The Poursollet lake and village 1,649 meters above sea level, are part of Livet-et-Gavet and are the trailhead for many hikes in a sensitive natural environment.

In the 20th century, numerous hydroelectric plants developed all over the Romanche, creating thousands of jobs in electricity-dependent factories, but also an entire industrial city with housing, railways, movies, schools, parks.

A modern underground 92 MW plant will be built in Gavet, connected by a 9.3 km tunnel with a water dam outlet located upstream of Livet.

Eventually, the old power plants, non-recoverable, after more than a century of operation will be destroyed, and the riverbed will be redeveloped in order to develop tourism in the town of Livet-et-Gavet: paths, lake, bridge, landscape decoration etc.

Today Livet-et-Gavet is undergoing economic transition and aims to become a charming alpine valley, modern, combining hydro-electric generation, natural biodiversity and ecotourism (hiking, fishing, biking, climbing, paragliding).

Major film The Crimson Rivers was partly shot in the town, including the home of fr:Charles Albert Keller in impressive architectural part of the house, 4 storeys high and with a roof canted typical of the early 20th century, is built of stone (the inscription "Keller Establishments and Leleux" there still appears), while the second, reinforced concrete, is built on large piles in a dominant position over the Romansh: there was the office of Charles Albert Keller, from which he could observe all of its workshops and factories located on both sides of the river.
