The Borna reservoir is a former open-cast mine near Borna south of Leipzig , which was converted into a flood retention basin from 1964 to 1980 . Normally, the storage facility is only partially filled; 46.10 million m³ are kept free as a flood protection area . The maximum depth with normal filling is 25 m, with high water up to 38 m. In the event of a flood, water from the Pleiße can be channeled through the Regis-Serbitz flood retention basin into the reservoir. The storage basin was commissioned in 1977. The Borna-West opencast mine had been shut down seven years earlier .
The dammed water is the Pleiße . The reservoir is also used to raise the low water level in the Pleiße, as well as for recreation (swimming, fishing, surfing) and fishing. The lake is an official Saxon and a certified EU bathing water and is colloquially called "Adria".
The dam is an earth dam made of cohesive earth without special sealing. Some embankments are still at risk of slipping, so entry is prohibited there. Due to the length of the crown of 6,500 m, the Borna reservoir is one of the largest reservoirs on earth . The places Blumroda, Hartmannsdorf, Görnitz and Alt- Deutzen were once located on the site of the opencast mine .
