The mailing pond is a man-made reservoir, which is fed by Katzenbach. It has an area of ​​260 m in east-west direction and 100 m in a north -south direction. The mailing pond in 1923 as the first and largest lippisches Waldschwimmbad planned.

In the late 1950s swimming was prohibited in the post pond for hygienic reasons and the outdoor pool Black Brink, the largest of the Detmold outdoor pools built as a replacement. Due to the low water levels of the cat's stream that usually dry in summer, the water level of the pond post large fluctuations. In the summer of 2009, the water level of the lake dropped to such an extent that for this reason and also due to the sharp increase in water temperature that live in the lake fish were threatened. A use of the THW was necessary to save the endangered fauna of the lake. These fresh water was pumped from the few hundred meters away Hasselbach in the first post pond with strong pumps.
