The Spullersee is an originally natural high mountain lake in Vorarlberg . It was dammed from 1919 to 1925 by the Austrian Federal Railways on the occasion of the electrification of the Arlbergbahn and has been used to generate energy ever since .
geography
It is located in the Lechquellen Mountains ( northern Limestone Alps ) between the Klostertal and a foothill of the Lech Valley on the Rhine-Danube watershed . The lake, which previously drained to the south, into the Alfenz and thus to the Rhine, is now dammed by a wall towards the south and towards the north. The Spullerbach , which is a source of the Lech , rises north of the lake . To increase the inflow, a transition from Lake Zürser to Spullersee was driven through the mountains. The lake content continues to flow into the Alfenz via the Spullersee power plant.
The lake is a popular fishing lake in summer. He is known for his trout . Fishing is not possible between December and February due to icing.
Spullersee storage power plant
Reservoirs serve to retain water at high altitudes. As a result, the flood peaks can be dampened and flood damage limited. The Spullersee serves as a reservoir for the hydroelectric power station of the same name in Wald am Arlberg , which generates traction current.
The Spullersee power plant was built with great manual labor and hardship. As a result, there were strikes during construction in 1920, 1921, 1922 and 1923 for better working conditions and higher wages.
Three aboveground penstock pipelines with a diameter of 950 mm to 650 mm, which come out of the ground in the area of Graf tip lead storage power plant the Spullersee water as power descent with a length of 1.395 meters and a pressure of up to 811 meters powerhouse Spullersee to . The expansion water volume is 6 m³ / s at 36 MW and an annual production of 46.7 GWh. The storage target is 1,829.6 m and the power house is 1,019.0 m. Between 2002 and 2005, the dam was rehabilitated , during which around three quarters of the air sides of the concrete gravity dams disappeared behind a natural fill, which was then conquered by the alpine flora . This was an essential contribution to landscape protection.
Between 2012 and 2014 an additional pipeline to expand the catchment area should be built. The Vorarlberg alpine community Pazüel-Tritt decided unanimously on March 24, 2011 not to surrender its water rights for an expansion of the ÖBB power station Spullersee. Previously, in 2008, alpine owners from the Zürs area had already spoken out against diverting the water, which normally flows into the Lech and thus into the Danube, into the Spullersee. ÖBB calmly examined all options and rejected the plans in 2015.
By 2021, the almost 100-year-old power plant and pressure pipeline are to be renovated by more than 31 million euros and brought up to the current state of the art. The penstocks previously laid above ground will be replaced by an underground one. No performance increase is planned as a result of the renovation. For this purpose, the lake was emptied via the bottom outlet in January 2020.
