Oakridge and Willamette City anchor the northwestern corner of this survey, marking a period of significant infrastructure development along the Middle Fork Willamette River. The most striking industrial change is the Hills Creek Dam, then under construction on Hills Creek. This massive engineering project was reshaping the local landscape and hydrology, eventually creating a reservoir where the river once flowed past Sand Prairie.
