It is the longest river situated entirely within the county of Oberbergischer Kreis and the third longest tributary of the Agger. GeographyThe river rises in the region of Bergisches Land in the municipality of Reichshof. Its source is located about 700 metres north of the village of Hahn on the southern slopes of the Silberkuhle ({{Höhe|514.6}}) at a height of {{Höhe|446|DE-NHN|link=true}}. The Wiehl initially flows in a southerly direction and passes through the parish of Wiehl. Near Wildbergerhütte it turns towards the west. Between Nespen and Brüchermühle it is impounded by the Wiehl Dam. After passing Brüchermühle it is impounded again, this time by the Stauweiher Bieberstein. From here it flows mainly in a northwesterly direction. After passing through the parishes of Oberwiehl, Wiehl, Bielstein and Weiershagen, it empties into the Agger near Wiehlmünden at a height of {{Höhe|145|DE-NHN}}. TributariesThe following is a list of Wiehl tributaries with their orographic orientation (left/right), location of their mouth and elevation at the mouth.
