This dammed-lake depicts a paradoxical image, reconstructing an image of nature by an effect of industry, representing a pure human act by banishing the humanised landscape. More surprising yet, this reservoir landscape, which empties every ten years offering a glimpse into a village of the past, and this apparently imprisoned water, is still in permanent communication with the Arc and Isère by intimate tunnels joining L´Ecot and Malgovert. Landscape with double face and double bottom.
