Photographer's Note

Along the lake of the Bourget in Savoie.
The photograph is taken near the village of Conjux, on the way of back from holidays.

Larger natural lake of glacial origin of France, located at the north of the department of Savoie, the lake of Bourget belongs to the postglacial lakes of the Alps. It was formed after the last Glaciation of Wrm, approximately 19.000 years ago by the withdrawal of the large glaciers of the quaternary one.

Of a surface of 44,5 km (4 450 hectares), the lake stretches all in length in a North-South axis on 18 kilometers, and with a width ranging between 1,6 and 3,5 kilometers. Its average depth is 85 meters, and its maximum depth of 145 meters.

Of an average altitude of 231,5 meters, it is bordered:

in the west by the last buttresses of the southernmost Jura, with the Chain of the Spine 1.482 meters and its Tooth of the Cat which culminates with 1.390 meters;
and in the east by the Solid mass of the Wallows, of which the Mount Revard (1 538 meters), as well as the mountains of Cessens, of Chambote, Corsuet and the hill of Tresserve.
Its catchment area of 560 km is occupied by the thermal city of Aix-the-Baths, which borders it on its bank is, and more with the south, by the town of Chambry, capital historical of the duchy then kingdom of Savoy, today prefecture of the department of Savoy, located at about fifteen kilometers. These two cities form two agglomerations adding up 170.000 inhabitants (in 2004).
