1954 Map of Navajo Dam

About this map

The Navajo Dam infrastructure and the rising waters of the Navajo Reservoir define this mid-century landscape on the border of San Juan and Rio Arriba Counties. Revised in the early 1970s, the map documents the dramatic transformation of the San Juan River valley into a massive water storage system. Significant portions of the rugged terrain, including Navajo Lake State Park, are highlighted for controlled inundation, illustrating the engineering scale required to support the Navajo Indian Irrigation project. High tablelands like Frances Mesa and Manzanares Mesa overlook the deepening canyons. Beyond the water works, the map reveals a burgeoning energy landscape, marked by a dense network of gas wells and pipelines such as the Pine River Road pipeline that crisscross the mesas, connecting remote extraction sites through Gobernador Canyon and Spirit Canyon.
