1999 Map of Mae

About this map

Hiawatha Valley characterizes the northern reaches of this Grant County landscape, where the small settlement of Mae sits near a local Cemetery and benchmark. The terrain is dominated by the massive hydrologic footprint of The Potholes Reservoir, showing an elevation of 1039 feet recorded in June 1956. This reservoir system, essential to regional irrigation and habitat, anchors the South Columbia Basin State Wildlife Recreation Area. Large expanses of Sand Dunes shift across the basin, punctuated by occasional industrial sites like a Gravel Pit and the small locality of Camas. The map illustrates a high-desert environment transformed by mid-century water management, where the intricate shoreline of the reservoir meets the natural wind-blown topography of the Columbia Basin.
