1967 Map of Prado Dam

USGS Topo · Published 1968

About this map

The Prado Flood Control Basin dominates the lower landscape of this mid-1960s survey, marking a critical point of water management where Chino Creek and Cucamonga Creek meet the Santa Ana River. At the heart of this system stands the massive Prado Dam, a centerpiece of regional infrastructure. The map captures a transition from agricultural use to institutional and residential development, evidenced by the large footprints of the California Institution for Men and the California Institution for Women (Frontera PO).
