Cranzahl Dam as seen from the Bärenstein

The natural origin of the brook is north of Kretscham-Rothensehma at about 805  m above sea level. NHN . The origin of the Red Sehma , also a tributary of the Sehma , is only a few meters away . While the Rote Sehma flows to the west and flows into the upper end of Neudorf , the Lampertsbach drains the northeastern area and only flows about 6 km downstream.

The natural Lambertsbach has a catchment area of only about 5.9 km² and at the dam only 4.5 km². For this reason, when the Cranzahl Dam was built between 1949 and 1952, plans were made to artificially enlarge the catchment area. The expansion took place between 1976 and 1982: with the 7.4 km long slope trench , the catchment area was enlarged by another 5.3 km². This ditch flows from the Sehma at about 835  m and runs in a loop on the northern slope of the Fichtelberg massif . Here he takes in some smaller streams from the right. It flows towards the natural source of the Lampertsbach.

Immediately at the beginning of the reservoir, the stream takes on the Moritzbach from the right. In the approximately 700 m long reservoir there is a second bypass with which pit water is brought in from the Unverhofft Glück pit near Bärenstein via a roughly 2.5 km long pipeline . This was built between 1988 and 1989. In the middle of the local area of ​​Cranzahl, the Lampertsbach flows into the Sehma.

The reservoir area is located in the Bärenstein nature reserve .
