The Wiesaz is the longest, right side opens out tributaries of Steinlach. It rises at an altitude of around 760 m above sea level. NN beneath the sun Buhler hamlet Genkingen in the Swabian Jura, a limestone mountain. The emerging spring water contains a lot of dissolved lime, which by pressure relief and by the removal of carbon dioxide by aquatic plants, mostly algae, fails. Thus several meters thick Kalktufflager have the upper Wiesaztal Approximately 7000 years ago formed until 1975 for the extraction of quarry stone ( travertine ) and lime sand were mined.
The Wiesaz flows through the Gönninger lakes that were created artificially in the context of restoration measures from the former Kalktuffsteinbrüchen, as well as by the places and Gönningen Bronnweiler, both districts of Reutlingen, Gomaringen and the settlement powder mill before moving to around 16.5 kilometers to 360 m above sea level. NN 27 opens into the Steinlach immediately after passing under the highway.
In Gomaringen the Wiesaz takes on the coming from Rahn mountain in the south Erdmann Bach. When Wiesazsägmühle the bung trench opens on the left side. The Wiesaz has no significant right-side tributaries. Together with the West of engaging in the escarpment of the Swabian Alb Öschenbach, a right side tributary of Steinlach that Wiesaz has the plateau between Schoenberg in the west and mountain cattle almost separated in the east of the plateau of the Jura. The thus created Ausliegerberg crowns the 869 -meter high Rossberg, one of the highest mountains of the central Swabian Alb.
In the course of Wiesaz there are several Mühlkanalabzweige and partially disused sawmill and flour mills, the tap the water all year round leading Bach. A power plant and a former sawmill in Gomaringen use to this day the water power of the stream. The Wiesaz also receives the sewage water treatment plant Genkinger the upper reaches.
The Wiesaz has between localities and between Bronnweiler and Gomaringen Gomaringen and the confluence with the Steinlach a naturally meandering watercourse with impact and Gleithangbereichen. It runs there in a wide flood plain. The waters edge is marked by a semi-natural floodplain gallery of silver willows, ash and alder forest, which is dominated by isolated hybrid poplars ( Populus × canadensis). Due to the intense low Lothar numerous gaps were torn in the closed trees. In the area of the former Kalktuffsteinbruchs the course of Wiesaz is straightened. There he is also bordered by a natural red-alder riparian forest.
There are paved bike trails almost the entire length of the source towards deep Wiesaztales. The Gönninger lakes are a recreation area with lawn and ample parking. However, they also provide habitat for numerous, some rare plant and animal species. There, for example stoneworts are detected. There are breeding places of Dipper and Little Grebe. The lake is also used by the water as bat foraging habitat.
