Topographical map of Seattle, Washington, 1909, showing the projected rerouting of the Duwamish River, route for the Lake Washington Ship Canal, and other shoreline proposals. This is more or less what was done (although, for example, more oxbows of the Duwamish were filled in, and not as much change was made to Lake Washington.) Original caption: "Seattle Harbor after the completion of The Lake Washington Ship Canal and Duwamish River Improvement".
