The Talbach is a good eight kilometers long, west-southwest and left tributary of the Aare , which flows through the Schenkenbergertal in the Swiss canton of Aargau .
geography
course
The Talbach rises at an altitude of about 597 m above sea level. M. in the municipality of Thalheim and flows into the Aare at Schinznach . The stream has a length of around eight kilometers, of which around three kilometers are in the municipality of Thalheim. The other five kilometers are in Schinznach. At the Langmatt the stream has a two meter high waterfall.
The headwaters of the Talbach are located in the Riedmatt basin in Thalheim. There are two arms that flow together at the Riedmatt in Thalheim. The shorter arm is a 20 meter high waterfall below the Staffelegg. The second arm flows from a tube below the Staffelgg pass road. Several small streams flow into the Talbach, the most important of which are the Gländbach , Hegibach and Gäcketbach . After the Seinach Bridge in Schinznach-Dorf, the stream in the Talbach Canal crosses the Schinznacherfeld. The outlet of the nursery nursery also flows into this channel. The stream flows below Schinznach-Dorf into the upper water canal belonging to the Aare, which is passed in a pipe under the Aare canal and then flows into the old course of the Aare.
The Talbach meandered "wildly" through the valley floor in Thalheim. On the slope side to Gislifluh a pond was created for the operation of the village mill. In the lower part of the stream, in particular, structural measures were taken several times to divert and channel the stream. Today the stream mostly runs in a stream bed.
Catchment area
The 13.51 km² catchment area of the Talbach lies in the eastern part of the Swiss Jura Mountains and is drained through it via the Aare and the Rhine to the North Sea.
It consists of 35.1% wooded area , 51.1% agricultural area , 13.5% settlement area and 0.3% unproductive areas.
The area distribution
The mean height of the catchment area is 502.6 m above sea level. M. , the minimum height is 334 m above sea level. M. and the maximum height at 798 m above sea level. M.

Hydrology
At the confluence of the Talbach into the Aare, its modeled mean flow rate (MQ) is 360 l / s. Its discharge regime type is pluvial jurassia, and its discharge variability is 24.
Water quality
The quality of the water in the Talbach is rated as very good. The ecological status is classified in quality class I-II and the guideline values for the chemical parameters are generally adhered to. Seven pesticides were detected in the investigation , whereby the legally prescribed values were exceeded only for the pollutant isoproturon . A slightly increased copper concentration was also found in the sedimentary rocks of the Talbach .
Hydraulic structures
bridges
The numerous bridges are impressive, the best known are:
Surname | Explanation |
---|---|
Thalheim village bridge | Old stone arch bridge |
Winkel-Talbach Bridge | Old and new stone and concrete arch construction |
Kastelerbrücke | New bridge; it leads highest over the Talbach |
Steinach Bridge | Bridge with an intersection and a bus stop of the same name |
Canal bridge | Last bridge over the Talbach, right next to the A3 |
Mills
No electricity is generated at the Talbach. In the past and still today, water power is or was used in the form of mills. There used to be several mills along the valley stream and also on the side streams.
Former mill | Waters | Receive | place |
