Estacada and the Clackamas River corridor serve as the industrial focal point of this 1916 survey, showcasing early twentieth-century hydropower and municipal infrastructure. The map meticulously records the River Mill Dam and the Upper Dam near Cazadero, alongside the critical Intake Portland Waterworks on the Bull Run River. This era marks a significant transition as the P. R. L. & P. Co. railroad line connects timber and power interests between the growing settlements of Boring, Barton, and Eagle Creek.
