Pantà de la Baells, Reservoir in Spain

Pantà de la Baells is a large reservoir in the Berguedà region, created by a dam built across the Llobregat river. The water stretches across a wide area and is surrounded by green hills and forest.

The dam was built between 1970 and 1976, fundamentally changing the landscape by flooding several small villages including Miralles and La Baells. Since then, it has served to store water for Barcelona and the surrounding area while controlling flooding on the Llobregat river.

The reservoir takes its name from the flooded village of La Baells, one of three settlements in Cercs submerged along with Miralles and Sant Salvador de la Vedella. Since 2002 the Festival de la Baells has been held on its shores, originally a one-weekend Festival del Riu and later extended from mid-June to mid-September by the Agència Catalana de l'Aigua.

The C-16 road runs along the right bank of the reservoir between the Cadí tunnel and Berga, and the C-26 crosses the water between Berga and Ripoll. The Museu de les Mines de Cercs leads guided visits inside the dam. Boats are limited to under 16 knots, and rowing, sailing and archery are practised on and around the water.

The dam is a double-curvature arch structure inaugurated on 17 February 1976; its concrete contains river cobbles of various sizes, with reinforced concrete used for some finishes. The Museu de les Mines de Cercs runs guided visits inside the dam. Since 2015 the Via Blava de La Baells has been part of the Vies Braves project, not a coastal route.
