The Darmbach spring is located above the Oberjägermeisterteich - the current version dates from 1937. From there the Darmbach flows through the eastern forest areas of the city, feeds the fish ponds along the Schnampelweg, flows from the Vivarium through a piece of meadow landscape, crosses the Botanical Garden and flows through the large Woog and the Rudolf-Mueller-Anlage; then runs underground and reappears in the west of the city, after flowing through the sewage plant.
