During the construction parts of six villages were demolished and subsequently flooded. The village of Karlovec was completely flooded and ceased to exist. Today only Saint John Nepomucen Church and several other abandoned buildings remain at the reservoir's shore.[1] Villages of Dlouhá Stráň, Nová Pláň, Razová, Roudno and Leskovec nad Moravicí were also partially flooded and are today located on the shore of the reservoir.

The main use of the dam is to supply enough water in case of unfavorable conditions to the Kružberk dam, which supplies drinking water for the Ostrava agglomeration, and is located downstream on the Moravice River. It is also used to supply process water to the nearby towns and villages, generate electricity and subdue floods on the Moravice River.
