The Rummelbach is a 7 km long left tributary of the Reppisch in the Swiss canton of Aargau . It flows through the municipalities of Oberwil-Lieli , Berikon , Rudolfstetten and Bergdietikon , draining an area of ​​9.2 square kilometers.

In earlier times, the Rummelbach flowed through a ravine into the Reuss valley . With the retreat of the Reuss Glacier , a wall moraine formed, which extends from Künten to Lieli , and thus diverted the stream towards Reppischtal. Earlier names are Rumpelbach and Rollenbach . The upper course is called Fischgraben on older maps .

course

The stream rises in the municipality of Oberwil-Lieli near the Falterhau forest at 585  m above sea level. M. It initially flows in a north-westerly direction through Berikon, where it was partially laid under the ground. Here it makes an arc and now flows in a north-easterly direction. After the small forest in Gunzenbühl, it follows the main road Mutschellen - Dietikon and finally flows north of the wastewater treatment plant on the border with the canton of Zurich from the left into the Reppisch.

Flood

The stream usually has little water. When it rains heavily, however, the water from a relatively large catchment area enters the stream. This last led to severe flooding in the spring of 1999. Because the transition into the tube in Berikon was not able to cope with the masses of water, the stream overflowed its banks and flooded some underground garages and houses. Various renaturation measures and improved flood protection have meanwhile defused the problem and given the stream back its old bed.
