Went for a walk in Rold Forest (Central Denmark) & found this interesting lake..
Rold Forest's springs are among the most water-rich in Northern Europe. The many springs in the area are due to the fact that the lime in the subsoil causes the groundwater to seep up. There is a rich fauna in the springs, even very special species that have traces all the way back to the Ice Age. The water flow of the springs is almost constant, and the water maintains a temperature of 7.5 degrees all year round.
The springs are protected, and it is forbidden to collect animals and plants from them.
