Unit St Croix

Key landmarks include the St. Croix River itself, which defines the unit's eastern character and serves as a navigation reference. North Bass Lake, Three Lakes, and Twin Lakes provide water-based orientation points; several other named lakes and ponds dot the landscape.

Tenmile Creek and Willow River are significant drainages running through the unit. The rolling terrain includes gentle summits like Coons Hill and Big Mound, which offer minimal elevation gain but serve as glassing points over the prairie. Communities including Hudson and North Hudson anchor the western and southern margins, providing logical staging areas for hunters.

Anderson Springs, Levesque Spring, and Hennessey Spring indicate reliable water sources.

This entire unit sits at lower elevation, spanning roughly 500 vertical feet across rolling topography. The landscape is dominated by open prairie and grassland interspersed with oak savannas and mixed hardwood stands—about 71 percent is prairie and grassland with limited forest, while roughly 23 percent combines forest with open ground. Agricultural lands, pasturelands, and remnant oak savanna form the primary habitat mosaic.

Water features are abundant, including numerous lakes, ponds, and springs scattered throughout. The habitat supports white-tailed deer across a mix of open feeding areas and brushy cover, with the river corridor providing riparian timber corridors.

Road density is very high at 6.06 miles per square mile, meaning nearly every section is accessible by vehicle. Major highways and state routes traverse the unit, with over 275 miles of major roads creating well-defined corridors. This connectivity supports easy access but also concentrates hunting pressure along roadsides and accessible private lands.

The unit is only 5.7 percent public land, making private land access critical. The proximity to Hudson and other communities means weekend pressure is typical. Success depends on identifying private land access opportunities and hunting away from main roads into the agricultural matrix where deer concentrate.

The St. Croix unit occupies a compact 179-square-mile area in northwestern Wisconsin, anchored by the St. Croix River valley and adjacent communities including Hudson, Houlton, and North Hudson.

The landscape transitions between Minnesota and Wisconsin, with the river serving as a natural eastern boundary. Elevation varies gently from around 660 feet in low areas to just over 1,100 feet on ridges—modest changes that define the unit's character. The terrain is fundamentally agricultural and pastoral, representing the transition zone between upper Midwest prairie and the conifer-hardwood forests that dominate farther north.

Water is one of the unit's defining features. The St. Croix River corridor dominates the eastern portion, providing year-round flow and riparian habitat.

Numerous lakes and ponds—North Bass Lake, Three Lakes, Twin Lakes, Perch Lake, Shank Lake, and others—scatter across the landscape, with most remaining fairly reliable throughout the year. Tenmile Creek and Willow River serve as major drainages, while smaller streams and springs including Anderson Springs and Levesque Spring provide additional water sources. The landscape's rolling glacial character ensures adequate moisture; water scarcity is not a hunting concern.

Seasonal fluctuations exist but don't dramatically impact accessibility.

White-tailed deer are the primary quarry, with some mule deer presence. The open prairie and oak savanna habitat supports solid deer populations across the unit, though public land limitations mean private access is essential. Early season hunters should focus on field edges and brushy transitions where deer feed on agricultural crops and native vegetation.

The abundant lakes and water features mean deer don't concentrate heavily at isolated water sources. The St. Croix River corridor and its riparian timber provide late-season holding habitat when pressure increases.

Hunting the margins between open ground and timber edges—particularly near the lakes and creek systems—is most productive. Road access is easy, but the best country requires scouting private lands and establishing relationships with landowners.
