It comes to the surface near the street of Knüllkamp in Osdorf. Nearby, from the right, the small stream of Müllergraben flows into Luruper Moorgraben. It then crosses the street of Bornheide, the main road of Osdorfer Born. Finally it flows into Lake Helmuth Schack in the recreational area of Born Park.
