The Leutascher Ache in Leutaschtal

The Leutascher Ache, called the upper reaches Gaistalbach, in the Bavarian section Leutasch, is a left tributary of the Isar River, which runs in Tyrol and to a lesser extent in Bavaria.

Course

The Leutascher Ache springs north of hedgehog head width and head in Mieminger Mountains in the municipality of Ehrwald and runs at first towards the north. After approximately one kilometer, it absorbs the water from the Igelsee and flows eastwards through the Gaistal between Wettersteingebirge and Mieminger through (on Mieminger and Wildermieminger municipality ). In Leutasch she turns to the northeast, flows through the Leutaschtal, a high valley, and empties after Leutaschklamm ( Spirit Gorge ) in Mittenwald ( Bavaria) at the river Isar.

Water management

The average discharge at the level gorge is 1.40 m³ / s, which corresponds to a runoff of 31.1 l / s · km ² equivalent ( series 1984-2009 ). The Leutascher Ache has a nivales flow regime, as is typical for a mountain glacier without influence. The average discharge is in the water-rich month of May (3.02 m³ / s) more than seven times higher than in the most arid month of February (0.41 m³ / s).

Ecology

The passage of Leutascher Ache is relatively close to nature, with ecological state except in the immediate settlement areas rated as very good to good. The sole is not built outside the settlement areas, the banks are selective, installed throughout the settlement area. The Leutascher Ache is one of the cleanest rivers in Tyrol, it has water quality class I in the entire course on.
