About this map

The Owyhee River carves a deep, winding path through this Malheur County landscape, defining the steep topography of Owyhee Canyon. The terrain is characterized by dramatic rimrock and basin formations, including the prominent Lambert Rocks, Chalk Basin, and the high edge of Bogus Rim. This area serves as a critical water management zone for high-desert ranching, evidenced by a network of specialized catchment points such as Morcom Reservoir Number Two, White Wash Reservoir, and Red Line Reservoir.

Remote access is maintained through a few named routes like Bogus Ranch Rd and Miller Ln, which connect isolated water sources like Sand Spring to larger drainage systems. The map detail highlights the complex hydrology of the region, where ephemeral streams such as Ryegrass Cr and Bogus Creek feed into the primary river corridor, illustrating the intersection of natural geology and late 20th-century water infrastructure.
