Bringing salmon back to Crystal Springs Creek
The U.S. Army Corps of Engineers and the city of Portland are working together in southeast Portland to restore a portion of Crystal Springs Creek to improve fish habitat and passage. The project reflects the Corps’ commitment to environmental stewardship by restoring ecosystems and improving watershed health.
The project is a partnership between the Corps and the city of Portland. It is authorized under Section 206 of the Water Resources Development act of 1996, which allows the Corps to partner with non-federal agencies to restore degraded aquatic ecosystems. Project costs are shared between the Corps (65%) and the city (35%).
Westmoreland Park restoration
Crystal Springs Creek is a tributary of Johnson Creek that flows through Westmoreland Park. Its naturally cool water and steady, year-round flow provide ideal fish habitat. Endangered salmon and trout species, including coho, Chinook and steelhead migrate through the creek to the ocean and back again to spawn.
The Corps, together with Portland Parks and Recreation and Environmental Services, begins work this summer to transform the existing concrete-lined duck pond into a wetland area through which Crystal Springs Creek will flow. The restoration will reduce water temperatures and improve habitat for threatened native salmon, and restore habitat for native waterfowl, amphibians and mammals. When the project is complete visitors will have a healthier park for people and native wildlife.
All in-water work will be accomplished from July 15 to August 31 to minimize impacts to migrating fish.
Tacoma Street culvert replacement
The Corps, together with the Bureau of Environmental Services, is replacing several culverts to improve fish passage. Culvert replacement is a key element of recovery of endangered juvenile salmon and trout species.
Construction preparations are underway to replace the culvert at S.E. Tacoma Street and S.E. 21st Avenue. The new 14 foot wide, natural-bottom culvert will replace the existing 4 foot diameter pipe culvert and improve fish passage and hydrology.
Early work to prepare the sites for summer construction included removing branches from select trees to avoid impacts to nesting migratory birds. These same trees will later be removed from the site before construction begins. The work on Tacoma Street requires removing four trees, some of which are already in poor health.
All in-water work will be accomplished from July 15 to August 31 to minimize impacts to migrating fish.
