Swimming in Lake Servières is a major cause of degradation of the quality of its waters. It also affects the aquatic grass beds essential to the lake and its fauna. Preserved in winter by cold and ice, Lake Servières is now also protected in summer by four seasonal caretakers hired in spring 2020 by the Departmental Council of Puy-de-Dôme. Responsible for enforcing all the bans in effect, such as swimming, wild camping, and lighting fires, they are assisted by a nature warden from the Auvergne Volcanoes Park.
