Flood control

Historically, the confluence of the Willamette and Columbia rivers has been the site of several flooding events. Multiple entities, including Levee Ready Columbia and several drainage districts, have worked to keep infrastructure strong and reduce flood risk. There are 45 miles of levees near the convergence of the two rivers. Tens of thousands of jobs, homes, farms, parks and natural areas are protected by these levees.
