System of water works Dobšiná
The system of water works consists of Palcmanská Maša – Vlčia Valley – Dobšiná. The first two were built between 1948 and 1954. The Dobšiná reservoir was created later, in 1957 – 1960, as a buffer reservoir below the Vlčá dolina valley in order to eliminate the fluctuations in the flows in the Dobšinský stream caused by the production of peak electricity. It is the first larger hydro-technical building in the east of Slovakia, on its contact with central Slovakia and it is situated in the western part of the Volovské Hills with water transfer from one catchment to another and from the Hornád catchment to the Slaná catchment.
The water work also serves the so-called indirect effect. From this point of view, the accumulation tank Palcmanská Maša fulfills aesthetic, landscape and recreational-tourist role. Despite the predominantly energetic importance of the waterworks, its flood protection function, which has gained its current significance in recent years of frequent and extreme floods, is not negligible.
The main objects of the system are the dam and accumulation tank Palcmanská Maša in Hnilec, the sampling object and pressure feeder, the lower reservoir created by the dam in Vlčina valley, high-pressure and low-pressure peak hydroelectric power plant and buffer reservoir on Dobšinský stream. PVC. Most of the system objects were built in. 1948 – 1956, with the exception of the dam reservoir Dobšiná, which was built in r. 1957 – 1960.
