Punt dal Gall Dam, Arch dam at Italy-Switzerland border, Grisons
Punt dal Gall Dam is an arch dam spanning the Livigno valley and holding back the Spöl River to create a large reservoir. The structure sits at the border between Italy and Switzerland and serves as part of a hydroelectric system in this alpine region.
Construction of this dam took place between 1965 and 1968 by Engadiner Kraftwerke AG as part of alpine hydroelectric development. The project represented a significant expansion of energy production infrastructure in this border area during the post-war period.
The dam's name originates from a former bridge over the Gall stream, reflecting the local Rhaeto-Romance language heritage of the Grisons region.
Access to the dam area is via a toll tunnel at the crown that connects Livigno in Italy with the Swiss Engadin valley. Visitors should prepare for mountain weather and steep approach roads, checking conditions ahead of time.
The reservoir extends for about 12 kilometers and stores water to support the region's long-term energy needs. Most of the lake surface lies on the Italian side, even though the dam crown forms the border.
