Unit Crawford

The Mississippi River system defines navigation here. Major backwater features include Upper Marais, Lafayette Lake, and Spring Lake—all significant water bodies affecting movement and access. Saint Feriole Island, the largest named island, sits in the river channel.

Plainview Ridge and North Clayton Ridge rise visibly above the floodplain and serve as orientation points. Prairie du Chien anchors the south end; Lynxville and Ferryville provide northern reference points. Haney Valley and the slough network (Ferry, Crooked, Capoli) are local hunting landmarks.

Fort Crawford (historical site) marks Prairie du Chien proper.

Terrain spans from river level around 584 feet to modest ridgeline elevations near 1,300 feet, creating natural habitat zones. Low-lying areas support dense wetland vegetation, backwater forests, and marsh—the dominant feature. Uplands transition to mixed deciduous forest and agricultural clearings.

About half the unit is open country or grassland; the remainder splits between forested ridges and bottomland timber. The combination of water-dependent habitat and upland woods creates classic Driftless Area terrain: productive but compartmentalized by water barriers and private ownership patterns.

Road density of 2.63 miles per square mile means the unit is well-connected and easily navigated. State and county roads provide systematic access; most hunters access via vehicle rather than foot travel. However, private ownership limits where you can legally hunt.

Public land hotspots (boat launches, state wildlife areas, park access) see concentrated pressure, particularly during firearm seasons. Early-season bowhunters can often find solitude by accessing less-visible private property via permission. The straightforward terrain and good roads mean new hunters can cover country efficiently, but finding huntable ground depends on landowner relationships.

Crawford occupies the Mississippi River floodplain and adjacent upland areas in southwestern Wisconsin, anchored by the town of Prairie du Chien. The unit sprawls across roughly 600 square miles of mixed ownership, though nearly 92 percent is privately held. The Mississippi River forms the western boundary and dominates the geography with its expansive backwater system.

Flat to gently rolling terrain characterizes most of the unit, broken by occasional ridge systems that rise modestly above the floodplain. This is agricultural and river-bottom country first, with hunting access secondary to land use patterns.

Water defines Crawford's character. The Mississippi River dominates, with extensive backwater lakes, oxbows, and slough systems throughout. Upper Marais, Lafayette Lake, Spring Lake, and McGregor Lake are major impoundments.

Numerous named sloughs—Ferry, Crooked, Capoli, Henderson, Stevens, and others—thread through bottomland and provide seasonal water corridors. Sugar Creek, Bear Creek, and Copper Creek are the main upland drainages, but flow is modest. Winneshiek Bottoms represents one of the largest marsh complexes.

Water is abundant but concentrated in specific zones; upland hunting requires understanding seasonal waterhole locations and spring-fed sources.

Crawford supports both whitetail and mule deer across its mosaic of habitat. Whitetails dominate the agricultural transition zones—field edges, creek bottoms, and wooded ridges. Mule deer inhabit the more open, brushy country and ridge systems.

Early season pressure centers on accessible ridgelines and near public water access. As seasons progress, deer move between upland timber and agricultural areas seasonally. The flat terrain makes glassing productive for mule deer on open ridges.

Bowhunting advantages over-the-top terrain near private cover; firearm hunters should focus on drainage systems and ridge saddles. Water crossings and bottleneck terrain near sloughs concentrate movement during rut periods.
