geography

course

The Zorge arises in Lower Saxony in the Harz Mountains and within the Harz Nature Park through the confluence of Wolfsbach and Sprakelbach in the village of Zorge in the middle of the upper part of the village at around 352  m above sea level. NHN . The Wolfsbach in turn has several source streams. The source of the Großer Wolfsbach has the longest flow path and is classified as the main source of the Zorge. It is just below 570  m above sea level. NHN at the sports field in Hohegeiß .

Initially the Zorge flows in a southerly direction and from around the Lower Saxony-Thuringia border into the southeast. In the Thuringian part of the Harz, it runs through the South Harz Nature Park . Here Ellrich , Woffleben and Cleysingen are on the river. On the southern edge of the nature park, the Zorge touches Niedersachswerfen , a district of Harztor . Then it flows through Nordhausen . After the city, the river passes Bielen and Windehausen .

A little more than 2 km behind Windehausen, the Zorge passes under the Halle – Hann railway line. Münden . Shortly afterwards, at 158.8  m above sea level, it flows into the Unstrut tributary Helme coming from the west or from the direction of Heringen . The estuary lies in the Kyffhäuser Nature Park .

Hydrology and water quality

Along with other rivers such as the Wieda , the source brooks of the Zorge drain one of the areas with the highest rainfall in the Harz Mountains. The amount of water supplied to the helmets was one of the reasons for the construction of the Kelbra dam on this river . In Thuringia the Zorge is  rated as “moderately polluted” ( water quality class 2). In the late summer of 2019, the river dried up completely due to the lack of precipitation from the south-eastern outskirts of Nordhausen to Bielen. Numerous fish as well as other organisms living in the water perished. The local fishing club rescued some animals from the remaining puddles.
