The Bléone Fishing Club has created and developed this artificial, man-made lake on the banks of the river to enable its members to improve their fishing skills. For many years, it has also set up a fishing school to teach children how to fish in a way that respects the natural environment.

The Maison de la Pêche et de la Rivière (The River & Fishing Centre) was created to promote the Bléone river. The entire basin (including rivers and streams, riverside forests and wetlands) is made up of diversely rich environments for numerous species: Fish (trout, sculpin, vairone, barbel) - Crustacien (crayfish) - Mammal (beaver) - Bird (European bee-eater).

The Bléone river has been relatively unaffected by developments and has retained a fairly natural dynamic. Since 2015 the Bléone river and its basin benefits from an Ecological River Management Programme, which ensures the efficient, collective and coordinated overall management of the river and its catchment area.
