2011 Map of Big Mud Flat

About this map

Mud Flat Ranch and a series of private water management features define this high desert landscape in southeastern Oregon. This portion of Malheur County is characterized by significant topographical shifts, from the broad expanse of Big Mud Flat to the dramatic elevation changes at Owyhee Breaks and Wrangle Basin. The distribution of water is a central theme of the map, evidenced by numerous named reservoirs and dams such as the David Kent Dam and Black Canyon Creek Dam. Many of these features, including Knottingham Reservoir and Harry Page Reservoir, appear to be named for local individuals or ranching families, providing valuable clues for genealogical research. Connectivity in this remote region is maintained by unpaved routes like Antelope Flat Rd and Turner Rd, which navigate the drainages of Black Canyon Creek.
