The spring has an average flow rate of 1200 l/sec, with peaks of up to 13,200 l/sec. The amount varies depending on the amount of precipitation. Due to the fast flow velocity of the water in the rock crevices (approx. 0.1 km/h), the karst spring reacts within a few hours to rainfall and snowmelt in the region.
Industrial history was written at the source of the Brenz. As early as the 16th century, the hammer mill was a milestone in iron processing in the upper Brenz Valley, and this is also where Germany's oldest iron industry originated. You can learn about this history on a tour of the historic part of Königsbronn around the source of the Brenz. If you prefer hiking, we recommend the 5-kilometer Brenzquellrunde trail to Lake Itzelberg, one of the day-long circular hiking trails on the Albschäferweg.
