Laguna de la Nava

The artificial lagoon spans 326 hectares at 730 meters elevation, providing essential habitats for migratory birds throughout their seasonal movements.

Originally covering 2,000 hectares, the lake underwent drainage in the late 20th century until restoration efforts began in 1990 to reestablish its functions.

Scientists conduct ornithological research at the lagoon, documenting over 222 bird species, representing 41 percent of all Spanish bird varieties.

Water levels in the lagoon are regulated artificially through the Canal de Castilla, maintaining an average depth of 40 centimeters from autumn until summer.

The site ranks as Spain's third most important wintering area for greylag geese, hosting between 10,000 and 12,000 specimens during cold months.
