Wisconsin State Natural Areas Program Mud Lake Bog (No. 141)

Overview

Location

Waupaca County. T25N-R12E, Section 18. 156 acres.

Description

Description

Mud Lake Bog features 30-acre undisturbed and undeveloped alkaline bog lake surrounded by a large northern mesic forest. The shallow, muck bottom lake lies in a well-defined basin and is fed by springs with an east side outlet leading to the Little Wolf River one mile to the south. Yellow and white water-lilies occur across the open water and a fringe zone of quaking sedge mat is best developed on the northwest corner of the lake. Behind the narrow mat is a more stabilized bog zone containing black spruce and tamarack with a sphagnum and ericaceous understory including leather-leaf and bog-rosemary. Some white pine is also present. An abrupt 15-foot rise marks the boundary between the bog and surrounding second growth northern mesic forest, which affords excellent protection to the lake and wetland. Mallards and blue-winged teal nest in the area while other migrating waterfowl use the area for resting. Mud Lake Bog is owned by the DNR and was designated a State Natural Area in 1977.

Access

Driving directions

From the intersection of County Highways C and G in Big Falls, go west on C about 3 miles, then north on County J 1.25 miles, then west on Mud Lake Road 1.9 miles to a parking area east of the road. Walk southeast through the woods into the bog.

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.

Objectives

Site objectives

Manage the site as an aquatic and a northern mesic forest reserve, and as an ecological reference area. Natural processes will determine the structure of the native communities represented here.

Management approach

Native species are managed passively, which allows nature to determine the ecological characteristics of the site. Exceptions include control of invasive plants and animals, maintenance of existing facilities, and access to suppress fires. Salvage of trees after a major wind event is not considered compatible with management objectives.

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
  • Drone use, unless authorized by a SNA research permit
  • 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]
