Course of Avisio

The Avisio in Moena

The Avisio ( German outdated Laifserbach Ladin La Veisc) running close is a left tributary of the River Adige in northern Italy. At a length of 88 km, it flows through the north-eastern Trentino and a short distance one belonging to South Tyrol section. The Avisio springs from a glacier of the Marmolada above the Fedaia Pass ( 2057 m). Just below the pass his water to Fedaia reservoir (Lake Fedaia ) is dammed. Its course runs through the Val di Fassa, Val di Fiemme and the Cembra. It ends at Trent in the Adige. On the entire route to the mouth (192 m) he has thus overcome some 2000 meters in altitude and worked its way out of the glaciated mountain world of the Dolomites in the mild climate of the fruit and wine growing regions of Trentino.

Character of the river

The from the Fedaia reservoir ( frozen from the first frost on often until well into June ) out kicking Avisio is in the headwaters of a torrent ( torrente ). At about 10 km the Fassa Valley loses about 600 m altitude. Between Soraga and Moena to approximately 1,200 meters of Avisio is dammed for the second time to a 1 km long lake ( Lach de Soraga ).

In the lower reaches the river bed widens and branches several times between sandbanks and pebbles.

A third dam is located at 787 meters altitude in Val di Fiemme Cembra on Stramentizzo reservoir. This lake is in the attention of local politics and local interest groups for the repair of natural and environmental damage. To rapidly changing water levels, for which the ENEL is held responsible, have triggered landslides in the past that have led to siltation of the lake, in the past, the wastewater from the entire Avisiotal were initiated uncontrollably.

Landscapes on Avisio

The Fassa Valley (Val di Fassa ) is an alpine holiday destination for mountaineers and skiers. It is part of the Great Dolomite Road.

In the located in slightly deeper regions and gentle downward sliding Fiemme Valley (Val di Fiemme ), a mainly frequented in winter resort area, it still is the same valley of the river Avisio. The section from Moena therefore carries only one other ( Italian ) name because he, unlike the Ladin section on the upper reaches, was trentinisch, while the Val di Fassa belonged to the diocese of Brixen.

The lower reaches of the Avisio through the orchards and vineyards of Trentino Valle di Cembra, named after the largest community of this section. It is still dominated agrarian; also porphyry is degraded. Tourism developed behave; he rather focuses on the higher elevations of the side valleys ( Altopiani ).

The last section of the river to the mouth of Lavis is a biosphere reserve in the human disturbance ( excavation of sand from the river bed, military exercises, motocross, hunting, sheep ) are prohibited. The aim of conservationists is to secure the habitat of the native amphibians and rare birds ( kingfisher, Yellow Wagtail, Dipper ) as well as winter quarters for migratory birds. Water scarcity in the lower reaches is in hot summers for the wildlife to the problem, especially since water is taken for energy and irrigation of orchards and vineyards.
