Water quality

In 2001 the Ilse in the upper reaches, below the confluence of the Taller Bach, was heavily polluted ( water quality class III) and improved its water quality to water quality class II (moderately polluted) up to the confluence with the Bega. According to investigations from 2008, almost the entire course shows moderate exposure (quality class II). Only the estuary area has a lower quality and is assigned to water quality class II-II (critically polluted).
