course
The brook arises at 589 m above sea level. M. through the confluence of the left source stream Grossmattbach and the right source stream Weidbach in a ravine in the Häderholz forest .

Shortly after its confluence, the stream turns to the northwest and forms the canton border for around 120 meters before it crosses over to Zurich and runs parallel to the Stigelmattbach . The stream now enters the Reppischtal and flows a little later in the area of the Reppischtal shooting range at 439 m above sea level. M. in the lower reppisch.

history
In the past, there was a coal mine in the Cholgrueb forest , which is still named after it today , which was used in the 18th century. Today, however, everything has fallen apart and nothing can be seen anymore. According to a report by the Pyrotechnic Society in Zurich , this coal seam was 9 to 12 centimeters thick.
There is also an old legend about the Malefizgraben, according to which seven gentlemen owned a castle here and spent their time plundering the area around Rudolfstetten, Dietikon and Friedlisberg. One day, during a nocturnal thunderstorm, the lock broke into all its individual parts and the gentlemen no longer appeared in public from then on. It is said that at night you can see them counting money on the path by the Burgstall .
flora
In the upper reaches initially found woodruff - beech forest with lungwort , around the mouth of the Häderlibachs sedges -Bacheschenwald with wild garlic and small areas Linden - Toothwort -Buchenwald. The lowest section in the canton of Aargau is again characterized by woodruff beech forest, partly with lungwort, but also by sedge-brook ash forest with giant horsetail . The lower reaches of the Malefizgraben in the canton of Zurich is characterized by typical wood millet-beech forest and at the mouth there is arum- beech forest.
