Degraded Channel and Riparian Areas
Isolated Side Channels and Off-Channel Habitats
The project is located on 9.5 acres of Dahl Beach Park at the confluence of the Clackamas and Willamette rivers. Restoration actions included excavating and re-grading two interior basins and placing large wood at the inlets. The project provides important off-channel habitat for juvenile spring/fall Chinook salmon, coho salmon, and winter steelhead. The project included coordinating all activities with the municipal landowner, City of Gladstone, for this highly used and very visible park site. Construction activities were completed during the 2016 in-water work period. Additional work to restore native vegetation will continue through 2019.
