Jefferson sits at the heart of this survey, positioned where the fertile plains of Union Co meet the winding corridors of the Missouri River and the Big Sioux River. The landscape is defined by its riparian geometry, with the oxbow of McCook Lake serving as a prominent landmark south of the main settlement. This area represents a critical tri-state junction where South Dakota, Nebraska, and Iowa converge, a fact reflected in the diverse road network including Co Rd 18 and Main St that connect these agricultural and residential hubs.
