Oxyura leucocephala) and the marbled duck (Marmaronetta angustirostris). The surrounding area is used for agriculture, including the cultivation of vines, olives and arable crops. There has been a decline in rainfall in the area, and the discharge of treated wastewater into the lagoon to maintain water levels has increased, leading to a decrease in salinity and increased nutrient input. In 2021 the boundaries were delineated more accurately, increasing the total area by 30 hectares.
