2012 Map of Arrowhead Reservoir

About this map

Arrowhead Reservoir and the surrounding high plains of Crook County are defined by a network of drainage draws and small water catchments essential for ranching. This 2012 survey illustrates the importance of managed water in a semi-arid landscape, featuring Hagerman Reservoir and Upton Reservoir alongside numerous named topographical depressions such as Deep Draw and Fredrickson Draw. The drainage system is complex, with Willow Cr, Arch Cr, and Mason Cr cutting through the terrain towards the larger Sage Cr basin. Access across this landscape is maintained via a grid of rural routes including Arch Creek Rd and Upper Inyan Kara Rd, which connect remote landmarks like Hopper Flat and the deep incisions of Baker Canyon to the wider region.
