Timelapse video shows construction of fish-friendly culvert in Troutdale

A new timelapse video produced by Multnomah County’s Office of Sustainability shows the four-month construction of a fish-friendly culvert in Troutdale in a little more than two minutes.

In 2017 a contractor working for Multnomah County replaced a narrow box culvert that carried Beaver Creek under Stark Street next to Mount Hood Community College in Troutdale.  The old culvert was a barrier that prevented salmon from reaching spawning areas upstream. Several species of protected salmon thrive in the lower section of the creek.  A larger arch culvert was installed during the summer with a natural creek bottom.  Within two weeks of project completion, native salmon were spotted swimming through the culvert.

The culvert replacement is one of several Multnomah County projects that will open several miles of Beaver Creek habitat for threatened fish species in the next several years. A culvert under Cochran Road upstream from Stark Street will be replaced with a bridge in 2019.
