Ulldecona Dam

Ulldecona Dam, reservoir in Spain

The Ulldecona Dam is a water reservoir in La Pobla de Benifassà where four small rivers converge: the Sénia, Teulatí, Tenalla, and Verd. The dam itself is a concrete structure rising about 54 meters tall and spanning roughly 180 meters across, with the water surface covering more than 800 hectares.

Construction of the reservoir began in the 1950s after farmers had formally requested an irrigation facility as early as 1907. The project started in 1951 and was completed in the 1960s to supply water for agriculture in the region.

The reservoir was built through the cooperation of local farmers in the 1960s who pooled money and labor to create this shared resource. This collective effort remains part of the community identity, showing how the people of the region work together to manage water for their agricultural life.

The area is quiet and easily accessible from La Pobla de Benifassà via a nearby road. Walking paths around the reservoir are open for visitors, and there are spots suitable for picnics and peaceful time in nature.

During dry periods, the water level drops noticeably, showing how dependent the region is on rainfall. The reservoir is thus regarded as an indicator of the overall water health of the entire area.
