South Fork Clackamas River Habitat Restoration Project
Project Overview
Basics
South Fork Clackamas River Habitat Restoration Project
Implementation
After the devastating fires of 2020 the Mt Hood NF working with CRBC added 50 trees killed by during the fires to the lower 1000' of the South Fork Clackamas River. The project included constructing one 15 log apex log structure near the confluence of the SFK and mainstem Clackamas and tipping another 35 trees into the river. The largest tree was over 5 feet in diameter and 200 feet tall. Areas disturbed by the fire were treated for invasive weeds and replanted. Adding instream woody debris is a common strategy to increase habitat complexity, or alter the stream channel by reducing water velocity and increasing stream depth and pool frequency

Financials
Budget
| Comment: | The Project Title should be changed slightly-not sure how to do that; or how to delete other older proposed projects. The project design has morphed recently to include several smaller projects developed earlier in the FIP planning process. Now it is one big project that includes the small projects. |

| Note: | Due to the 2020 fires the project scope was changed from the mainstem Clackamas River to the South Fork Clackamas River. The project implemented was considered to be a good substitute by all parties involved, the USFS, PGE and ODFW. Constructing the SFK project resulted in substantial savings on project costs. |

• Adding instream woody debris is a common strategy to enhance fish populations (Stewart et al., 2006; Howson et al., 2012; Roni et al., 2015), and can increase habitat complexity, provide food or habitat for prey species, or alter the stream channel by reducing water velocity and increasing stream depth and pool frequency (Urabe & Nakano, 1998; Keim, Skaugset & Bateman, 2002).

Project Types
Project Types
Apex Wood Jam structures and (50) single logs are proposed within the project area to increase, rearing habitat, pool formation, spawning gravel deposition, channel complexity, hiding cover, low velocity areas, and floodplain function. Each structure would be placed in the channel below the bank full water level at the head of point bars locations that are naturally prone to accumulating large wood. The two structures are intended to recruit more wood during high flow events. Like the jams, single pieces create localized scour and pools, and provide escape cover habitat.
