About this map

The Owyhee River carves a deep path through Malheur County on this modern survey, defining the core of the Owyhee Wild and Scenic River corridor. The waterway is flanked by dramatic geological formations, including the Owyhee Canyon and the notable Chalk Basin. The landscape is dominated by high plateaus and rims, such as Bogus Rim, with the namesake Lambert Rocks standing as a central landmark above the river's winding course.

Water management is evident through numerous upland catchments, such as Morcom Reservoir Number Two, Anawalt Reservoir, and Red Line Reservoir. These features, along with names like Bogus Ranch Rd and Airstrip Rd, indicate a landscape shaped by remote ranching operations and drainage control. The map also captures the confluence of seasonal flows like Ryegrass Creek and White Rock Creek as they descend toward the main river canyon.
