LAC D'ILAY

The very elongated shape of Lake Ilay follows the south-western / north-eastern orientation of the Jura massif. A small narrow channel connects it to the Grand Maclu. A small island emerges in its centre: it is the "clod". This is why it is also called "Lac de la Motte". Archaeological excavations, notably by Jean-Luc Mordefroid's team, have revealed remains of a Benedictine priory, Saint-Vincent-de-la-Motte, dating back to the Carolingian period. It was occupied until the 15th century. Swampy lake and classified in ^2nd category for fishing, fishermen are stationed in boats on the water. By foot, only the northern tip, on the Frasnois side, is accessible, bordered by grassy slopes where swimmers and even canoeists can rest. Its deep waters supply 7 surrounding municipalities.
