History and use
The name Lahnbach goes back to Bavarian - Tirolisch Lahn (avalanche).
Since the first permanent settlement of the area of today's St. Martin around 1500 BC BC on the east side of the mud-cone of the brook, the water requirement was met from the brook in the commercial as well as in the private sector. The Lahnbach was of greatest importance at the time of silver mining in Schwaz . The water was used for breweries , for fish farming , as an energy supplier for smelting and hammer mills as well as for mills.
Before the course was built, the Lahnbach repeatedly caused considerable damage on both sides of the rubble hill. Both people, livestock and buildings were affected by floods caused by melting snow and high summer weather . A bridge first mentioned in 1337 was also destroyed several times by floods. The historical floods entered in the city chronicle occurred in 1669, 1739, 1781 and 1807. The oldest evidence of eruptions dates back to the 14th century. The first protective structures were built in Schwaz as early as 1450.
Process water was also taken from the Lahnbach for the tobacco factory that was located in Schwaz from 1830 to 2005 . The management of the company initiated several protective and fortification measures to prevent possible damage.
In the course of rebuilding the stream in 1987, the bridge was concreted. In 2005 and 2017, the last temporary constructions were carried out on the middle lower reaches and existing sockets were renovated.
