2021 Map of Irma Flats

About this map

Irma Flats and the surrounding high-desert landscape are defined by the critical management of water in this arid Park County region. The expansive Buffalo Bill Reservoir dominates the northern reaches, fed by the Buffalo Bill Reservoir Springs and the South Fork Shoshone River. This water is harnessed and distributed through an intricate network of irrigation infrastructure, including the Cody Canal and Lakeview Ditch, which support local agriculture and development at the foot of Cedar Mtn. The map reveals a transition from traditional routes like the Stagecoach Trl to modern residential corridors such as S Fork Rd and Diamond Basin Rd. Small drainages including Marquette Cr and Diamond Cr carve through the terrain, illustrating the complex hydrology that governs settlement patterns in the Wyoming basin as of the early 21st century.
