The dam was based on sedimented shale and has an internal impervious core of organic clays (grass sods).

After removing 90 cm of the old dam crest, a metre-wide toe wall was integrated from the subgrade (Planum).

The Fürstenteich was first linked into the Lower Harz Pond and Ditch System in 1903/04, when the dam was raised for the first time.

The Kochsgraben was extended for the last time and now ended in the catchment area of the Teufelsteich, the Siebengrund bottom.

Now the Teufelsteich as well as the Fürstenteich and the Silberhütter Pochwerksteich were additionally supplied with water from the Lude stream and the Rödelbachgraben.

The pond may be reached from the neighbouring Teufelsteich over hiking trails and is used for water management, angling and recreation.
