Lagoon of Sariñena Nature · Sariñena, Los Monegros, Huesca An endorheic lagoon at 281 metres above sea level between the Flumen and Alcanadre rivers, in the municipal area of Sariñena (Huesca), covering 206 hectares and with a depth ranging from 50 centimetres in the south to 2.35 metres in the north. Formerly known as the Chapazal, it was a shallow, temporary saline lagoon until, with the arrival of irrigation, it became a drain for surplus irrigation water and lost its salinity, leading to the construction of a drainage canal to regulate its level. The vegetation on its shores and the presence of fish made it a draw for waterfowl, especially ducks, which led to its being declared a Wildlife Refuge in 1995 and a Special Protection Area for Birds in 2001.
