Mullet Creek Wildlife Area

Mullet Creek Wildlife Area is a 2,217-acre property located in east-central Fond du Lac County. The wildlife area is located 15 miles east of Fond du Lac, and 10 miles west of Plymouth on Highway 23. Travel south of Highway 23 on Cty. Trk. G for one mile to the northeast corner of the wildlife area. This is where Mullet Creek flows under Cty. Trk. G.

Mullet Creek Wildlife Area consists of a rich array of wetland, forest, grassland and farmland. Mullet Creek flows through the entire property eventually joining the Sheboygan River. The central portion of this property consists of shallow open water with submergent vegetation and cattail wetland totalling over 700 acres. Sedge, reed canary grass, willow, dogwood, swamp conifers and swamp hardwoods occur in the lowland areas. Oak, aspen and grass fields occur on the upland sites.

The 495-acre Mullet Lake State Natural Area is located about 1/2 mile southwest of Mullet Creek Wildlife Area. The 200-acre hard-water seepage lake is surrounded by a wetland complex of tamarack, shrub carr, sedge meadow, and swamp forest. The lake and swamp complex is the headwaters of the Mullet River in the priority watershed of the Sheboygan River. This undeveloped inland lake with intact wetland vegetation provides important breeding, nesting, and migratory habitat for numerous bird, reptile, and amphibian species. Also, Mullet Creek Wildlife Area is located in the Middle to North Kettle Moraine Priority Conservation Opportunity Area [PDF] - a terrestrial opportunity area of continental significance within the Southeast Glacial Plain Ecological Landscape.


Mullet Creek watershed was formed by glacial activity during the Wisconsin glacial period, some 10,000 years ago. It is an extension of the Kettle Moraine landform. Topography of the property is characterized by a broad, flat basin through which the Mullet Creek flows. Rolling drumlins surround this floodplain. Mullet Creek was periodically stocked with trout until the mid-1950's. A beaver colony constructed a dam on the creek just west of the Sheboygan County line and flooded an extensive area. The flooded area created by the beaver dam was a haven for waterfowl, primarily mallard, wood duck and blue-winged teal. In 1958, the Wisconsin Conservation Commission designated it as a state property. Land acquisition began in 1960 and continues today.

Annually, grasslands are maintained on the wildlife area by prescribed burning in both spring and fall. This is necessary to maintain the vigor of the grasslands but also set back brush/tree encroachment. Recently, the implementation of a sustainable forest habitat management program has been developed for the wildlife area. A more active timber management program will be used to manage the different forest types benefiting the forest dwelling wildlife species on the property.
