The Seebach or Obernberger Seebach is a stream in Tyrol with a length of around 12 km. It rises in the Stubai Alps on the main Alpine ridge southwest of the Brenner Pass . Initially it flows north, flows through the Obernberger See and then turns to the northeast. The brook flows through the Obernberger Tal , passes the town of Obernberg am Brenner and flows into the Sill near Gries am Brenner . For the first 5 km from the source to Obernberg, the stream has an average gradient of around 10%. The valley floor around Obernberg is relatively flat, only at the end of the valley does the brook drop steeply back to the Wipptal in a narrow Kerbtal valley .
The mean discharge at the Gries am Brenner gauge, 60 m above the mouth, is 1.9 m³ / s, which corresponds to a discharge of 32.6 l / s · km². The stream has a nival flow regime with moderate amplitude. The maximum discharge in June is a good five times the minimum in February. In the past, the stream was feared because of flooding , but it was straightened in dangerous places, but its natural surroundings were only slightly changed.
The Obernberger Seebach supplies Obernberg and the surrounding area with drinking water. From the wider middle reaches numerous fish such as B. Rainbow trout and minnows . The water quality class is consistently level I.
The water power of the creek has been used for many centuries, as evidenced by several old mills in Obernberg (Fradermühle, Michelsmühle, Alte Kirchensäge). There are two power plants in Vinaders and Gries that together generate around 8 GWh of electricity per year.
