A reservoir on the Duero itself, deep in the Arribes del Duero natural park where the river forms the Spain–Portugal border in a sheer granite gorge. It feeds one of the most powerful hydroelectric stations in Spain, and the setting is dramatic — cliffs of bare rock dropping straight into cold, deep, clear water with griffon vultures overhead. This is not a sight-fishing flats venue: it is a deep canyon water dominated by predators, with zander and very large wels catfish (siluro) in the depths and pike and barbel where the side-streams and shallower necks let fish hold. Bank access is genuinely difficult on the gorge sections; the upper necks and tributary mouths are the realistic fly water.
