Unit 01A

Sioux Falls itself serves as a major geographic anchor at the unit's eastern edge. The Dells of the Sioux River and associated cliffs provide topographic relief and navigation references in an otherwise flat landscape. Clear Lake, Wall Lake, and the various sloughs throughout the unit mark water concentrations where deer predictably gather, especially during dry periods.

Silver Creek, Split Rock Creek, and Skunk Creek form the major drainage systems; these creek bottoms are critical navigation corridors and prime deer habitat. Rocky Ridge and the Cactus Hills offer minor elevation changes useful for orientation in otherwise undulating country.

The entire unit sits in the lower prairie zone with no significant elevation changes—the landscape is predominantly open grassland and cropland interspersed with scattered timber along drainages. Vegetation is minimal timber and maximum open country, with most trees confined to creek bottoms, around lakes, and in scattered shelterbelts on farms. Habitat transitions subtly from one drainage to the next rather than in distinct elevation bands.

Deer use the sparse woody cover near water, making creek valleys and willow-lined drainages the primary hunting focus. The openness creates visibility advantages but limited escape cover.

The unit features one of the highest road densities in South Dakota—nearly 4.6 miles of road per square mile—making access extremely convenient but concentrated pressure predictable. Most hunters use the extensive road network for access, glassing from vehicles or making short walks from roadside pull-offs. The challenge is that this same network allows pressure hunters to cover territory quickly.

Finding unhunted country means focusing on less-obvious creek bottoms, private-public boundary areas, and sloughs away from main drains. Sioux Falls provides immediate staging; smaller towns like Colton, Huntimer, and Hartford offer local access points.

Unit 01A encompasses a sprawling section of eastern South Dakota, covering over 800 square miles of prairie and farmland. The unit sits in relatively flat terrain at modest elevations between roughly 1,250 and 1,900 feet. Sioux Falls anchors the eastern side, while the landscape extends west into classic northern Great Plains country.

The Big Sioux River and its tributaries form natural anchors; numerous sloughs and lakes dot the terrain. This is working agricultural country with scattered towns and well-established road infrastructure throughout.

Water features are moderately distributed across the unit, making them critical for hunting strategy. Sioux Falls Diversion Channel, multiple natural lakes (Clear, Wall, Grass, Diamond, Beaver, Buffalo lakes and various sloughs), and interconnected stream systems provide reliable water sources. The Sioux River and its tributaries—Silver Creek, Split Rock Creek, Skunk Creek, and Springwater Creek—form the main drainage network.

These creeks retain water year-round and develop thick riparian cover, making them primary travel corridors and bedding habitat for deer. Lakes and sloughs attract deer in dry periods, particularly late season.

Unit 01A supports mule deer and whitetail deer in a landscape defined by water scarcity relative to sprawl—deer concentrate heavily near lakes, sloughs, and creek systems. Hunt the creek bottoms where riparian cover exists and deer move between water and feeding areas. Early season deer use open grassland; focus on creek-to-field transitions at dawn and dusk.

During rut, bucks move between small woodland patches along drainages—glass from roads, then make strategic walks into willow thickets. Late season, all deer funnel toward reliable water, making lakes and permanent sloughs critical. Success requires scouting to locate active sign and using the road network strategically rather than exploring deep country.
