The Susqueda Reservoir was the last and largest water catchment system to be built in the river Ter (Sau-Susqueda-el Pasteral), which has the function of produce electrical power, reserve water and regulate the flow of the Ter. At the same time, it makes for a considerably appealing landscape, given that it is found amidst a lush, hilly landscape.

Construction began in 1963, after stiff resistance from area residents, and was completed in 1967, drowning the village of Susqueda in its waters, plus the fields and farms of the Susqueda and Querós valleys.

The Susqueda dam is a notable work of engineering. The dam has a double-curved vault, made of concrete with several galleries that cross it internally, among which is the well-known hall of the columns, located in one of the lateral stirrups, which is not usually open to visitors.
