etymology

The name is derived from a Middle Low German basic form * Rīfen-beke. “Rīfe” means something like incision , so that there is a meaning “the cutting, cutting brook”. Historical names for the Riefenbach are Reiffenbeck 1548, Riffenbeck / Riffenbach 1578, Reiffen Beeck 1666, (im) Rieffenbeeke 1689 and 1784 Riefen Bach .

course

The source is on the Huneberg in the Harz National Park . First of all, the Riefenbach flows northeast on a steep slope, the first side streams are already included after a distance of about 500 meters. About 750 meters northeast of the source, a ditch diverts part of the water to the Great Hune , a tributary of the Oker . After two kilometers of scoring stream enters the named after him Riefenbachtal a containing about 300 meters of the wheel runs west parallel to the valley. Half a kilometer before its mouth, the Riefenbach reaches the urban area of ​​Bad Harzburg, flows through the spa gardens as a largely canalized stream and flows into the Radau 40 meters west of federal highway 4 .

Structural quality

The Riefenbach is a fast flowing mountain stream, the bottom of which is covered with rubble and gravel. Since the water flows almost completely in the unpopulated high Harz and there are no other significant pollution such as contaminated sites of heavy metals from the Harz mining history, the brook is given the biological quality grade I in the water quality report of the NLWKN from 2002 .

A total of five species were found that are on the Lower Saxony Red List of Threatened Species; they are all caddis flies .
