About the Flood Maps

The Report of the Flood Commission of Pittsburgh, PA contains the results of the surveys, investigations and studies made by the commission for the purpose of determining the causes of, damage by, and methods of relief from floods in the Allegheny, Monogahela and Ohio rivers at Pittsburgh. The study also commented on the benefits to navigation, sanitation, water supply and water power to be obtained by river regulation. The 14 maps were included in the publication by the Pittsburgh, Murdoch, Kerr & Company in 1912. The survey took place between July-October 1909.

In addition to flood level data, these maps depict river depths, land contour, streets, building footprints, railroads, bridges, and various landmarks.
