Sohlberg Silver Lake features a small seepage lake nestled in a landscape of undulating topography with low wooded hills and scattered open bogs and tamarack swamps. Situated in the bed of now extinct Glacial Lake Wisconsin, the shallow lake has very soft, alkaline water and is moderately transparent. The fluctuating shoreline is dependent upon the local water table and the lake occupies anywhere from 7 to 16 acres depending on annual precipitation. These seasonal and yearly fluctuations maintain the sandy and muck shores in a relatively open condition that harbor several rare plants more commonly found along the Atlantic coastal plain: cross milkwort (Polygala cruciata), Virginia meadow beauty (Rhexia virginica), and reticulated nut-rush (Scleria reticularis). On the sandy shores and mud flats occur other uncommon species including autumn sedge, golden-pert, beak rushes, lowland rotala, and yellow-eyed-grass. On the adjacent uplands grows an even-aged dry forest of scrubby oak and jack pine while surrounding lowlands contain a sphagnum moss and sedge bog with cotton grass and leather-leaf and a tamarack swamp forest with huckleberry and low-bush blueberry. Bird use is varied and dependent upon the local water level. While the surrounding uplands attract many breeding birds, migratory bird use by species such as sandpipers and other shorebirds varies seasonally with the amount of exposed mudflats available for foraging. Sohlberg Silver Lake is owned by the DNR and was designated a State Natural Area in 1980.
