description
The dam of the Pantà de Portbou, sometimes just called El Pantà or I Pantà , was built between 1973 and 1975. It is of the gravity dam type and made of concrete . Its height is 27.5 meters and the storage capacity is around 100,000 cubic meters. The water level is 130 meters above sea level. The longitudinal direction of the Pantà de Portbou follows the east-northeast direction.
The geological subsurface of the reservoir consists of relatively weakly metamorphic, paleozoic slate rocks from the Albères massif .
The reservoir belongs to the small category in Catalonia . Its purpose is to provide drinking water for the municipality of Portbou, but the water is also used for agricultural irrigation. Despite its undoubtedly regulating effect, a devastating flood occurred in October 1987 on the lower reaches of the Riera de Portbou.
The reservoir is surrounded on its south side by pine forests in an otherwise rather barren and treeless landscape and is therefore a worthwhile excursion destination.
