The state of ground water level was determined in forested and cutover soils of central and northern Wisconsin by observations of open wells during the frost-free periods. In nonpodzolic, coarse, sandy soils, ground water possesses considerable mobility, and forest cover effected only a slight lowering of the water level, not exceeding 9 inches. The influence of forest cover was most pronounced in the middle of the growing season; from October to May the water table occupied nearly a horizontal position. In strongly podzolized, morainic soils, however, clear cutting of aspen stands produced an average rise of 14 inches, and converted a reasonably well-drained soil into a semiswamp. In the rainy spring and summer of 1952, this alteration of the ground water table was accompanied by increased run-off, erosion, and damages to roads.
