About Mequinenza Dam

Mequinenza dam sits at the confluence of the Ebro and Segre rivers in the province of Zaragoza, Aragón. Completed in 1966, the gravity dam holds 1,373 million cubic metres — the largest reservoir in the Ebro basin. The reservoir, known locally as the 'Mar de Aragón' (Sea of Aragon), stretches over 110 kilometres upstream and is renowned internationally as one of Europe's premier sport fishing destinations, particularly for catfish (siluro) and carp. The dam is a major hydroelectric facility, and its position near the junction of the Ebro's two largest tributaries gives it a strategic role in managing the basin's water resources. The town of Mequinenza was partially submerged by the reservoir's creation, and the community was relocated — an experience chronicled in the novels of local author Jesús Moncada.
