The Aabach rises in the Sauerland around 6.5 km north of the border with Hesse between Brilon in the west and Marsberg in the east on the eastern edge of the Brilon plateau not far from the seam line to the Sintfeld in the north . Its source is located about 1000 m northwest of the center of the Brilon district of Madfeld , 650 m southeast of the unwooded Hogesknapp hilltop ( ) and 900 m northeast of the lightly wooded Stemmel hilltop (approx. ) at around altitude .
After its origin and after flowing through a small pond (approx. sewage treatment plant - it runs in a north-easterly direction through the maximum (mountain Brautlicht) high landscape of the Madfeld forest; it flows through the extreme northern foothills of the Diemelsee nature park and through the Aabachtal nature reserve .) on Holzweg, the Aabach tunnels under a residential area in the northern part of Madfeld over a length of around 200 m and then an arable land. Then - re-emerged and after flowing through a
In this forest landscape - between Madfelder Wald in the west and Fürstenberger Wald in the east - the Aue coming from the south (in the Aagrund ) flow into the Aabach , shortly afterwards the Große Aa flowing from the southeast and a little further north the brooks Bembruchssiepen and Schnadesiepen from the west a. Below the confluence of the last-mentioned brook, the Aabach is also called Große Aa and Großer Aabach according to the German map - named after this tributary of the Aabach .
The natural park Diemelsee leaving the Aabach flows further north and then in the nature reserve Great Aa in the pre-dam of the small Aabachstausees ( ) to lead the angliedert south to the south arm of the lake. The Aabach then flows through the actual reservoir, which lies on the seam line between the Brilon plateau in the south-west and Sintfeld in the north and between Bad Wünnenberg in the north-north-west and Marsberg in the south-east in a wooded landscape. Within this reservoir, the Aabach, in addition to the Kleine Aa coming from the south-east, also the Murmecke and Hassbach (Haßbach) creeks that flow from the south-west .
Below the dam of the Aabach reservoir, the Aabach runs in a north-north-westerly direction through a valley lined with wooded elevations, where it receives the water from the Heidebringsbach and Waldbach rivers coming from the southwest.
Finally, the Aabach achieved Bad Wünnenberg wherein it flows past the paddle in the park pond and bends a little later to the west, in order to ultimately at the former Franz mill to height in the coming from the direction east-northeast Alme influx Afte (Wiele) to open .
The headwaters of the Aabach are close to the Rhine-Weser watershed . This means that the water of the Aabach, which flows to the northeast, drains through the Afte , Alme and Lippe in a mainly west-northwest direction into the Rhine , while that of the small flowing waters that arise on the south side of the mountain ridge, mainly in a northeast direction the Hoppecke and Diemel flows into the Weser .
