Degraded Channel and Riparian Areas
Isolated Side Channels and Off-Channel Habitats
The Sieben Creek side channel reconnection project is on private property upstream of Sah-Hah-Lee Golf Course and downstream of the Rock Creek Confluence on the right bank of the Clackamas River. The project focuses on increasing channel complexity and connectivity which is currently inaccessible following the 1996 flood event. Constructing an apex jam will rack material and scour an upstream pool. Habitat structures throughout the channel would add structure, provide cover and initiate scour pools. Alcove enhancements at the downstream end of the project will include habitat structures to provide additional complexity.
