geography

Erpfquelle

The Erpfquelle in Erpfingen

The Erpf rises in Erpfingen from a karst spring near the house at Stettener Straße 26. This is known under the name Brechlöchle, more rarely also whey spring. It is a dammed spring pool just north of the local thoroughfare in which the source with an average bulk of 60 l / s (min. 1 l / s max 500 l / s) flows. After less than a hundred meters in the village, the draining Molkebach reaches a longer source branch from the eastern edge of the village, which previously only had an open course there in sections.

course

The Erpf initially flows in a westerly direction, bends south and flows past the Erpfmühle north of Stetten into the Lauchert .
