Unit 108

The unit's numerous lakes and flowages serve as primary navigation anchors. Hay Creek Flowage, Clam Lake, Danbury Flowage, and Memory Lake are substantial water bodies that break up the landscape and help orient hunters. Pike Lake, Reed Lake, and Tobe Lake offer additional reference points.

Rocky Ridge Creek, Barrett Creek, and Bear Brook cut through the terrain as natural travel corridors that concentrate deer movement. Pease Hill provides modest elevation to glass from, though open vantage points are limited by the dense forest. The named marshes—especially Kilkare Marsh and Currey Flowage—mark transition zones where deer often concentrate during hunting season.

All terrain sits well below 5,000 feet, creating uniform vegetation zones typical of northern Wisconsin. Dense coniferous and mixed forest dominates roughly half the unit, with scattered hardwoods and aspen throughout. Open grasslands, brush, and agricultural areas make up the other forest-free half, creating productive edge habitat.

Swamps and marshes—including extensive flowages like Currey Flowage, Kilkare Marsh, and Upper Hay Creek Flowage—break up the timber and provide natural travel corridors for deer. The gentle terrain and abundant water mean most of the unit supports consistent deer habitat; elevation changes are subtle but enough to create ridgeline cover and drainage bottlenecks hunters can key on.

The road density of 2.91 miles per square mile creates a well-connected network. Highway corridors like those near Grantsburg, Danbury, and Siren provide easy entry, and county and township roads penetrate most of the unit. This accessibility brings consistent hunter pressure, particularly near road access points and obvious water features.

However, the unit's 762 square miles and dense timber mean walking away from roads quickly puts hunters into quieter country. Most pressure concentrates near parking areas and along obvious corridors; the surrounding forest sees lighter use. Planning to access less-obvious entry points and being willing to walk reduces pressure encounters significantly.

Unit 108 covers 762 square miles of northwestern Wisconsin between the towns of Grantsburg, Danbury, and Siren. This is classic North Woods country—a patchwork of public and private land dominated by forest and water features. The unit sits at modest elevations ranging from roughly 750 feet in the lowlands to just over 1,300 feet on higher ridges, with most terrain falling in the 900-1,000 foot range.

It's big enough to absorb pressure but small enough that hunters can cover meaningful ground in a day. The connected road network and numerous small towns on the periphery make staging and resupply straightforward.

Water is abundant and reliable throughout Unit 108. Dozens of lakes, reservoirs, and flowages mean standing water is rarely more than a mile away. The Clam River system and its associated flowages provide perennial water down the unit's centerline. Smaller creeks like Barrett Creek, Rocky Ridge Creek, Kettle Brook, and Spring Brook all run year-round in most seasons.

Boyle Brook Spring offers reliable groundwater. This abundance of water means deer don't concentrate at traditional watering points—they're distributed throughout the unit wherever cover meets water. Hunters should plan water sources for themselves but understand deer won't follow predictable drinking patterns.

Unit 108 supports both white-tailed and mule deer, though white-tails dominate. The mix of dense forest, edges, and abundant water creates consistent deer habitat across elevations. Early season hunting targets deer using field edges and open ridges during summer movement patterns; scouting agricultural areas and timber openings pays off.

As temperatures cool in mid-season, deer move deeper into forest cover but remain water-dependent; focus on creek corridors and marsh edges where trails concentrate. Late season pushes deer toward remaining open areas and browse; ridgelines and areas with younger regenerating timber become productive. The flat to rolling terrain means stalking is viable from open spots, and the extensive flowages create natural funnels where deer cross between timber blocks.

Pressure management through positioning away from road access is key to consistent success.
