About this map

Silvies River meanders through the southern half of this Harney County landscape, feeding into a complex network of waterways including Fivemile Slough and Foley Slough. This 2014 survey reveals a transition from the riparian lowlands of the river basin to the dramatic elevations of the north, where Mahogany Ridge dominates the terrain. High-country drainage is defined by deep cuts such as Devine Canyon and Black Canyon, which channel seasonal flow toward the valley floor.

Water management is evident through features like Arntz Reservoir and Paiute Reservoir, essential for the region's ranching and agricultural interests. Local access is facilitated by a grid of rural routes like Curry Garden Rd and Lone Pine Rd, while Us-395 skirts the eastern canyons. Named landmarks such as Arrowhead Butte and various upland water sources like Coal Pit Spring provide critical orientation points in this expansive high-desert environment.
