Land uses that Impair Riparian Condition or Reduce Streamflow
Cow Creek subbasin drains 871 acres of primarily industrial and residential land. The project would address upstream passage by removing to failed culverts near its confluence with the Clackamas. The project would also include floodplain and mainstem fringe restoration and add large wood debris to the tributary and mainstem. Conditions would be improved for Coho, Lamprey, and Spring Chinook.
Targeted Performance Measure
- Stream Habitat Accessible
Focal Species
- Coho
- Pacific Lamprey
- Spring Chinook
