The Clackamas River and Sandy River define the hydraulic and economic landscape of this Clackamas County region in the early 1960s. The map illustrates a transition from the developing outskirts of Gresham to the industrial and agricultural corridors of the south. Significant infrastructure is concentrated near the river bends, notably the Cazadero Powerhouse and Faraday Powerhouse near Estacada, which utilized the river's flow for power generation.
