Krumm is a short river on the edge of the Swabian Alps from about ten to fifteen kilometers in length. It originates at the base of Mt. Rechenberg near the Fuchshof in Rechenberg, from where the river makes its way through Ottenbach and Krummwälden up to its mouth on the field of Eislingen in the Fils. The hamlet Krummwälden, which was called in former times as "Welden," carried for some time the name of this river. It was changed to avoid ambiguity.
