The Olef, tributary of the Urft |
The Olef rises on the Ramscheider Höhe, near the Zitter Forest, about 2.2 km (1.4 mi) southwest of Hollerath at an elevation of 639 m above sea level (NHN), immediately on the state border. From here it flows initially northwest and through the woods of the Dreiherren Wald. The valley of the Olef forms the state border here which runs along the river. From its confluence with the Wiesbach it enters Germany. It then forms inter alia, the eastern boundary of the safety zones of the Elsenborn Military Training Area. The river course changes direction in a wide arc to head east.
In the next section the Olef flows through the Schleiden Forest (Forst Schleiden) and is impounded to create the Olef Reservoir in front of Hellenthal. In Hellenthal it is joined from the right and southwest by the Platißbach. At the end of the village of Hellenthal, near Kirschseiffen, the river turns north. At the northern edge of Blumenthal it picks up the Reifferscheider Bach from the right. Other villages en route are Oberhausen, Schleiden, Olef, Nierfeld and Gemünd. Here the Olef discharges into the Urft from the left at a height of 334 m above NHN.
Along its 27.9-kilometre-long route the Olef descends through 335 metres, which represent an average riverbed gradient of 12 ‰. It drains an area of 196.073 km2 (75.704 sq mi)
