1980 Map of Brewster Reservoir

About this map

The North Fork Owyhee River carves a deep, sinuous path across this high-desert landscape near the Oregon and Idaho border, where ranching operations like Brewster Ranch and Circle Bar Ranch found footing in a dry environment. A complex network of water management features, including Brewster Reservoir, Little Groundhog Reservoir, and North Fork Reservoir, illustrates the significant efforts required to sustain livestock and life in this arid region during the late twentieth century.
