1967 Map of Owyhee

About this map

The confluence of the Snake River, Owyhee River, and Boise River defines this agricultural landscape along the Oregon-Idaho border during the late 1960s. The settlement of Nyssa occupies the northern edge, while smaller communities like Riverview, Overstreet, and Owyhee are linked by a grid of named avenues and the Union Pacific railroad. The map reveals an extensive irrigation network essential for the region's productivity, including an Aqueduct, multiple siphons, and flumes that channel water across the Lincoln Bench and through Cow Hollow.
