The 25 km-long Souffel river rises at an altitude of 215 m in the commune of Kuttolsheim and flows eastwards into the Ill near Strasbourg. Originally, this winding river meandered through a damp valley floor that was regularly flooded. Post-war agricultural development overcame the river's natural meanderings, and from the 19th century onwards, dams and a canal were built, which later became the bed of the Souffel. By transforming it into a straight waterway in places, this work had the effect - among other things - of impoverishing the flora and fauna around the Souffel. Today, aware of the need to protect the environments associated with this river, the local authorities concerned have embarked on a program to restore and renaturalize the Souffel, aimed in particular at reconstituting functional natural environments.
