1972 Map of Polk City
USGS Topo · Published 1975About this map
The Des Moines River valley undergoes a significant transformation on this early 1970s survey, defined by the engineering of the Barrier Dam and the rising waters of Saylorville Lake. This era marks the transition of the central Iowa landscape from a riverine agricultural corridor to one dominated by large-scale water management and recreation, as seen with the formation of Big Creek Lake. Despite these changes, the rural township structure of Garden, Palestine, and Lincoln remains visible through a grid of numbered roads like NW 166th Avenue.
