Freistadt basin
The Freistädter Becken is a small, tertiary basin landscape in the Mühlviertel in Upper Austria . The basin is dominated by the district capital Freistadt , which is also the namesake of the basin. The basin lies in the Austrian granite and gneiss highlands and is part of the Feldaist Basin , which represents the lowest transition from the Danube basin to the Vltava basin .
geography
The basin extends in the north to the northern settlement boundary of the city of Freistadt, in the west to the Jaunitzsenke , in the south to Pernau (municipality of Neumarkt im Mühlkreis ) and in the east to the slopes of the surrounding mountains of the Freiwald. The basin lies at a height of 530 m above sea level. A. up to 590 m above sea level A. In the southeast the Kefermarkt basin connects , which is separated by a 40 to 70 meter high step. The basin is one of the most striking basin landscapes in the Mühlviertel and has significant tertiary sediments that come from a former large river. The rest of the subsoil is made up of granite and gneiss . Above the granite base lies the Freistadt Tertiary, a 60-meter-thick sequence of sand and gravel with interposed clayey to silty layers.
The basin is a large and important groundwater reserve that is not yet used intensively. The municipality of Freistadt takes most of the drinking water it needs from this groundwater reservoir in the Galgenau waterworks ( Lage ). The municipality of Waldburg also uses this groundwater with the Jaunitztalsenke deep well ( Lage ). This sanctuary extends in the south from Kefermarkt over the Freistädter Basin and the Jaunitzsenke to the state border with the Czech Republic in the north.
climate
The Freistädter Basin differs climatically from the southern Mühlviertel and the Upper Austrian central area in that it has more snow and a somewhat lower frequency of fog and high fog. The precipitation is less than at a similar altitude on the northern edge of the Alps in Upper Austria. The basin rarely has snow maxima over 30 centimeters and is one of the regions with the lowest rainfall and the most continental climate in Upper Austria.
Waters
The most important flowing water is the Feldaist , which flows through the basin from north to south and drains it. A notable river is the Jaunitz , which flows into the Feldaist south of Freistadt. All other streams do not play a significant role. With the exception of smaller fish ponds, there are no still waters. The largest pond is the Weihteich near Galgenau (municipality of Freistadt) with an area of around two hectares.
traffic
For many centuries, the most important trade route from the Danube region to South Bohemia has led across the Freistadt Basin. Early Bronze Age finds in the Freistadt area, such as the find of a ridge ax near the Pregarten pond, bear witness to this traffic route.
In 1832 the Linz-Gmunden horse-drawn railway ran through the basin landscape, and there was a large station in Lest. The Summerau Railway has been running through the basin since 1872 . The Mühlviertler Straße (B 310) and in future the Mühlviertler Schnellstraße (from 2015) are the main thoroughfares in this basin.
