The Itz is a right tributary of the Main in southern Thuringia and Upper Franconia . According to the Bavarian Water Act (BayWG), it is a first-order body of water .

geography

The Itztal lies in the sandstone Keuper , Rhät , Lias and Dogger and, together with the surrounding hills, forms the Itz-Baunach hill country of the south-west German step country . The river is deeply deepened into the rock, its valley floor falls from 673  m above sea level. NN at 438 m to 235  m above sea level. NN . The meadow landscape is a cultural landscape in which the grassland dominates and which shapes the image of the Upper Mainland. The Itztal between Coburg and Baunach (14.5 km² FFH area ) as well as the Itz- Baunach -Aue with an area of ​​123 km² are specially protected landscape protection areas that are characterized by regular flooding. Meadows with rare and threatened species are characteristic of them . In the case of the animals, there are beavers , bullheads , light blue-colored buttonheads and dark blue-colored buttonheads , while the plants are alder and ash species . Almost a quarter of the floodplains are under nature protection .

River course

The river is about 80 kilometers long and has a 1029 square kilometers catchment area. It rises northeast of Eisfeld in the Thuringian Slate Mountains at 673  m above sea level. NN at the foot of the Bleßberg in Stelzen in the Hildburghausen district .

The town of Schalkau is located on the river in the upper Itztal . Immediately after the state border, it is dammed up to the Froschgrundsee in Bavaria to protect against flooding .
