The Lake of Annecy had originally two basins which were separated in prehistoric times by a ridge between the “Duingt” headland and the “Roc de Chère”.
This ridge has now been submerged and the straits of Duingt link the “Big Lake” in the north and the “Small Lake” in the south.
The Lake of Annecy (2800 hectares) is not very deep (45 metres on average). It is fed by alpine torrents and small watercourses, the biggest of them is the “Eau Morte”. An original aspect is that the lake is also fed by a powerful underwater spring, the “Boubioz” which gushes out at a depth of 82 metres, in the north of the “Crêt du Maure”, 250 metres from “la Puya” (pumping station).
In order to protect this superb environment, major cleaning up and the installation of a main sewer encircling the whole lake have made it possible to preserve the purity and clarity of its water.
Thanks to the quality of its ecosystem, many types of fish live in the lake :
char, lake trout, whitefish, powan, perch, carp, roach, chub, etc…
All you need to satisfy fishermen and gourmets!
Also to be noted is the “Bout du Lac”, a nature reserve with its reptiles, ducks, swans and even beavers!
