1969 Map of San Luis Dam

USGS Topo · Published 1980

About this map

The massive water management infrastructure of western Merced County dominates this late 1960s landscape, centered on the San Luis Reservoir State Recreation Area. This era saw the completion of the San Luis Dam and the O'Neill Dam, creating the sprawling O'Neill Forebay and the main reservoir. These features represent a pivotal moment in California's hydraulic history, where the California Aqueduct, San Luis Canal, and Delta-Mendota Canal all converge near a specialized Pumping-Generating Plant.
