The creek's name has been established only since the 19th century; the reasons for this are unclear. Previously it was known as Willerbach.

Course

The Böse Sieben is fed by two sources, the streams Vietzbach, known also as Goldbach, and Dipplesbach, which unite in Ahlsdorf. According to the LHW, the Böse Sieben is 15.22 km long. Other tributaries include the Kleibigbach, Goldgrundbach, Pfaffengrundbach, Saugrundbach and Wolfroder Bach. Since these can swell rapidly during rains, and cause rampant floods across the Mansfeld region, the explanation for the name may be found here.
