Lázbérc Reservoir, A water reservoir in Hungary.

Lázbérc Reservoir is a Y-shaped artificial lake of 77 hectares in the Uppony Hills, between Uppony and Dédestapolcsány in Borsod-Abaúj-Zemplén County, Hungary. It was formed by damming the Bán stream; its 19-metre-high, 250-metre-long earth dam has a water-side face covered with 120,000 concrete slabs. The reservoir holds 6.2 million cubic metres of water and lies at 200 metres above sea level.

Construction of the reservoir began in 1967 with the damming of the Bán-patak. The 19-metre-high, 250-metre-long earth dam required moving 250,000 cubic metres of soil, and its water-side face was covered with 120,000 concrete slabs. The 22-metre intake tower was installed and filling took place in 1969, with regular operation from 1970. The new 4.5-kilometre road over the ridge between Dédestapolcsány and Bánhorváti was finished by summer 1969 after the old valley road was submerged.

The reservoir is accessible by road and offers spots for viewing and relaxing along the shoreline. Visitors should know that some areas may be restricted by private property or safety regulations.
