The conditions described above have also led to the formation of a great number of wetlands, that are frequently linked to spring horizons and into which groundwater reaches the surface again. As a result, bogs, bog lakes and other small lakes, the so-called "woogs" are typical of the Palatine Forest, albeit the majority of "woogs" do not have a natural origin. They were more often artificially laid out by the impoundment of streams and were used as stages and reservoirs for timber rafting. However, the area covered by all the lakes and "woogs" in the Palatine Forest is not significant. The best known are the Gelterswoog on the northwestern edge, the Clausensee in the southwest and the Eiswoog in the northeast.
