The River Blavet

Here, the river Blavet joins the Scorff and flows into the Atlantic Oceans in the bay of Lorient. This coastal river is 163 kilometres long and rises in Bourbriac in the Côtes-d’Armor department. Feeding into Guerlédan lake since the 1930s, the river was channelled in the 19th century. From Pontivy to the gates of Hennebont, bridges, ports and locks were built along it. The estuary begins at the last lock in Polvern, where the freshwater mingles with the rising seawater. Its wooded banks are interspersed with reedbeds and rushes, salt marshes and mudflats.
