Overview

Location

Adams County. T16N-R5E, Sections 4, 9. T17N-R5E, Section 33. 308 acres.

Description

Description

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. 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.

Maps

The DNR's state natural areas program is comprised of lands owned by the state, private conservation organizations, municipalities, other governmental agencies, educational institutions and private individuals. While the majority of SNAs are open to the public, access may vary according to individual ownership policies. Public use restrictions may apply due to public safety, or to protect endangered or threatened species or unique natural features. Lands may be temporarily closed due to specific management activities. Users are encouraged to contact the landowner for more specific details.

The data shown on these maps have been obtained from various sources, and are of varying age, reliability, and resolution. The data may contain errors or omissions and should not be interpreted as a legal representation of legal ownership boundaries.

Recreation

Very few State Natural Areas have public facilities, but nearly all are open for a variety of recreational activities as indicated below. Generally, there are no picnic areas, restrooms, or other developments. Parking lots or designated parking areas are noted on individual SNA pages and maps. Trails, if present, are typically undesignated footpaths. If a developed trail is present, it will normally be noted on the SNA map and/or under the "Access" tab. A compass and topographic map or a GPS unit are useful tools for exploring larger, isolated SNAs.

Allowable activities

In general, the activities listed below are allowed on all DNR-owned SNA lands. Exceptions to this list of public uses, such as SNAs closed to hunting, are noted under the "Access" tab above and posted with signs on site.

  • Hiking
  • Fishing
  • Cross country skiing
  • Hunting
  • Trapping

Prohibited activities

  • Camping and campfires
  • Collecting of animals (other than legally harvested species), non-edible fungi, rocks, minerals, fossils, archaeological artifacts, soil, downed wood, or any other natural material, alive or dead. Collecting for scientific research requires a permit issued by the DNR
  • Collecting of plants including seeds, roots or other non-edible parts of herbaceous plants such as wildflowers or grasses
  • Geocaching
  • Horseback riding
  • Rock climbing
  • Vehicles, including bicycles, ATVs, aircraft, and snowmobiles except on trails and roadways designated for their use

For rules governing state-owned SNAs and other state lands, please consult Chapter NR 45 Wis. Admin. Code [exit DNR]
