2019 Map of Iliff

About this map

Iliff and the surrounding Logan County agricultural landscape are defined by a complex network of irrigation infrastructure essential to the High Plains. This 2019 survey captures the managed flow of water through the South Platte River valley, where the Iliff-Platte Valley Ditch, Iliff Ditch, and Lone Tree Ditch parallel the river's course to support local farming. To the north, larger-scale water management is visible via the North Sterling Outlet Canal and secondary distribution lines like the Naugle Number 27 Lateral and Gillette Number 26 Lateral. The settlement of Iliff is organized along Railroad Ave and Logan Ave, while nearby Selma and Griff sit positioned along the rail corridor and South Platte River. The map also documents smaller water bodies and catchment areas including Breidenbach Reservoir, McKenzie Pond, and Larson Pond, which are tucked into the terrain alongside Lewis Cr and Sevenmile Cr.
