Bog water level
The water level of a raised bog is referred to as bog water level, which, similar to a soaked sponge, has its own water level above the groundwater level.
In contrast to a fen, a raised bog is not connected to the groundwater. It can arise in areas with a water-impermeable layer in a humid climate and grow from the center upwards, creating a clock-glass-shaped layer several meters high. The water level of a raised bog is then approximately at the level of the top layer. The actual groundwater level lies below the impermeable layer.
In contrast, fens emerged from the silting up of nutrient-rich lakes. They are supplied by the groundwater and running water and almost completely adapt to their surroundings. They therefore do not have their own water table.
