Bisses are the historic irrigation channels of the Valais. A bisse is an open ditches delivering priceless water from mountain streams – often by daring routes – to arid pastures and fields, vineyards and orchards. Many bisses are still in use today and so are carefully maintained. Numerous trails accompany these historic watercourses, inviting visitors to varied hikes on historic trails.
La Raye des Verbiérins and Bisse du Levron
It drew its water from the Torrent de Versegères below the Chaux glacier at an altitude of 2,500 metres; this channel irrigated the entire territory of Vollèges commune. Another source, La Raye des Verbierins, added its waters to the channel’s flow below the Mont Fort hut. Since 1957 when the Mauvoisin Dam was built, a tunnel from Louvie to the Col du Lin has carried water to Le Levron and Vollèges.
