1956 Map of Lake Eleanor

USGS Topo · Published 1960

About this map

The high Sierra water infrastructure of the late 1950s dominates this landscape, where the Tuolumne River and its forks are harnessed for utility and power. The Hetch Hetchy Reservoir and Lake Eleanor Reservoir are central features, connected by the subsurface Hetch Hetchy Aqueduct (Tunnel) and supported by the Early Intake Powerhouse. This era represents a peak in the management of the watershed, with the newly mapped Cherry Lake expanding the region's reservoir capacity.
