Etang de Lemps sensitive natural area

Presentation

At the heart of Isle Crémieu lies the étang de Lemps lake, representative of the wetlands in Nord Isère. This 23-hectare site is part of the villages of Optevoz and Saint-Baudille-de-la-Tour.
A thematic trail and an observatory with disabled access introduce visitors to the aquatic life in the lake, including the remarkable European pond turtle, an endangered species. Recognizable by its black neck with yellow spots, they live, feed and breed at the water's edge.
An emblem of the site, the pond turtle is a threatened species due to the disappearance of its habitat. The étang de Lemps is an ideal environment (aquatic milieu, shade, adapted banks and dry slopes for the laying of eggs).
How do you recognize it? It is about 20cm long, the males have red eyes and the females have small, yellow eyes. They have a black body with yellow dots.
