Lac Genin, Mountain lake in Oyonnax, Charix and Échallon, France
Lac Genin is a mountain lake in the Jura massif at 850 m altitude, measuring 380 m long and 330 m wide, with a maximum depth of 24 m. It lies in a depression of the Charix syncline and is fed by runoff and underground springs; its overflow drains south through a visible underground passage. The shores are lined with firs, spruces and broadleaf trees, and a pale house with a dark roof stands among the trees on the far bank.
Lac Genin has been classed as a picturesque site since 1 March 1935. Until the mid-20th century, several farms stood around the lake, cultivating the surrounding fields and meadows; all of them now lie in ruins.
The lake is nicknamed "little Canada of Haut-Bugey", a name that reflects its setting among firs, spruces and broadleaf trees. Until the mid-20th century several farms worked the fields and meadows around the water; all now stand in ruins. In winter, when the ice reaches 13 cm, ice skating on the lake is allowed and managed by the lakeside inn.
A lakeside restaurant serves regional food, and guest rooms are available for those wanting to stay nearby. These basic facilities make it easy to spend time at the lake and explore the surrounding area.
