The Portland Water Bureau and the Oregon Parks and Recreation Department are restoring key habitat for threatened salmon and steelhead at Dabney State Recreation Area this summer.
The Dabney Large Wood Placement Project is a stream habitat restoration project that will increase off-channel habitat in Springwater Creek, a tributary to the Sandy River. Juvenile salmon and steelhead will find refuge in the pools and gravel under the large logs that will be placed in the stream channel.
Once the project is complete, native trees and vegetation will be planted in the surrounding riparian areas.
Springwater Creek will be reconnected to its historic channel, which was blocked by a small landslide. Thirty logs will also be placed at 13 sites in the stream channel Previously, this stream had provided habitat for juvenile salmon and steelhead to spend the winter, out of danger from the fast moving water in the Sandy River. Log jams slow stream velocity, create resting areas, scour deep pools, offer cover for fish, increase nutrients, and provide homes for aquatic insects eaten by the fish.
- Logs will be placed in the stream channel using a helicopter on July 31, and August 1-2.
- Site construction and restoration will take place from July 17 through the first week of August.
This project is part of the City’s commitments under the Bull Run Water Supply Habitat Conservation Plan, a 50-year plan to protect and improve aquatic habitat in and around the Bull Run River while continuing to manage the Bull Run Watershed as a water supply for the City of Portland. Implementation of the projects defined in the HCP allows the City of Portland to operate the Bull Run Water Supply in full compliance with the federal Endangered Species Act and Clean Water Act.
The project is being conducted in partnership with the Oregon Parks and Recreation Department.
