Hanson Lake Wetlands features a diverse mosaic of representative wetland communities and associated aquatic features. The complex, located west of the North Fork of the Flambeau River occurs on hilly pitted outwash deposits and includes a cluster of small, shallow, soft-water seepage lakes and ponds with widely fluctuating shorelines. Hanson Lake, a 13-acre designated Wild Lake, is completely undeveloped with no improved access. The lake contains an abundance of aquatic vegetation with several floating, semi-detached leatherleaf-dominated islands. The lake is fringed with margins of zoned vegetation due to the changes in water levels.

The uppermost zone supports blue joint grass and steeplebush while the lower zones contain leather-leaf, three-way sedge, arrow-root, nodding beggar-ticks, smartweeds, rattlesnake manna grass, water-horehound, and numerous sedges. To the south, is a black spruce swamp surrounding a small bog lake dominated by black spruce and tamarack over thick sphagnum hummocks. Common understory species include bog rosemary, leatherleaf, Labrador-tea, creeping snowberry, Canada blueberry, cinnamon fern, and three-leaf Solomon's seal. On a narrow mat near the pond's edge are pitcher plants, white beak rush, tussock cotton grass, muck sedge, and boreal bog sedge. To the west is a small, open bog situated in a seepage basin and fringed by a northern sedge meadow. The wetland complex and surrounding uplands provide excellent habitats for a diversity of birds and aquatic insects. Bird species noted include black-throated green warbler, least flycatcher, ovenbird, northern parula, broad-winged hawk, gray jay, hermit thrush, white-throated sparrow, Nashville warbler, and yellow-rumped warbler. Hanson Lake Wetlands is owned by the DNR and was designated a State Natural Area in 2010.

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. If a developed trail is present, it will normally be noted on the SNA map and/or under the Maps tab. A compass and topographic map or a GPS unit are useful tools for exploring larger, isolated SNAs.

The good majority of SNAs are isolated and have few or no facilities. Some SNAs have vehicle access lanes or parking lots, but their accessibility may vary depending on weather conditions. Parking lots and lanes are not plowed during winter. Hiking trails may be nonexistent or consist of undeveloped footpaths. A GPS unit or compass and a detailed topographic map are useful tools for exploring larger SNAs.

Entrance fees: Except for Parfrey's Glen, the Cambrian Outlook in the Dells of the Wisconsin River, SNAs within State Parks and some within State Forests, all other DNR-owned SNAs do not have any admission fees. For more information, see Wis. Admin. Code NR 45 [exit DNR]. For non-DNR-owned SNAs, we are unaware of any vehicle or admission fees. However, please contact the landowner for more information.

Allowable activities: DNR-owned land

The activities listed below are generally allowed on all DNR-owned SNA lands. Exceptions to this list of public uses, such as SNAs closed to hunting, are noted above and posted with signs on the property site.

Prohibited activities: all SNAs

Although a handful of sites allow activities like primitive camping (e.g. Lower Chippewa River on sand bars) or horseback riding (e.g. S. Kettle Moraine), the activities listed below are generally prohibited on DNR-owned SNAs.

  • 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
  • Drones: Flying-related activities, including the use of drones, hang-gliders and model airplanes, are prohibited. Permission may be issued by the SNA Program for the use of drones for educational or research purposes
  • 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].

Driving directions

From the Oxbo bridge at Highway 80, go south on Payne Farm Road for 3 miles, then continue walking south for 1.5 miles, then southeast 0.25 miles to the wetland complex.

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.
