Construction of fish ladders in the azud de Xerta (Tarragona)
In the lower section of the river Ebro, from Flix to the mouth, there is only one obstacle that causes a breakage of river continuity: the Xerta weir. Currently there is a fish ladder in the weir, that is of a successive pond typology, located about 80 m from the right bank, which is not considered suitable for the passage of river wildlife due to its geometric characteristics and typology. This project involves the construction of a new fish ladder that allows the presence, in the delta area, of ​​wildlife species that currently have a minority representation.
