In 2013, we began a project to learn about the ways local industry affected Marys River and its tributaries over time. We were particularly curious about the two dams that spanned the mainstem Marys just above Avery Park and at the confluence with the Willamette.  We will be telling the story of past uses of the Marys through maps and photos through a month-long exhibit at the Corvallis-Benton Public Library in April 2015.  Watch this page for updates!
