About this map

Round Top Butte rises as a central landmark in this high-desert landscape, where the border between Lake Co and Harney Co divides the high plateaus of south-central Oregon. The map reveals a complex water management system essential for local ranching and land use, defined by a network of isolated catchments including North Sheep Mountain Reservoir, West Sheep Mountain Reservoir, and Manoeuvre Road Reservoir.

Surface drainage is ephemeral and often subterranean, evidenced by the Sinks of Lost Creek where water vanishes into the volcanic terrain west of Lost Cr Reservoir. Seasonal water sources like Anderl Lake and Pasture Lake are supplemented by scattered perennial points such as Skookum Spring and Bradley Spring. The presence of Big Stick Rd provides the primary transit route through this open country, connecting the foothills of Sheep Mtn to the surrounding basins.
