The Dreiser Weiher near Dreis-Brück in the vicinity of Daun in the German state of Rhineland-Palatinate is a tub-shaped maar in the Eifel mountains. It is up to 1,360 metres long and 1,160 metres wide. It is the second largest maar in the Eifel.
The dry maar is located on a hillside and belongs to the Quaternary volcanoes of the West Eifel. It is surrounded by a crater rim of between 36 and 120 metres high. From the analysis of volcanic tufff, which were ejected from the maar during an eruption, and from geomagnetic measurements, five tuff fields and four volcanic centres on the edge of the bowl were identified. In the centre of the maar an eruption site was identified, hence the maar is probably an eruption funnel. The tuffs of the Dreiser Weiher lies above the depositions of the surrounding volcanoes, the maar is thus younger than the others. An exact date for the formation of the maars using pollen analysis could not be done for the Dreiser Weiher since there is no bog here.
