The Leutascher Ache in the Leutasch Valley |
The Leutascher Ache , in the upper reaches Gaistalbach , called Leutasch in the Bavarian section , is a left tributary of the Isar , which runs in Tyrol and to a small extent in Bavaria .
course
The Leutascher Ache rises north of Igelskopf and Breitenkopf in the Mieming Mountains in the municipality of Ehrwald and initially runs north. After about a kilometer, it absorbs the water from the Igelsee and flows east through the Gaistal , between the Wetterstein Mountains and the Mieminger Mountains (on the Mieminger and Wildermieminger municipal areas). At Leutasch it turns to the northeast, flows through the Leutasch valley , a high valley , and flows into the Isar after the Leutaschklamm (Geisterklamm) at Mittenwald ( Bavaria ).
Catchment area and water supply
The Leutascher Ache drains a catchment area of 110.85 km², the highest point in it is the Hochplattig at 2768 m above sea level. A.
The mean discharge at the Klamm gauge, 16.4 km above the mouth, is 1.40 m³ / s, which corresponds to a discharge rate of 31.1 l / s · km² (series 1984–2009). The Leutascher Ache has a pronounced moderate-nival discharge regime , as is typical for a mountain stream without the influence of glaciers. The mean discharge in the month with the most water in May (3.02 m³ / s) is more than seven times higher than in the month with the least water in February (0.41 m³ / s).
ecology
The course of the Leutascher Ache is relatively close to nature, its ecological condition is rated as very good to good, except in the immediate settlement areas. The bottom is not built up outside of the settlement areas, the banks are selectively built up throughout the settlement area. The Leutascher Ache is one of the cleanest rivers in Tyrol, it has water quality class I throughout .
history
The Leutascher Ache is documented early on. In 1177 it is mentioned in a traditional note in favor of the former Augustinian canons of Polling as "aqua que dicitur Livtaske" .
