Lac du Colombiers - Anse (69)

The Colombiers' lake was previously a graviere, it is nowadays a fishing spot, and turns partially into a resort station with a beach and some activities during summer. Its past explains the important depth that can be found in the middle. It's very interesting to notice the underwater island in the north of the lake, which is unexplained so far.

There is a car somewhere in the eastern part, as there is never enough space in the parking, you shouldn't be surprised by this creative extension for overcrowded days.

The deep zone is surprisingly near the sand beach, while the western part shows a 7 meter plateau. The shallow north part is full of frogs, but I never caught something to be proud of over there.
