The Rotmoosache below the Schönwieshütte

The Rotmoosache is a glacier stream in the Ötztal Alps in Tyrol .

Run and landscape

The Rotmoosache is fed by the Rotmoos- and Wasserfallferner . It flows in a north-westerly direction through the relatively flat Rotmoostal . Through constant dynamic transformations, it has created a streambed up to 50 m wide. Especially in summer it receives numerous tributaries from the left from meltwater from the Hangererferner . Below the Schönwieshütte it turns to the north and flows through a steep, deeply cut gorge before flowing into the Gurgler Ache from the right . It has an average gradient of 7.2%.

Catchment area and water supply

The natural catchment area of the Rotmoosache is 11.8 km², of which around 4.1 km² (35%) are glaciated. The highest point in the catchment area is the Mittlere Seelenkogel at 3424  m above sea level. A.

The Rotmoosache has a runoff regime that is typical of a glacier creek with a water flow that fluctuates strongly with the year and time of day. The highest discharges occur in the summer months from June to August with discharge peaks of 2.5 m³ / s.

ecology

The ecological conditions are characterized by meltwater with its large fluctuations, low temperature (0 to 6 ° C) and low nutrient concentration. As a result, the Rotmoosache, like other glacier streams, has a species-poor fauna that is specially adapted to the extreme environmental conditions. These include the larvae of mayflies , stone flies , caddis flies and mosquitoes that live in the water . The alpine vortex worm can be found in the source area, and small crustaceans of the order Harpacticoida in more rapidly flowing sections .
