It was completed in 1699 and taken into service for mining operations in the Neudorf mining district. In 1963 the dam had to be repaired because the penstock had collapsed. In 1967 the dam was once again in operation. It has since been used for recreational purposes. There are bathing areas, a campsite and the Birnbaumteich Holiday Park (Ferienpark Birnbaumteich) by the reservoir.
In summer 2006 the dam itself was refurbished.
The Birnbaumteich is an earth-fill dam with an impervious core. In the older section the core consists of sods; the newer section around the penstock of concrete. The spillway on the right abutment consists of a pipe culvert with a diameter of 1 m. The headwater stream is known as the Birnbaumgraben or Bach vom Birnbaumteich ("Birnbaumteich brook").
