The Albstausee or the Alb basin (Albtalsperre) is a storage reservoir in the Alb valley near St. Blasien in the southern Black Forest . It is part of the Schluchseewerk AG Laufenburg pump storage network and is located between Schluchsee and the Rhine near Waldshut. The barrier structure is a 28 m high gravity dam .
The Albstausee is located in the Alb valley at approx. 737 m above sea level. NN. The next place is the city of St. Blasien (760 m above sea level), whose industrial area in the south extends to the end of the reservoir.
The reservoir lies for the most part in the area of the city of St. Blasien, a small part of the lake in the west and almost the entire dam wall are in the area of the municipality of Dachsberg .
The state road 154 running through the Albtal, the Albtalstraße , leads from Albbruck am Rhein through the Albtal to St. Blasien and runs about 1.4 km along the east bank before it reaches the city.
In the Schluchseewerke network, the reservoir, in addition to the Mettmastausee in the Mettma valley , forms one of the two side arms in connection with the Schwarzabruck reservoir (lower basin for the power plant of the upper level or upper basin of the intermediate level ) in the Schwarzatal .
In the Alb basin, the sediments were not placed on landfills when the reservoir was rehabilitated, but instead poured into a bird island using the flushing process.
