It is situated in the Solvente ravine, downriver from the dam head of the Hydro-electric Power Station of the same name, on the boundary of the municipal districts of Ojós and Blanca.
Main Dam Diversion
It is formed by an overflow gravity dam with a polygonal ground plan, built on debris, with a double screen of reinforced concrete piles tangent between each other, with a separation of 3 m between both rows, this area having been injected in order to ensure the watertightness of the screen.
The maximum length of the piles is 17 m, reaching the limestone existing beneath the debris.
