Eichholz Maar The renatured maar

People have demonstrably used the Maart Funnel since Roman times. It was drained several times and then refilled for fish farming. In 2007 and 2008 the Maarsee was renatured and filled with water again. For this purpose, the Gussbach, which flows through the dry maar, had previously been dammed. Today the Eichholz Maar is a popular place for rare water birds and reptiles.


  • Coordinates: 50°12´48´´ N / 06°58´10´´ E
  • Altitude: 483 m above sea level Funnel diameter in E-W direction: approx. 125 m
  • Funnel diameter in N-S direction: approx. 115 m
  • Funnel depth: approx. 25 m
  • Maar lake size today: approx. 1 ha
  • Maar lake depth today approx. 2.20 m
  • Laacher See tephra drilled at a depth of 12 m means approx. 13,000 years, possibly even 100,000 years, as the other maars in this region probably date back to the Old Quaternary.

The basement here consists of Lower Devonian sandstones from the Klerf layers of the Lower Ems stage (370 million years). They are interpreted as Wadden Sea deposits. On the NW edge of the maar there are still remains of river deposits made from the Buntsandstein (around 210 million years ago).

Special features

In 2004, the Institute for Physical Geography at the University of Frankfurt drilled a core drilling around 25 meters deep in the center of the maar, which was still dry at the time. In this drill core, a sequence of ice age debris deposits and younger, warm age lake deposits were documented. These lake deposits, which are approximately 16 meters thick, demonstrate the secure existence of a maar lake over a longer period of time. In the Tranchot map from 1811 from this region, the Eichholz Maar is still referred to as the Gussweiher filled with water.
