Jungferweiher A dry maar that has been flooded again

North of the Ulmener Maar lies the Jungferweiher. It fills a shallow depression sloping towards the south. This previously silted up, older dry maar was flooded again in 1942 by damming the Nollenbach.

The Jungferweiher is now around 170,000 square meters in size and has a depth of 0.8 meters. Its water flows into the Ulmener Maar and is used to produce drinking water in the Cochem-Zell district. This water from the Jungferweiher has been technically treated since 1989, eliminating the phosphorus from agriculture. The Jungferweiher is now protected along with the Ulmener Maar and is known for its abundance of migratory birds.

The maar lies exactly on a SE-NW fault in the basement. This is the Lower Devonian, unstructured elm stage with sandstones, siltstones and shales.

Special features

A number of endangered bird species breed on the banks rich in rushes at the Jungferweiher. You can find meadow pipits there as well as common snipes. Ospreys can also be observed. There is a bird watching station on the western bank, from here you can easily observe the birds without disturbing them.
