Degraded Channel and Riparian Areas Degraded Channel Structure and Complexity
The proposed Clear Creek Confluence project is located at the confluence of Clear Creek and the Clackamas River. The project focuses on increasing physical habitat and complexity at the mouth of Clear Creek and an upstream alcove. 2.7 acres of invasive species removal will promote the recolonization of the property by native species. Replanting the area with native riparian vegetation will encourage understory development as well as provide future sources of large wood.
Large wood placement is proposed along 1,350 linear feet of channel. Placement includes 7 complexity log jams, 12 to 25 pieces each. Structures are proposed along river left, as well an apex jam and outlet jam.

Targeted Performance Measure

  • Large Wood Placement: 2,700.00 lf
  • Riparian / Floodplain Invasive Species Removal Area: 3.00 acres
  • Riparian / Floodplain Invasive Species Removal Length: 1,350.00 lf
  • Riparian / Floodplain Native Planting Area: 3.00 acres
  • Riparian / Floodplain Native Planting Channel Length : 1,350.00 lf
