Soboth Reservoir
reservoir in Austria
Soboth reservoir (German: Stausee Soboth or Soboth See, Slovene: Jezero Sobote) is an artificial reservoir in Austria created in 1990 when an embankment dam on the Feistritz stream was created to power the Koralpe hydroelectric power plant. The artificial lake is located in the Koralpe mountain range, near the Soboth village, beside the road connecting Lavamünd and Graz, close to the Soboth Pass near the Slovenian-Austrian border. Its elevation is about 1080 m above sea level. Its natural drainage basin has an area of 29.7 km². The reservoir is around 2 km long and up to 500 m wide, has a surface area of 0.8 km2 and is up to 80 m deep. In summer, the lake is a popular place for swimming due to its clean water, cooler climate due to its high elevation, and natural surroundings consisting of spruce-covered hills.
Koralpe power plant
The Koralpe power plant was constructed between 1987 and 1991 as a passive storage power station. Between 2009 and 2011, the power plant was expanded into a pumped-storage power station.
The 50 MW station is located on the banks of the Drava River close to Lavamünd, at an elevation of 339 m above sea level. Water is routed from the reservoir to the power plant via a five-kilometer-long pressure tunnel and a three-kilometer-long pressure line.
This brief starts where responsible research should: with the source description of “Soboth Reservoir” as reservoir in Austria. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as reservoir in Austria. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Apr 10, 2026. The linked authority identifier is Q38251439. Authority coordinates are 46.685, 15.029. 1 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1990, 1080, 1987 and 1991.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
