Environmental Services, Portland Parks & Recreation, and the U.S Army Corps of Engineers worked together on a large-scale habitat enhancement project to benefit wildlife and people. The project restored 75 acres of wetland habitat in 2018.

Learn about the restoration work at the refuge

Project Overview

Between July and November 2018, The Bureau of Environmental Services together with Portland Parks & Recreation and the U.S. Army Corps of Engineers:

  • Replaced a culvert with a larger passage to improve fish passage and the flow of water between the Willamette River and the Oaks Bottom Wildlife Refuge.
  • Excavated new channels and improved wetland habitat so young fish, including species listed as threatened or endangered, can use the calmer waters of the wetland to rest and find food.
  • Removed invasive vegetation, such as purple loosestrife, and plant native seed within the construction footprint.  Native plants were added in February 2019.
  • Enhance opportunities for environmental education and interpretation of the refuge from the Springwater Trail with viewing platform overlooking the refuge.
