The Ulldecona Dam (Catalan: Embassament d'Ulldecona) (Spanish: Embalse de Ulldecona) is a gravity dam located in the Tinença de Benifassà and the Ports de Tortosa-Beseit mountains, within the La Pobla de Benifassà municipal limits, Valencian Community, Spain.[1]
The dam was built in 1967 and was financed by farmers from the town of Ulldecona, hence its name.
