Border water permits for Sauer, Our and Mosel are available at the Tourist Information Bollendorf and at the administration of the South Eifel Association (Verbandsgemeindeverwaltung Südeifel) in Irrel.

In principle, the border water permits are valid for the Sauer, the Our and the Moselle, but only for the river sections that run along the border between Germany and Luxembourg.

A fishing license or an identity card must be presented for issuance. Children up to and including 14 years of age do not need a fishing license, but must fish in the company of an adult who has the license. A pre-order is not required (except for groups).

Any additional regulations and special rules are summarized in a booklet that anglers receive when they receive their boundary water license.
The permits are available for three time periods:
One week (5,00 €)
One month (10,00 €)
One year (15,00 €)
(Payment is possible only in cash at the issuing office).
