Dooser Wasserfall, Waterfall in Franconian Switzerland, Germany

The Dooser Waterfall forms where the Aufseß meets the Wiesent River, dropping about 2 meters (6 feet) over limestone rock faces. The cascade flows through natural stone layers before pooling in a basin below.

Until around 1850 the Aufseß plunged about four metres over a barrier of calcareous tuff just above its mouth. Farmers from Engelhardsberg, two kilometres south, then quarried the tuff for the vaulted ceilings of their cowsheds; a flood had already loosened the stone. The fall was thus halved to its present two metres. Jakob Reiselsberger, clerk at the Waischenfeld rent office, described the fall after a visit in 1820.

The name comes from the Aufseß, which once "roared down" (hinabtoste) into the Wiesent here, giving the falls their earlier name, Thooser Wasserfall or Toos. In 1820 Jakob Reiselsberger, a travel writer and clerk at the Waischenfeld rent office, visited and described the falls in his account.

The fall lies 200 metres south of the Doos hamlet, in the Naturpark Fränkische Schweiz – Frankenjura, about 5.5 km southwest of Waischenfeld. It is reached on foot; the Aufseß drops just before joining the Wiesent. The step is only two metres high, so the ground near the stream can be wet.

What visitors see today is only half the original height of this waterfall. The reduction happened gradually over decades as extraction activities changed the surrounding terrain.
