Lake Guerlédan, Artificial lake in Brittany, France
Lake Guerlédan extends for 12 kilometers through central Brittany, containing 52 million cubic meters of water between the departments of Morbihan and Côtes-d'Armor.
The construction of Guerlédan Dam from 1923 to 1930 submerged seventeen locks of the Nantes-Brest canal, transforming the former slate valley into the largest artificial lake in Brittany.
The Abbaye de Bon-Repos, established in 1184 near the lake shores, maintains its architectural legacy through continuous restoration efforts by dedicated local craftspeople.
Visitors access multiple beaches and coves around the lake for swimming, while designated areas support water skiing, kayaking, paddle boarding, and fishing for pike species.
The complete drainage of Lake Guerlédan in 2015 revealed a preserved underwater landscape of submerged locks and buildings from the pre-dam industrial era.
