Allenton Marsh Wildlife Area


Allenton Marsh Wildlife Area is a 1,160-acre property located in Washington County. Find it 40 minutes north of Milwaukee and west of Highway 41. The property is comprised mostly of wooded bottomland surrounded by grassland and crop fields, two 10-acre impoundments, several dozen smaller ponds and other wetlands, fence lines, feeder streams and small woodlots.



Allenton Marsh was the site of a glacial lake which, through the process of succession, turned into a wooded bottomland, producing the area as it exists today. An abundant water supply from the many springs and creeks made this a good habitat area. With the advance of agriculture into the region, the marsh was subjected to timber cutting and cattle grazing. With the development of new agricultural methods, dairy and beef cattle grazing became important, altering the marsh's vegetation complex. Rising costs in fencing material and labor caused a decline in interest in these lands by farmers and eventually provided an opportunity for public ownership and preservation of the area. In 1953, Walter Brinkman, one of the key landowners on Allenton Creek, offered his property for sale to the state.

Management objective

Pheasants are stocked for hunting once or twice each week during the first month of the pheasant season. Upland fields are managed as nest cover or as cropland to provide wildlife food and cover. These areas, along with numerous man-made potholes, should provide good dove hunting opportunities. Wooded and wetland areas are managed to provide habitat for deer, turkeys, waterfowl and other game and non-game species.

Hunting: Archery and firearm hunting are open on the marsh. The main huntable species are pheasants, deer, turkeys and waterfowl, but raccoons, coyotes, woodcock, cottontails, squirrels and other small game can also be found. "Closed Area" boundaries are posted with yellow signs. Hunting and trapping are prohibited in these areas.
