The water structure of Ružín

The Ružín Water Structure is a system of water works (VD) of Ružín I and Ružín II., Built on the Hornád River, above Košice, from 1962 to 1972.
It is located in the northeastern part of the Slovenské Rudohorie, where the River Hornád flows through a deep and narrow valley between the steep slopes of Volovské Hills and Čierna hora.
The main purpose of the hydroelectric system is to provide water for the industry in the Košice region, to improve flow rates in order to improve water purity in the flow, electricity generation and partial flood protection of the area under the dam. The reservoir is also used for recreational purposes.
The water work is administered by the Slovak State Water Management Company.
