Introduction: Sedgwick County is in the extreme northeast corner of Colorado. It has the lowest average elevation of any county in Colorado. It is sparsely populated and arid. The main geographic feature of Sedgwick County is the South Platte River, which enters from Logan County to the west and exits north into Nebraska just east of Julesburg. The river bottom hosts a strip of riparian timber, primarily cottonwoods. I-76 runs on the south side of the river and State Highway 138 parallels the river on the north. The towns of Sedgwick, Ovid, and Julesburg are all on Highway 138, north of the river. River crossings connect these three towns to Interstate exchanges. Much of the land north of the river is hills and prairies. South of the Interstate is a narrow band of hills, and south of that is mostly flat cropland. Much of the river valley is irrigated cropland.
