The Lohbach is a 4.5 kilometer long stream in the city of Innsbruck in Tyrol .

course

The Lohbach rises southwest below the Hartehof in Kranebitten . It flows slightly curved with a very slight gradient on the northern edge of the valley floor at the foot of the Nordkette in an  easterly direction through the districts of Hötting West  and Höttinger Au . He passes the Lohbach settlement built in 1934/35 and named after him . At the Vögelebichl it picks up the Höttinger Gießen (Gießenbach) from the right, occasionally the further course of the stream is also called that. This flows piped through the Höttinger Au and flows into the Inn below the university bridge .

Since the source and the tributaries have largely dried up or blocked, the stream is supplied with 15 l / s by a groundwater pump. Part of it is pumped into the pond in the Peerhofsiedlung , the overflow of which flows back into the Lohbach via a waterfall.

History and name

The Lohbach is probably an old Innarm, bounded by the floodplain flowed the Höttinger Au. In 1333 he was mentioned as Laa for the first time in a document, in the fishing book of Emperor Maximilian I from 1504 he is called Loh , in other sources also Stille Loo or Stilla . The name refers to a slowly flowing, marshy watercourse. Under Emperor Maximilian it was dammed up to a pleasure lake, filled with graylings , pills and gobies and used for fishing.

ecology

The western section of the Lohbach stream below the Peerhofsiedlung was renatured in 1988 and designed as a biotope. This was extended in 2006 and provides a habitat for different species such as grass snakes , dragonflies , grass frogs and toads . The fish in the Lohbach include rainbow trout , brown trout and char .
