The Petit Maclu, located to the northeast, has an area of 5 hectares, a length of about 500 m, and a maximum width of about 120 m. Its greatest depth is 11 m. It lies entirely within the municipal territory of Le Frasnois.

Beautiful view of the lake, and afterward, we had a lovely swim in the lake. Nice bar with delicious ice cream.

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.
