The Obernberger Seebach, formerly called Obernberger Ache, is a river in Tyrol, Austria, a tributary of the Sill.
The Obernberger Seebach originates south-west of the Brenner[2] in the Stubai Alps and takes a north-east route to its mouth. On its course, it flows through Lake Obernberg.[3] In the middle of the valley the river passes through the village of Obernberg am Brenner. It discharges into the Sill at Gries am Brenner.[4]
From the spring to the junction with the Sill it falls more than 200 metres (660 ft) in a V-shaped valley. It provides the village with drinking water thanks to its Grade A quality. In the lower course live fishes such as rainbow trout and common minnow.
Even though the river is tiny, it has a high flow volume (approximately 10–15 m3/s (350–530 cu ft/s)). It was quite feared in the past because of its high water. It was mitigated at dangerous points, nevertheless its natural environment is fairly unchanged.
