The mill pond or large mill pond is a karst spring near Osterode am Harz in Lower Saxony .
location
The mill pond is located on the northeastern outskirts of Förste in a small park. It is the largest of 35 karst springs in the local area. The flowing stream of the springs flows over the salt ditch into the Alte Söse . The karst hiking trail that begins in Pölsfeld ends at the mill pond .
Data
The karst spring pours out an average of 380 liters of water per second. It used to drive several mills. The spring water of the pond has a low oxygen and high rock salt content of 3.6 grams per liter. Its low fluctuations in pouring point indicate a geologically very young age.

Use of the sources
The springs have been used balneologically since the 1960s . The chloridic waters are bottled for healing purposes , the others as mineral water ("Förster Grafenquelle"). The mineral water supply today comes from boreholes . These have also opened up highly salty water.
Origin of the water
The salt-laden water flowing in from the north in the depths under the Sösetal is forced to rise at a water-impermeable transverse fault . They preferentially loosened the rock cover in a weak zone and are now coming to light in forest areas. Contrasting water studies have shown that water also flows from the Beierstein depression into the springs from time to time.
