Lake Decatur and the eastern edge of Decatur anchor this central Illinois landscape, where the prairie transitions into the managed hydrology of the Sangamon river system. The terrain is a network of rural hamlets and agricultural infrastructure, connecting Oakley in the north to the junction at Hervey City and Prairie Hall in the south. Aviation is a prominent feature of the local economy, represented by the expansive Decatur Airport and the smaller Corman Acres Airport to the southeast.
