Huiras Lake

Ozaukee County. T12N-R21E, Section 9. 198 acres.



Huiras Lake features a 26-acre pristine, hardwater seepage lake with an undeveloped shoreline contained within a larger wooded matrix. Plant communities include dry-mesic forest, mixed conifer and hardwood swamp, and a relict kettle bog. Located within a lowland hardwood swamp of black ash, the open water of the bog is surrounded by a narrow band of sphagnum moss and cat-tails and grades into shrub-carr and a tamarack-white cedar swamp. Several white pines are present and poison sumac is scattered throughout. Species include round-leaved sundew, pitcher plant, leather-leaf, huckleberry, small cranberry, round-leaved shinleaf, bog St. John's wort, and bogbean. Surrounding the eastern edge of the lake are extensive forested wetlands dominated by black ash, green ash, red maple, silver maple, yellow birch, paper birch, and basswood. Near the lake large tamarack and white cedar are co-dominant and the groundlayer is patchy to continuous with a good diversity of both southern and northern species including Canada mayflower, yellow blue-bead-lily, jack-in-the-pulpit, and marsh fern. Pockets of mature mesic hardwoods with sugar maple, beech, red oak, basswood, and white pine are found to the south. The lush growth of emergent vegetation and partial seclusion make this an excellent waterfowl nesting and migration site. Additionally, the undeveloped nature of the site and its location within a rapidly urbanizing area make this site highly valuable waterfowl and wildlife habitat in the southeastern portion of Wisconsin. Huiras Lake is owned by the Ozaukee Washington Land Trust and DNR. It was designated a State Natural Area in 2002.


Driving directions

From the intersection of County Highways Z and I in Waubeka, go north on I 2.4 miles, then west and north on Clover Valley Road 0.3 mile to a pull off where the road turns north. Walk south through the field to Huiras Lake.

Visit the Ozaukee Washington Land Trust [exit DNR] for hunting opportunities on their property. DNR lands are open for hunting.


Huiras Lake is owned by:

  • Ozaukee Washington Land Trust
  • 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.

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.

Hunting and trapping

This SNA has multiple landowners: Opportunities for hunting and trapping depend on the land owner. In general, most DNR-owned land allows hunting and trapping. Partner-owned land may have other rules (for example, university-owned lands do not allow hunting or trapping). 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 "Resource links" heading above. More details regarding allowable uses on the non-DNR land may be found under the "Access" tab above, if available.
