Chambon lake

Lake Chambon is fed by the waters of the couze * Chaudefour which takes its source towards 1 580 m altitude in the Dore Mountains, between the Puy de Cacadogne and the Dent de la Rancune, in the Chaudefour Valley National Nature Reserve.

The creation of the lake is the result of a volcanic dam caused, there is 16 000 years, by the eruption of the Puy du Tartaret. The volcanic flow of Tartaret obstructed the natural course of the Couze Chaudefour by rising across the glacial trough of the same name causing the appearance of a first dam lake. Then there is 2 600 n the collapse of the Dent du Marais helped raise the level of the lake.

Mainly located in the town of Chambon-sur-Lac, the south-eastern part of the lake is in the municipality of Murol. Shallow (4 m), but quite large (60 he has), the lake is located 875 m d’altitude.

The couze Chaudefour carries, today, such a quantity of alluvium that the lake has already halved its surface.

We can realize this when we know that the notches in the rock that border the valley in front of the village of Chambon are the remains of a path that once ran along the shore..

This alluvial load entails a risk of biological death of the water body by irreversible eutrophication.

Today, the challenge is the management of tributaries, upstream breeding activities and individual sanitation.

It is also necessary to ensure the balance between urbanized tourist areas and rural or natural areas.

Many improvements have been made (beaches, lake tour, restoration of upstream wetlands).

The shores of Lake Chambon are very indented, except to the east and north-west where two beaches have been designed for swimming and water activities. A real resort, you can enjoy Lake Chambon, summer, like winter.

A path allows you to go around it in about an hour. Part of the trail has been reorganized into 2006 and portions on stilts allow you to follow the shore of the lake passing through swampy areas. Around the lake 3,5 km.

It is possible to get there on foot or by bike via the Voie Verte from Murol and then go around it.

In volcano-sedimentary lands, there are diatomites * and fine clay cinerites * rich in leaf imprints.
