This particular unit hosts more public hunting and walk-in land than average for the east river area, particularly in the north and east. Making up the eastern half of Sully County, this unit is at the western edge of the countries that observe Central Time. Still, the unit is primarily devoted to agriculture so planning ahead and having prior arrangements to access private land may be necessary to ensure a successful hunt.

Even with a larger portion of walk in and public land in this particular unit, having landowner permission will be beneficial.

Making up the eastern portion of Sully County, the terrain is composed of semi-arid rolling hills, partially devoted to agriculture. It slopes to the southeast with a high point of 1,949 ft along its northern boundary. There are a number of lakes and refuge areas in this unit, including Stone and Cottonwood Lakes to the north, and Medicine Knoll Creek Game Production Area in the south. It is a mix of CRP, lake frontage, open grasslands, and agriculture.

This unit is bordered on the west by highway 83, allowing quick access north to south through the entire unit. Along the southern border of Sully County, is County Road 206A, that runs west and east. This road will certainly provide access to the Medicine Knoll Creek Game Production Area in the southeast portion of the unit, as well as some more pockets of state land in the south. To the east there is County Road 649, running the entirety of this unit from north to south, giving direct access to walk-in areas as well as multiple state trust lands to the far north, around Stone Lake. Cottonwood Lake area is another walk-in designated use here, accessible by 311th Ave, which runs again, the entire length of the unit from north to south. The county roads near the north boundary are not as developed, but using a number of paved and marked roads, you should be able to access all the public land areas. Follow all local rules regarding public use.

Vegetation is typical to a grassland environment, a mix of short and tall prairie grass, with most of the land devoted to agriculture. Government partnered CRP is growing throughout the unit, with a healthy mix of food plot seed and grassland restorations being implemented across the state on private land. Towards the boundaries of the unit are multiple creek bottoms, lakes, and woody areas where you will find cottonwood and elm forests, making a rich habitat for whitetail deer, fox, and beavers as well as migratory birds.
