Environment

According to a survey of water quality data from the year 2001, the Oetternbach the water quality class III is assigned. This means that the stream is critically loaded. Recent studies from 2008 show an improved quality situation. The upper reaches and the lower reaches of the Oetternbaches be associated with the water quality class II. The middle course between the confluence of the creek Sylbecke and the fur has a poorer water quality and grade II -III ( critically polluted ) attributed. In July 2006 there was a fish kill in Oetternbach. This was caused by contamination of the creek with large amounts of manure. In 2006, the upper reaches of the Oetternbachs including surrounding areas has been designated as a nature reserve with a size of 108 ha. It is a flowing water system with source streams, grassland and woodland stands.
