Sau Reservoir

Sau Reservoir (Pantà de Sau) is an artificial lake in Catalonia on the Ter River, created by damming the valley in 1962. It is notable for the remains of a village that were flooded when the valley was inundated.

The most striking sight is the partially submerged church tower of the former village of Sant Romà de Sau, which protrudes above the water when levels fall. The shoreline and surrounding hills provide viewpoints for photography and short walks, and the reservoir is used for non-motorised boating and diving in permitted areas.

The valley was flooded when the Sau Dam was completed in 1962 to create a storage reservoir on the Ter River, and the old village of Sant Romà de Sau was largely submerged. Since then the site has been managed for water supply and local recreation rather than as an inhabited settlement.

The reservoir sits in the Osona region of Catalonia amid wooded hills above the Ter valley, close to the village of Vilanova de Sau. It is within driving distance of towns in inland Barcelona province and serves as a local outdoor destination.

• Submerged church tower: The exposed church tower of the former village becomes visible at low water levels, making late summer and dry years the best time for photography.
• Creation and use: The reservoir was formed on the Ter River in 1962 and is used for local water supply and recreational activities such as kayaking and diving.
