Sur les rives du lac de Guerl\u00e9dan en 1960

Le lac de Guerl\u00e9dan est un lac artificiel fran\u00e7ais situ\u00e9 d’une part sur les communes de Saint-Aignan et Sainte-Brigitte dans le Morbihan et, d’autre part, celles de M\u00fbr-de-Bretagne, Caurel et Saint-Gelven dans les C\u00f4tes-d’Armor. Il mat\u00e9rialise, en partie, la limite entre le Morbihan et les C\u00f4tes-d’Armor.<\/p>\n

(..) Ce lac a \u00e9t\u00e9 cr\u00e9\u00e9 pour alimenter le barrage de Guerl\u00e9dan. Le chantier dura sept ans de 1923 \u00e0 1930 et dut faire face \u00e0 de nombreuses difficult\u00e9s d’ordre g\u00e9ologique (creusement des fondations pour \u00e9liminer une poche d’argile en 1924), technique (barrage-poids de 208 m\u00e8tres de long) et financier. Faute d’argent, le chantier fut m\u00eame arr\u00eat\u00e9 de l’automne 1925 au printemps 1927. L’usine \u00e9lectrique associ\u00e9e au barrage est d’une puissance de 15 MW, et est exploit\u00e9e depuis 1946 par EDF.<\/p>\n

La cr\u00e9ation du barrage a eu pour effet de noyer la vall\u00e9e du Blavet sur plus de 8 kilom\u00e8tres, entra\u00eenant l’immersion de neuf carri\u00e8res d\u2019ardoises (\u00e9conomie de la r\u00e9gion depuis le XVIe si\u00e8cle), de maisons d’ardoisiers et de fermes.<\/p>\n

Elle a \u00e9galement supprim\u00e9 la continuit\u00e9 du trafic fluvial sur le canal de Nantes \u00e0 Brest, en coupant ce dernier qui empruntait \u00e0 cet endroit le cours canalis\u00e9 du Blavet. Seize maisons \u00e9clusi\u00e8res et 17 \u00e9cluses du canal de Nantes \u00e0 Brest ont ainsi \u00e9t\u00e9 englouties.
