Located at the bottom of the valley, this stream and the wetland that borders it play a fundamental role in the water cycle. The wetland acts as a sponge and stores rainwater in winter; it helps to limit floods and returns water to the stream during dry periods. Acting as a natural filter, the sludge and the plants that grow in it contribute to improving water quality by eliminating pollution. This environment is also colonized by the willow, easily identifiable in spring by its white flowers or catkins.
