Lake Servières, located in the municipality of Orcival in Puy-de-Dôme, is an exceptional natural site, instigated by landscapes and enjoying a ZNIEFF ranking. However, it is threatened by the high number of visitors, particularly in the summer, which causes erosion of the shores of the lake. In order to preserve it and as part of its policy of sensitive natural areas, the Department acquired the site from the Michelin company.
