The Portland Water Bureau and Metro are restoring key habitat for threatened salmon and steelhead at Oxbow Regional Park this summer.

2017 Project Poster

The Oxbow Engineered Log Jam Projects are stream restoration projects that will increase habitat for native fish in newly created sidechannels in 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 channels. Once the projects are complete, native trees and vegetation will be planted in the surrounding riparian areas

The first log jam was constructed in summer 2017. The second one will be constructed this summer, 2018 and work began June 18. Work will occur primarily on weekdays between 7 a.m. and 5 p.m., but some weekend and evening work might be necessary.

Please observe posted trail and area closed signs.

To ensure public safety, some areas within the park will be closed until the end of September. You will notice fencing, barricade tape and signage to alert visitors to the closures. The east side trail that is accessed from Gordon Creek will be closed weekdays and some weekends during construction.

You will notice excavators, dump trucks, pumps and other heavy equipment working on site throughout the summer. This equipment will access the site from Gordon Creek Road.
