1975 Map of Folsom

About this map

Folsom Lake dominates the upper eastern quadrant of this 1975 orthophotoquad, revealing the shoreline and hydraulic infrastructure during the mid-1970s. This specialized map, produced in cooperation with the Soil Conservation Service, uses aerial photography to provide a literal visual record of land use and development patterns. The growing residential grid of Orangevale is clearly visible to the west, while the historical core and expanding suburban outskirts of Folsom sit between the two major water bodies. Below the dam, Lake Natoma carves a narrow path through the center of the sheet, framed by the distinctive patterns of local terrain and engineering. The imagery highlights the transition from natural riverbanks to managed reservoirs, capturing the footprint of industrial and residential growth in Sacramento County during this era.
