The Margaritze reservoir is located at the foot of the Pasterze and Grossglockner in the Hohe Tauern in Carinthia .
The reservoir at 2000 m altitude and with a volume of up to 3.2 million m³ of water belongs to the upper stage of the Kaprun power plant and was completed in 1953. It is formed by the Möllsperre and the slightly curved Margaritzensperre and stores the runoff of the Pasterzen glacier and the Leiterbach (with a tunnel). The water is led through the 11.6 km long Möll transfer tunnel through the Tauern main ridge to the Möll pumping station.
Margaritze storage facility
The Margaritze is a valley basin that was formed by the Pasterze, and through the decline of which after the beginning of the last century it became ice-free and formed the source basin of the Möll . It is located below the Glocknerhaus on Gletscherstraße , the detour of the Großglockner High Alpine Road to Franz-Josephs-Höhe , and is now about 2 km below the end of the Pasterze.
Two dams , the Möllsperre (56 m statically effective height) and the slightly curved Margaritzensperre (39 m statically effective height), form a reservoir . It is around 200 m long, around 800 m wide and has a useful capacity of 3.2 million m³ of water. It serves as a weekly storage facility and collects the melt water from the Pasterzen glacier, which naturally drains via the Möll into the Drau . The congestion target is at 2,036 m above sea level , the lowering target at 1,980 m. When the storage target is lowered to the lower target, the Margaritzenspeicher pours 3.2 million m³ of water and thus contributes 8.3 GWh to the generation of electricity, with an annual working capacity of 152 GWh.
In the 1970s, the Pasterze reached as far as the Pasterzengrund, which stretches a few hundred meters above the Margaritze and at the time formed a glacier lake , the Sandersee . Until the 1990s, this lake held back the released glacial sediments, but is now completely silted up, which means that an average of 40,000 m³ / year of sediment is now deposited in the Margaritze reservoir. A storage flushing is not possible at the lake, the bottom outlet is kept free by means of a suction dredger by relocating it to the flat areas, a Margaritze-Naßfeld desanding plant is being planned.
Möll transfer tunnel
The water is directed or pumped through the 11.6 km long Möll transfer tunnel into the Mooserboden reservoir in the Kaprun Valley , depending on its water level. It tunnels through the watershed of the main Alpine ridge between the Drava (near Osijek / Croatia in the Danube ) and Salzach / Inn (near Passau in the Danube). This allows precipitation on both sides of the main water and weather divide of the Alps to be recorded.
The tunnel runs from the Margaritze exactly northwards, under the western flank of the Fuscherkarkopf in the Käfertal , and slightly westwards near the Schwarzenberger Hütte and under the Hinteren Bratschenkopf in the Kapruner Tal. The Möllpumpwerk located underground beneath the Mooser soil at the pressure tunnel upper stage , which is below the Limbergsperre of the Drossen of Mooserboden to the power house upper memory Wasserfallboden leads, roughly where the water lock below the Heinrich Schwaiger house at Wiesbachhorn located.
