About this map

The North Fork Owyhee River cuts a deep course through this high desert terrain, designated here as the Owyhee Wild and Scenic River. This modern survey reveals a landscape defined by water management and ranching infrastructure, where numerous small reservoirs like Brewster Reservoir and Little Groundhog Reservoir collect seasonal runoff. The topography is marked by significant elevation changes, from the steep walls of Little Box Canyon to the fractured slopes of the Pole Creek Breaks.

Ranch roads such as Parker Reservoir Rd and Fenwick Ranch Rd provide the primary access to remote points like Soldier Meadows and Dutcher Spring. The map documents a complex system of drainage, including Ra-ba-Tehaga Creek and Dutcher Creek, which feed into the primary river corridor. These features reflect the ongoing necessity of water catchment in the arid borderlands of Malheur County, sustaining the pastoral use of the land.
