Within Chequamegon-Nicolet National Forest. Forest County. T39N-R12E Sections 3-10, 17, 18. T40N-R12E, Sections 26, 33, 34, 35. 1,935 acres.



Haymeadow Flowage features a core of open and wooded wetland communities associated with the Haymeadow Creek and Flowage. Of note are old-growth hemlock-hardwood stands that are rare on this landtype on the Nicolet. There is good representation of the mature and seral stage forest communities that naturally occur on these rather dry and nutrient-poor habitat types. Wetlands range from open water and areas of cattails and floating sedge hummocks in the flowage proper, to black spruce muskeg-type bogs, mainly to the north of Haymeadow Creek. Several mixed conifer swamps with significant white-cedar components are scattered throughout the site, though none contain extensive areas of closed-canopy white-cedar. A high-quality open bog with two small bog lakes is located on the north edge of the complex. Several large red pine-dominated islands occur within the wetland matrix. Surrounding uplands are generally rolling pitted sandy outwash with some steep slopes bordering lowlands. A variety of communities occur, from stands of old growth hemlock-hardwoods to healthy younger mixed forests of red and white pine, red oak, red maple, and paper birch on the dryer, sandier soils. Most of the better upland stands are north of Haymeadow Creek, often in fairly narrow bands on steep slopes bordering lowlands. Ecological gradients are generally intact. Most upland stands have a mature pine component, often super-canopy white pine, with 26-30 inches in diameter fairly common in a few stands. Hemlock sizes are comparable, with one measured at 40 inches in diameter. The best stands exhibit a pronounced old-growth structure. Haymeadow Flowage is owned by the US Forest Service and was designated a State Natural Area in 2007.


Driving directions

From Eagle River, go east on State Highway 70 about 8 miles, then south on Military Road 3.4 miles, then east on Knapp Road 2.1 miles. Or continue south on Military Road another 1.6 miles, then south on Old Military Road 1.8 miles, then east on Hay Meadow Road 2.6 miles. The site lies east of the road. It is bordered by Sevenmile Lake and FR 2435 on west; FR 2179 on north and east. Several old logging roads and recreational trails provide access to various parts of the site.

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.

To create your own custom map where you can zoom to a specific location, please use the DNR's mapping application.


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.

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 detailed topographic map are useful tools for exploring larger SNAs.

Non-DNR lands

Entrance fees: For non-DNR-owned SNAs, we are unaware of any vehicle or admission fees. However, please contact the landowner for more information.

Hunting and trapping

This is a non-DNR owned SNA: Opportunities for hunting and trapping depend on the land owner. Please contact them directly to find out about their rules for hunting and trapping. You can find a link to other owner websites under the "Resources" heading above.
