2021 Map of Coyer Reservoir

USGS Topo · Published 2021

About this map

Coyer Reservoir and the surrounding high plains of Johnson County define this specialized landscape of water management and remote grazing land. In a region where seasonal moisture is critical, the map documents a series of man-made impoundments including Iberlin Reservoir and Flaxa Number 1 Reservoir, which capture runoff from the complex network of ephemeral drainages. The local geography is etched by numerous named draws such as Whisky Draw, Goble Draw, and Joe Draw, which feed into the N Fork Fourmile Creek and South Fork Fourmile Creek. The Iberlin Strip and the winding Iberlin 4-Mile Road indicate the long-standing ranching presence of the Iberlin family in this part of Wyoming. This map serves as a detailed record of land use and water rights in a part of the West where topography and access are dictated by the flow of the Fourmile Creek watershed.
