In the 20th century, the Sarine underwent a major transformation with theconstruction of the Rossens Dam. Completed in 1948, the structure gave rise toLake Gruyère and left a lasting imprint on the landscape, the economy and thedaily life of the region.
Designedfor hydroelectric power production, the dam quickly became a cornerstone ofregional development. Electricity generated from the force of the watersupplied homes, infrastructure and economic activities, contributing to theindustrialisation and modernisation of the district and beyond. The Sarine,once solely a natural resource, thus became an economic engine.
Yet this energy development imposed a new rhythm on the river. Its course, once free andunpredictable, is now regulated to optimise production and ensure the safety ofthe installations. This control of water has profoundly reshaped naturalenvironments as well as the way the territory is used.
But this contained power requires constant vigilance. During the opening of thefloodgates, water levels can rise rapidly downstream, reminding visitors thatthe Sarine remains a living force. Here, the river is neither entirely wild norfully mastered: it embodies a delicate balance between human needs, economicimperatives and natural dynamics.
