Tributaries to the Lahn include the Dill, the Weil and the Aar Rivers. The lower Lahn has many dams with locks, allowing regular shipping from its mouth up to Runkel. Riverboats are also used on a small section north of the dam in Gießen.
The Lahn originates at the Lahnhof, a locality of Nenkersdorf, which is a constituent community of Netphen in southeastern North Rhine-Westphalia, near the border with Hesse. The source area is situated along the Eisenstraße scenic highway and the Rothaarsteig hiking trail.
The settlement, which has about 280inhabitants and 80houses, lies higher up the valley from Wald and Vorderwaldberg on the southern slopes of the Salzach valley, between 900 metres (2,950ft) on the valley floor and the B165 Gerlos Road, 1,100 metres (3,610ft) on the Old Gerlos Road (Alten Gerlosstraße), the L133, (Ghf. Grübl) and 1,200 metres (3,940ft) in the Lahnbauer wilderness with several other farmsteads. In addition the village has a halt, Lahnsiedlung, on the Pinzgauer Lokalbahn, the Postbus line670 Zell amSee– Krimml stops in the Finksiedlung.
Also part of the village are the eastern slopes of the Trattenbach valley – the western slopes belong to Rosental (Gemeinde Neukirchen) – to the north, with the alpine meadows of Besensteinalm, Wurfgrundalm, Wurf-Hochalm, Happingalm, Happing Hochalm on the Gernkogel and Trattenbachalm, Trattenbach-Hochalm on the Kröndlhorn. The parish area runs up to the state border with Tyrol at the Filzenscharte ridge, extending about 8.2 kilometres (5.1mi) from north to south.
While it was within some distance offshore, an explosives-laden dinghy rammed the starboard side of the tanker and detonated. The vessel caught on fire and approximately 90,000 barrels (14,000m3) of oil leaked into the Gulf of Aden. Although Yemeni officials initially claimed that the explosion was caused by an accident, later investigations found traces of TNT on the damaged ship.
One crew member, a 38-year-old Bulgarian named Atanas Atanasov, was killed, and 12 other crew members were injured.
The fire was put out, and four days later Limburg was towed to Dubai, United Arab Emirates. The damage to the tanker was around $45 million USD. The ship was sold to Tanker Pacific by 2003 under the new name Maritime Jewel, who repaired her for $8.5 million USD.
Limburg has a highly distinctive character. The social and economic trends that affected the province in recent decades generated a process of change and renewal which has enabled Limburg to transform its peripheral location into a highly globalized regional nexus, linking the Netherlands to the Ruhr metro area and the southern part of the Benelux region. A less appreciated consequence of this international gateway location is rising international crime, often drug-related, especially in the southernmost part of the province.
