1967 Map of Owyhee Dam

USGS Topo · Published 1971

About this map

Owyhee Dam anchors this landscape, controlling the waters of the Owyhee River and forming the northern reaches of Lake Owyhee. The complex irrigation infrastructure required to manage this arid terrain is clearly visible through a series of engineering features, including the Owyhee Ditch, several elevated aqueducts, and underground passages like Tunnel No 1 and Tunnel No 5. These structures emphasize the mid-century transition of Malheur County into a managed agricultural corridor.
