Geography
[
edit
]
Sioux County lies on the south line of North Dakota. Its south boundary line abuts the north boundary line of the state of
South Dakota
. Its north boundary line is formed by the east-northeastward-flowing
Cedar Creek
, which discharges into the
Missouri River
at the county's northeast corner, and its east boundary line is formed by the south-southeast-flowing Missouri River, which also forms
Lake Oahe
along the county boundary line. Porcupine Creek flows southeastward into the Missouri River, draining the northeastern part of the county. The county terrain consists of low rolling hills etched with gullies and drainages; the area is mostly devoted to agriculture.
[4]
The terrain slopes to the east and south; its highest point is on the west line, near the southwestern corner of the county, at 2,602 ft (793 m) ASL.

The county has a total area of 1,128 square miles (2,920 km
