The next great step down the Duero from Aldeadávila, still inside the Arribes del Duero gorge on the international border. Like its upstream neighbour it is a deep hydroelectric canyon reservoir rather than a gentle stillwater — granite walls, cold clear depths, and a fish community led by zander, wels catfish and pike, with barbel on the shallower margins and around the Águeda and other tributary mouths. It is slightly less sheer than Aldeadávila in places, which opens up a little more fishable bank, but the character is the same: a predator water best approached with a boat, big flies, and modest expectations of numbers in exchange for the chance of a serious fish.
