State Engineer John H. Lewis and USGS geographers surveyed this portion of the Willamette Valley in 1912 and 1913, revealing a landscape defined by complex river hydrology and evolving transport. The Willamette River meanders through the center, creating a patchwork of islands like Stallbush Island and Fisher Island, alongside oxbow features such as Horseshoe Lake and Ashahr Lake. These waterways served as vital corridors, with Fisher Ferry and Stallbush Ferry providing essential transit points before modern bridging.
