This reservoir dam, built in 1903 by the Tournier company, was “intended to store the Lizon’s waters during floods and work stoppages for better distribution during working hours” (Agreement between petitioners, 1903). Located around 70 metres after the bridge, the dam also served to improve the factory’s ability to produce electricity to supply the neighbouring municipalities and to resell unused driving power to the nearby wood turning workshops. Sold to the Union éléctrique (electricity union) in 1937, this hydro-electric plant has now fallen into ruins.
