Wisconsin State Natural Areas Program Fountain Creek Wet Prairie (No. 100)



Within the Grand River Marsh Wildlife Area, Green Lake County. T14N-R11E, Section 8 and 17. 252 acres.



Fountain Creek Wet Prairie is a large wet, low prairie situated in the basin of the Grand River Marsh. The wet prairie, a rare community type in Wisconsin, is characterized prairie cord grass, bottle gentian, blue-joint grass, Kalm's brome, mountain mint, prairie blazing-star, marsh fern, and Michigan lily. Higher areas contain prairie drop-seed, marsh muhly, big and little blue-stem, and characteristic fen species such as shrubby cinquefoil, marsh fern, and boneset. Some of the more showy forbs include turtlehead, New England aster, sneezeweed, phlox, and wood lily. Because the area is located within the Grand River Marsh Wildlife Area, it is used by a large number of sandhill cranes, great blue herons, and geese. The wet prairie soils are easily compacted and vegetation fragile - please walk softly. Fountain Creek Wet Prairie is owned by the DNR and was designated a State Natural Area in 1972.

  • WDNR


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.


Site objectives

Manage the site as a wet prairie reserve, a wetland protection area, and an ecological reference area. Natural processes and prescribed fire will determine the structure of the prairie. Provide opportunities for research and education on the highest quality native prairies.

Management approach

The native prairie species are managed actively through tree/shrub control using tree harvest, brushing and especially fire to mimic natural disturbance patterns. Occasional fire-tolerant native trees and shrubs may be retained at low densities. The ecological characteristics of the site will be primarily shaped by an intensive fire management program. Other allowable activities include control of invasive plants and animals, augmentation of native prairie species after careful review, maintenance of existing facilities, and access to suppress wildfires.


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
