Unit Columbia

Lake Wisconsin and its connected reservoirs form the dominant waterscape and serve as primary orientation points. The Wisconsin River itself, including its wider sections and oxbow lakes like Lake George, provides navigation corridors and deer travel routes. Cascade Mountain, Whites Bluff, and Pine Bluff offer slight elevation relief useful for glassing open country.

Merrimac Ferry crosses the Wisconsin River and marks a major access point. The Portage Canal and various smaller lakes—Swan Lake, Goose Lake, Weeting Lake—break up the agricultural landscape and indicate good water availability for hunting camps.

This unit stays low and productive throughout. Scattered deciduous timber—oak, maple, ash—occupies maybe 16 percent of the landscape, primarily along drainages and in protected valleys. The remaining 80 percent is open agricultural land: cropfields, pasture, and prairie grassland.

Wetlands and water features comprise nearly 3 percent of the area. Habitat transitions are gradual rather than dramatic; you move from field to timber edge to creek bottom rather than climbing through distinct vegetation zones. The open country provides good visibility for hunting, while timber patches concentrate deer in predictable corridors.

This is connected country with 3.24 miles of road per square mile—a well-developed infrastructure that makes access straightforward but also concentrates hunting pressure. State Highway 39 crosses the unit; County Roads branch extensively into agricultural areas. However, 94.5 percent private land means access depends entirely on permission.

Most hunters work private ground near towns like Portage, Dells, and Lodi. Public water access along the Wisconsin River and at designated boat launches provides some opportunities. The low complexity and easy roads mean this unit fills quickly during rifle season; successful hunting often requires established private land relationships.

Columbia unit occupies the southcentral Wisconsin driftless region, anchored by the Wisconsin River which runs through its middle. The landscape stretches across rolling agricultural country interspersed with glacial lakes and managed wetlands. Wisconsin Dells and Portage sit on the unit's periphery, providing reference points and services.

The terrain is fundamentally a transition zone between hardwood forest and prairie, shaped by water features rather than dramatic topography. Elevation change is modest—roughly 750 feet to 1,500 feet—creating gentle slopes that rarely exceed a few hundred vertical feet.

Water is genuinely abundant here. The Wisconsin River runs north-south through the unit, flanked by oxbow lakes and backwater areas that hold deer and provide reliable hunting water. French Creek, Hinkson Creek, and Spring Creek offer additional perennial drainages with associated cottonwood and willow bottoms.

Numerous named lakes and reservoirs—37 Reservoir, Columbus Mill Pond, Lazy Lake 61, and others—dot the landscape. Smaller ponds and wetlands fill the gaps. Seasonal water varies; major lakes and the river itself stay reliable year-round, but smaller creek sections may run low in late summer.

White-tailed deer dominate here; this is classic agricultural country with mule deer rare or absent. Deer use field edges, creek bottoms, and timber patches in predictable patterns. Early season (archery) hunting focuses on field edges during morning and evening feeding periods—stand placement where timber meets cropland is effective.

Rut hunting uses scrapes and rubs in scattered woodlots and ravines. Late season deer move into river bottoms and dense cover, particularly the Wisconsin River corridor and its associated swamps like Schoeneberg Marsh. Scouting during off-season identifies field patterns and preferred bedding cover.

Success hinges on finding accessible private ground; public hunting opportunities are limited but possible along river access points and designated public hunting areas.
