CTWS Side Channel Reconnection
Implementation
The project demolished an unpermitted dam and soaking pools restoring fish passage in a side channel, built 6 apex and one deflector log structures along 1 mile of the upper Clackamas River to drive process based restoration and force water into 3 newly excavated side channels and 2 existing side channels. In total over 500 logs were imported to the site from areas burned during the 2020 fires with an additional 25 on site trees tipped. The new side channels created 1/2 mile of habitat providing excellent rearing habitat for juvenile salmonids, primarily coho and chinook. 7 acres was planted with over 20,000 native trees, shrubs and grasses by an indigenous lead contractor.

Focal Species
Focal Species
Bull Trout are active in this area according to USFWS. The addition of large wood to the mainstem and side channels will increase useable habitat by providing resting and foraging positions for fluvial adults migrating through the reach and the increase in side channel habitat will benefit juveniles that may be using the area for rearing and migrating
Coho are active in this area, with extensive spawning occurring upstream in the Big Bottoms area. The addition of large wood to the mainstem and side channels will increase useable habitat by providing resting and foraging positions and the increase in side-channel and off-channel areas will provide additional rearing and holding areas for juveniles
Chinook are active in this area with spawning occurring upstream in the Big Bottoms reach. The addition of large wood to the mainstem and side channels will increase useable habitat by providing resting and foraging positions and the increase in side-channel and off-channel areas will provide additional rearing and holding areas.
Lamprey are active in this area and increased habitat will directly benefit them. Also, dependent on what surveys find there maybe a lamprey reintroduction program above North Fork Dam.
Chinook are active in this area with extensive spawning occurring upstream in the Big Bottoms area. The addition of large wood to the mainstem and side channels will increase useable habitat by providing resting and foraging positions and the increase in side-channel and off-channel areas will provide additional rearing and holding areas.
Steelhead are active in this area with extensive spawning occurring upstream in the Big Bottoms area. The addition of large wood to the mainstem and side channels will increase useable habitat by providing resting and foraging positions and the increase in side-channel and off-channel areas will provide additional rearing and holding areas.

Notes
| 10/30/2020 1:37 PM | John Runyon | BPA holds a conservation easement to prevent the conversion of fish and wildlife habitat on the property to other land uses. BPA will also provide stewardship funds toward the maintenance of the property to the tribe. The Tribe will develop a management plan to guide the protection and enhancement of habitat and other resources on the property. The management plan will be reviewed by BPA for consistency with the purpose of the Conservation Easement. |

Project Protection Benefits C. Full protection to perpetuity 4. Process Based Restoration: Partial Restoration: iv v vi 5. Address Threats from Climate Change: Restoration Actions address climate change resiliency (i, iv) 6. Address threats from urbanization: A. It is protected by Mt. Hood national forest so there is no risk of ubanizations 7. Project Scale: a. V ( when taking into consideration side channel and mainstem work). b. iii 8. Project constraints and risks. C. There are few to no feasibility constraints. Only consideration is trespass. |
