These woody flanks are populated by Narrow leaf Ash, Willows, Poplar and Alder trees.

The dam was built as to provide public water supplies for the surrounding municipalities.

The overwhelming need for water in the summer by the local population necessitates its construction despite the opposition.

Restoration has been carried out along a 180-hectare (450-acre) stretch of the left bank of the river with the aim of encouraging the population of the endangered Iberian lynx[5] and the Bonelli's eagle.

This work also includes the National Centre for the Captive Breeding of the Iberian lynx.
