The water reservoir Nová Bystrica was built between 1983 and 1989. It is located on the river Bystrica, in the area below the confluence of the brooks of Harvelka, Stanov potok and Riečnica. “Cholvárkami”. Only the Catholic church from the village of Riečnica remained from the original development. It serves primarily as a source of raw drinking water, which is directed to the treatment plant and from there it is distributed to the districts of Žilina and Čadca as drinking water, further it serves to contain the flood wave and utilizes its hydro-energy potential.
Hydrotechnical data: the height of the dam above the floodplain 32,50 m dam length in crown 390,00 m min. operating level 361.00 m n. m. max. operating level 377.25 m n. m. max. holiday level 378.80 m n. m. total tank volume 8 431 443 м3
Water construction Drahovce – Madunice also known as Sĺňava Reservoir. The Drahovce – Madunice Water Structure is a multipurpose water works, which uses the Váh section between Piešťany and Hlohovec, was built between 1956 – 1959. The commencement of permanent operation was in 1960. The primary purpose of the water construction is to ensure sufficient water for the Jaslovské Bohunice nuclear power plant and water abstraction for irrigation. Secondary purposes include recreation, water sports and fishing, as well as environmental protection and enhancement. Drahovce weir is situated on the Váh river in rkm 113.43. The total length of the gate is 132.0 m, it consists of six weir fields covered by double-segment hooks with a width of 16.0 m and a height of 7.8 m with a total capacity of 3400 m3 · s − 1 The restraint is situated on a plane and is formed by a weir and a system of two perimeter dams. The flooded water creates a maximum flooded area of 4.3 km² with a total tank volume of 12.5 mil. m3
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, […]
Water structure Krpeľany was put into operation 5.12.1961 and is part of the so-called. Hornovážská cascade, which consists of 3 stages: Krpeľany – Sučany – Lipovec. The purpose of the water construction is to use the energy of the river Vah to produce electricity. energy in the section between Kraľovany and Vrútky, local navigation and partial reduction of large water flows in the river Váh and the adjacent section by the capacity of the waterworks. For energy use is taken by water power plant Krpeľany max. 210 m3.s-1. The Krpeľany stage consists of the following structures: earth dam, weir, power plant, reactive weir, small hydroelectric power plant, waste channel, treatment of the Váh in the reservoir and under the water works, 110 kV substation, pumping station Kraľovany. The dam, weir and power plant cross the valley of the Váh river, which gives way to water and creates a reservoir with a flooded area of 1.26 km2, the length of the backwater is 5990 m, max. the flood area is 510.0 m wide. Total tank volume (projected state) 8.333 mil. m3 is reduced to 3,500 mil.m3 due to sediment deposition (focus in 1977).
Zemplínska Šrava in the past called Zemplínska Sĺňava was built in 1961 – 1965 The primary purpose of the dam was to protect against flooding and irrigation of agricultural land, while recreation was originally considered only marginally. The dam is also a dry reservoir (so-called polder) Beša. Šírava is used for recreational purposes, sailing, flood protection, irrigation of the East Slovak Lowland and as a water source for industry (Vojany thermal power plant). The eastern part of the dam between the villages of Kusin, Hnojne and Jovsa is overgrown, which suits waterfowl. This area is reserved by ornithologists as a protected study area, a protected area was established here (see: CHA Zemplínska šírava) declared in 1968 on an area of 622 ha, the purpose of which is to protect the ornithological locality in the eastern part of the artificial water reservoir. of which 37 rare. Before the construction of the water reservoir there was no village on its surface. The space between the future resorts of Horka and Bear Mountain was used in 1939 by the German Luftwaffe to build a makeshift airport without a paved runway. The airport was used in the attack on Poland in the early World […]
