Kahlquellen, Natural spring in Wiesener Forst, Germany.
Kahlquellen are two circular spring basins located in Wiesener Forst at about 290 meters elevation that continuously produce water. The system consists of two separately sized basins that connect and form the origin of a local river system.
In the Middle Ages, craftspeople used the water power of the springs for glassworks that developed nearby. One such facility was the former Epstein glassworks, which benefited from the reliable water supply.
The name Kahl derives from Germanic roots meaning bare or open, reflecting the exposed landscape surrounding the springs. You can observe how the clear water flows into the surrounding meadows and shapes the local environment.
The springs are located in an open forest area and are accessible year-round since they sit on level ground. The water is very cold and the ground around the basins can be muddy, especially after rain.
The water from Kahlquellen maintains a constant temperature of about 7 degrees Celsius throughout the year, regardless of season. This stable temperature creates ideal conditions for specialized water plants like watercress and spring moss that are otherwise rarely found in the region.
