Unit 22A

Major water features dominate: Waubay Lake and the Waubay Lakes complex form the geographic heart, with Long Lake, Hillebrands Lake, and numerous sloughs scattered throughout. Wingate Arm extends into the unit, creating distinctive water boundaries. Smaller lakes—Horseshoe, Lonesome, Lynn, and Little Rush—dot the grassland and serve as watering holes and navigation references.

Chekepa Creek and Antelope Creek provide drainage corridors with riparian cover. These water features are easy to locate and glass from, making navigation straightforward. The populated places—Webster, Waubay, Pierpont—are logical reference points for orienting to the country.

The entire unit sits in the lower elevation band with no significant vertical relief. Prairie grassland dominates the open country—native and introduced grasses that transition seasonally from green growth to dormant brown. Scattered patches of willow, cottonwood, and aspen appear along creek bottoms and slough margins, but dense forest is absent.

The habitat is semi-arid prairie interspersed with wetlands; water features create distinct microhabitats where trees and shrubs cluster. Early season finds green grass and active water; late season means dormant grassland with water concentrated in larger lakes and reservoirs. This is wide-open country where you see long distances across flat terrain.

The well-developed road network (2.19 miles of road per square mile) makes Unit 22A highly accessible. Major highways and secondary roads crisscross the grassland, enabling quick movement and multiple entry points. However, 96% private ownership severely restricts actual hunting opportunity.

Public land is minimal, so success depends almost entirely on locating private landowner access. The developed road network means most hunters can hunt this unit, creating significant competition for limited public and permissioned private land. Pressure concentrates on accessible water bodies and known public areas near towns.

The vast flat terrain means movement is easy but also means hunting pressure can spread quickly once hunters identify hot spots.

Unit 22A occupies the northeastern corner of South Dakota, a vast tract of prairie spanning roughly 1,091 square miles. The unit is defined by the Missouri River drainage system and encompasses the Waubay Lakes region and surrounding grasslands. Towns like Webster, Waubay, and Pierpont provide services and staging points for hunters.

The landscape is fundamentally glaciated prairie—flat to gently rolling terrain shaped by the last ice age, with no significant mountains or steep topography. This is the northern Great Plains in character, where elevation barely exceeds 2,000 feet and water features dominate the visual landscape.

Water is the defining feature of Unit 22A. Multiple lakes and reservoirs, including Pierpont Lake and Amsden Lake, provide permanent water sources. The Waubay Lakes system anchors the unit with connected water bodies creating navigation pathways. Numerous sloughs—Stangland, Holmquist, Headman—hold water seasonally and provide wildlife concentration points.

Chekepa Creek and Antelope Creek drain the grasslands with riparian vegetation offering cover and food. Water is abundant enough that it's rarely a limiting factor for hunting strategy. Late season may concentrate wildlife around the deepest lakes and largest sloughs as smaller water sources freeze or dry.

Hunting pressure often concentrates around accessible water, making hidden sloughs valuable for pattern interruption.

Unit 22A supports white-tailed deer, mule deer, and crossbred populations—the primary hunting focus. White-tailed deer dominate the brushy creek bottoms and slough margins, particularly cottonwood and willow thickets. Mule deer use the open grassland and transition zones, often working grain fields and prairie margins.

Early season finds deer scattered across the grassland; rut timing drives movement into heavier cover near water. Late season concentrates deer around remaining food sources and water. Hunting success requires either private land access or knowledge of specific public areas.

Glassing from roads and water edges works in this open country. Creek bottoms and slough margins—especially where vegetation thickens—hold concentrations of deer. The flat terrain favors stalking or sitting water sources over driving draws.
