On most maps it is called "Lac d’Ilay". The other name probably comes from the small island "Île de la Motte" which is located in the lake.

This glacial lake, with its clear waters, offers an idyllic setting for a walk or a contemplative break by the water. The paths that surround it allow you to explore its peaceful banks, offering superb views of the Jura mountains and the reflections of the landscape in the lake.
