2022 Map of Julesburg Reservoir

About this map

Julesburg Reservoir dominates the landscape of eastern Logan County and western Sedgwick County, serving as a focal point for the region's complex water management system. The map reveals an intricate network of late 20th-century irrigation infrastructure, including the Harmony Ditch Number 1, Highline Canal, and Sterling Outlet Canal. These engineered waterways, alongside the South Platte River, underpin the agricultural character of the high plains near Red Lion and Marcott. North of the reservoir, the terrain transitions into the dry drainages of Cottonwood Creek and its western fork, where landmarks like Flat Top and Bolick Spring dot the landscape. The layout of county roads, such as Red Lion Road and Co RD 138, reflects a rural settlement pattern deeply tied to both the river valley and the storage capacity of the Dickinson Irrigation Reservoir.
