The largest reservoir in Castilla y León — a vast, deep impoundment on the lower Tormes just before the river plunges into the Arribes canyon, feeding the Villarino hydroelectric station. This is big, serious water: hundreds of feet deep against the dam, with long flooded arms reaching back up the Tormes valley. It is best known as zander (lucioperca) country, with pike holding over the drop-offs and barbel and carp working the shallower upper arms and inflows. The scale rewards a boat and a plan rather than blind bank fishing. Heavy summer drawdown for power generation exposes wide margins and concentrates fish toward the deeper basin and the dam end.
