2011 Map of Rockhouse Reservoir

About this map

Rockhouse Reservoir and Blevins Reservoir anchor this arid high-desert landscape in southeastern Oregon. The terrain is defined by a dendritic network of seasonal drainages, where Dry Creek and Corbin Creek carve through the basin toward White Mule Flat. Human presence is sparse, marked primarily by isolated water management features and a single named corridor, Indian Fort Creek Rd, which tracks alongside Indian Fort Creek in the northern reach. This survey illustrates the essential role of artificial reservoirs in sustaining livestock or wildlife in a region where natural water flow is ephemeral. The infrastructure recorded here reveals how grazing and water rights shaped the land use patterns of Malheur County in the early twenty-first century.
