The Kochhart flows at the northern edge of the municipality of Bondorf, originating from its officially recognized main upper course, the Tiefenschleipf, and its right tributary, the Haldengraben.

The Tiefenschleipf begins between Oberjettingen and Unterjettingen, initially flowing east, then for a longer stretch southeast, and finally receiving the intermittent Zigeunerbrünnle from the right, coming from the northern edge of Mötzingen.

Notably, the lower section of the Kochhart near Reusten features a terrain incision approximately fifty meters deep, with a stream, rocks, and calcareous dry grassland, designated as a nature reserve covering 107 hectares.

Today, during dry weather, 400 to 600 cubic meters of water per day flow from the sewage treatment plant for the Rottenburg district of Hailfingen and the municipality of Bondorf.

This spot is at the center of an oval shell limestone saddle that is two to four kilometers in diameter, and from there, there is a good view into the two canyons that the Ammer and Kochhart have cut into the land.This Baden-Württemberg location article is a stub.
