Antelope Flat and Little Mud Flat characterize this high-desert landscape in Malheur County, where water management defines the human footprint. The map reveals a complex system of catchment basins including the Copeland Reservoirs, Kid Flat Reservoir, and McNulty Reservoir, which capture seasonal runoff from drainages like Butte Creek and Wildcat Creek. This network of small-scale impoundments, often named for local figures or terrain features like Robinson Reservoir and Little Joe Reservoir, illustrates the vital infrastructure required for ranching and resource management in eastern Oregon's arid interior.
