The Bagaúste dam is located between the municipalities of Régua and Lamego, 4 kms upstream of the city of Régua, at km 105 of the Douro waterway (distance to the mouth). It was inaugurated in 1973.
This dam has a gap of about 27m, and pass through its lock the Cruises that sail between the city of Régua and the village of Pinhão.
The dam is next to the EN222, a road that connects Régua and Pinhão, next to which there is a car park. You can park here and watch the cruises that pass the lock, a process that takes up to 30min and often gathers many people to observe the passage of boats.
