The valley reservoir in Lučina near Žermanice for the supply of operating water to the Ostrava industry was built between 1951 and 1957.

The insufficient water content of Lučina itself required the construction of a water transfer from the Morávka River, which was completed in 1959.

The system of water management works in the Morávka and Lučina river basins was supplemented by a later built reservoir in Morávka.

The purpose of the Žermanice waterworks is to supply Nová Huta as in Ostrava and Biocel Paskov as with process water, as well as to improve flows in the flow below the dam and to produce electricity. The reservoir and its surroundings are a popular recreational place.

The concrete gravity dam with a total concrete volume of 116,600 m 3 is established in an environment of complex geological conditions with the necessary structural modifications of the substructure and subsoil. Regular measurements of dam displacements and subsoil consolidation form an essential part of caring for the safe operation of a waterworks.
