Lac de Sylans, Lake in Le Poizat-Lalleyriat, France.
The lake spans 49.7 hectares with a length of 2 kilometers, a width of 250 meters, and reaches depths of 22 meters.
Following a landslide on the northern cliff during medieval times, the natural dam formation blocked the Doye River, creating this mountain lake.
The remains of the ice factory on the western shore represent a significant industrial heritage from 1865 to 1914, when lake ice was distributed nationwide.
Fishing permits for pike, whitefish, and carp can be obtained at the Relais des Mousquetaires store in Les Neyrolles.
The lake's water filters naturally through underground passages, emerging as the source of the Doye River, which supplies the Cristaline bottling plant.
