The Oberwillinger Spring is an artesian spring (often called Spring in Thuringia ) near the town of Oberwillingen, part of the town of Stadtilm, in the Thuringian Ilm district . It is an area natural monument .
geology
In the Oberwillinger Spring water from the Ilm emerges, which seeps 500 meters north of Griesheim into the karst subsoil of the Ilm-Saale-Platte , and feeds the Wipfra with an average discharge of 46 l / s . The water crosses the Eichenberg – Gotha – Saalfelder fault zone and the watershed between Ilm and Unstrut .
history
At the end of the 19th century, the city of Arnstadt intended to use the water from the spring to supply the city by building a high-pressure water pipe. This met with vigorous protest, especially from the mill owners on the lower Wipfra, who feared a decrease in the water flow of the river and thus problems with the mill operation. After eight years of discussion, these plans were finally dropped in 1898.
Inspired by the discussion, experiments were carried out in August 1899 with which the origin of the water of the Oberwillinger Springs could be proven through the coloring of the Ilm water.
