Together with the Achental valley it parts theKarwendel mountain range in the west from theBrandenberg Alps in the east.Water quality is near drinking water, with sight up to 10 m below the surface. An alpine lake, water temperature is accordingly low, rarely above 20 °C. Its size and wind conditions make it suitable for
surfing .Eben am Achensee ,Achenkirch , andPertisau are municipalities on the lake.History
The city of
Innsbruck bought the lake in 1919 from theSt. Georgenberg-Fiecht Abbey , who had received it from the rulers ofSchlitters around 1120.Powerplant
Since 1924 the Achensee is managed by the Tiroler Wasserkraft AG (TIWAG), which was founded for this purpose.
Originally, its only outflow was the "Achen Bach" feeding the
Isar . Since 1927, when a powerplant inJenbach was finished, it primarily feeds theInn , at a level difference of 380 m below. Eightpelton wheel s at 500 rpm produce a total of 96 MW.In winter the level of the lake is lowered by up to 6 metres, accordingly the size of the lake keeps changing. At maximum level the reservoir can store 66 million m³ of water.
Tourism
When the
Unterinntalbahn railway was finished in 1859, tourism started to flourish. In order to make the abbey profit, the firststeamboat "St. Josef" was acquired in 1887.cite web | title=Die Flotte der Achenseeschiffahrt|publisher=Tirol-Schiffahrt|url=http://www.tirol-schiffahrt.at/start.php?t=0&m=2| accessdate=2008-08-06|language=German] Furthermore the construction of the 7 km longAchenseebahn narrow gaugerack railway was initiated, which went into service in 1889 betweenJenbach and "Seespitz". The same year, on July 21 a second steamboat, the "St. Benedikt" went into service. In 1890 the two boats with a capacity of 320 seats transported about 30,000 persons.In 1911 a third scheduled boat, the "Stella Maris" went into service. It was the first passenger boat on a lake in the Danubian monarchy originally equipped with a
diesel engine. The boat was designed for 400 passengers, and featured a particularly silent engine at low rpm, similar to those that later were used in the submarines of World War I.However, the "Stella Maris" was difficult to manoeuvre. When the lake was bought by the city of Innsbruck in 1919, the boat was renamed into "Stadt Innsbruck". In 1925 a motorboat named "Tirol" was acquired, and in 1927 for the first time more than 100,000 persons were transported.
In 1959 the "St. Benedikt" was replaced with a modern ship of the same name with a diesel engine. In 1971 the "Tirol" was replaced with a larger "Tirol II" for 40 passengers. In 1994 the "MS Tirol" went into service, replacing the "Stadt Innsbruck", and in August 2007 the "MS Stadt Innsbruck" replaced the "St. Benedikt".
