Section 1. Administrative
| Proposal title | Restoring connectivity to a floodplain wetland on Multnomah Channel |
| Proposal ID | 200709700 |
| Organization | Ducks Unlimited, Inc. |
| Short description | A creek will be realigned into its historic channel to maintain water in a wetland and run a fish ladder. A fish ladder will be installed adjacent to an existing water-control structure to increase connectivity between Multnomah Channel and the floodplain |
| Information transfer | This site is part of a long-term monitoring program designed to assess juvenile salmon use of seasonal floodplain wetland habitat, fish passage capability through water-control structures, fish passage opportunity relative to hydrologic connectivity with the floodplain, amphibian use, bird use, and vegetation response to holding water on the floodplain and riparian planting. Pre-project monitoring has been done as well as monitoring after a water-control structure was installed. The water-control structure temporarily decreased hydrologic connectivity between Multnomah Channel and the floodplain wetland. After this last phase of the restoration, monitoring will be done to ensure that this temporary problem is resolved. Results from this monitoring program have been reported in annual reports and distributed to a list of agency biologists and other interested individuals. Results have also been presented at various conferences including Oregon Chapter American Fisheries Society, Society for Ecological Restoration, and others. After the final phase has been completed and monitoring results of hydrologic connectivity, riparian re-growth, beaver activity, bird and other anumal and use assessed, a report will be written and more conference presentation will likely follow. Results from the last phase of this project will also be used as a case study in a project to write best management practices for use of water-control structures in floodplain wetlands where salmon are present. |

| Funding source | Related ID | Related title | Relationship |
|---|---|---|---|
| Other: DU | OR-12-2 | North Unit Sauvie Island | Enhancement of 400 acres of seasonal emergent and forested wetlands for waterfowl, native herpatiles, and juvenile salmonids. |
| Other: DU | OR-12-5 | Burlington Bottoms | This site is upstream of the proposed project. This site provides nearby off-channel habitat for rearing salmon, which they can access via a tidal channel. It also provides habitat for waterfowl. |
| Other: DU | OR-12-10 | Racetrack and Gay Lakes Enhancement | Two emergent wetlands on Sauvie Island; provide nearby migration and wintering habitat for waterfowl and shorebirds, and nesting/brooding habitat for waterfowl. |
| Other: DU | OR-32-1 | Smith and Bybee Wetlands | This site is on the Columbia Slough, which is located near the proposed project. This site provides resting and feeding and rearing habitat for juvenile salmon. This 1200 acre wetland also provides brooding, migration and winter habitat for waterfowl. There are native turtles and amphibians as well as otter and beaver present. |
| Other: DU | OR-32-2 | Multnomah South | This sites is immediately to the south of the proposed site. Crabtree Creek currently runs through this wetland. This creek was diverted to the south years ago but used to run through the north wetland. There is currently too much water running through the fishway to the south and not enough to the north. The propsed project is very much related to this site. |
| Other: DU | OR-76-1 | Elledge, North Sauvie Island | This site is near the proposed site and provides brooding, migration and winter habitat for waterfowl as well as habitat for other aquatic and terrestrial animals. |
| Other: DU | OR-107-1 | Scappoose Bottoms, Teal Slough | Enhanced 25 acres of wapato wetlands, restored 100 acres of tidal emergent and forested wetlands along Scappoose Creek to benefit ducks, geese, swans, numerous native hepatiles, and juvenile salmon. |
| Other: DU | OR-107-2 | Hogan Ranch Wetland Enhancement | This site is adjacent to Teal Slough, and has restored an additional 130 acres of tidal emergent and forested wetlands. |
| Other: DU | OR-126-1 | Enyart Bottoms | This site is immediately upstream of the proposed project. McCarthy Creek runs through a wetland and drains into Multnomah Channel. This site provides nearby off-channel habitat for rearing salmon and habitat for waterfowl. |
| Other: DU | WA-020-3 | Shillapoo Lake | This site is across the Columbia River from the proposed site but near enough for waterfowl to migrate back and forth on a daily basis. |
| Other: DU | WA-056-1 | Vancouver Lake | This site is across the Columbia River from the proposed site and provides nearby waterfowl brooding, miration and winter habitat. |
| Other: DU | WA-56-2 | LaCenter Bottoms | This site is three miles up from the mouth of the Lewis River, which drains into the Columbia River at the downstream tip of Sauvie Island. This site provides juvenile salmon winter and spring rearing habitat. It also provides brooding, migration and winter habitat for waterfowl. Beaver have been observed at this site. |
| Other: ODFW | 10800203000-10 | Spring Chinook Salmon in the Willamette and Sandy Rivers | ODFW PIT tags juvenile Chinook above Willamette Falls. We scan all salmonids for PIT tags during fish monitoring. |
| BPA | 200303600 | CBFWA Monitor/Eval Program | We will inform CSMEP of our fish monitoring activities. |

ISRP PRELIMINARY REVIEW (Jun 2, 2006)
Recommendation: Fundable
NPCC comments: This project will restore 100 acres of tidal wetland. Restoration of such areas in the Lower Willamette River is identified as a priority in the Willamette Subbasin Plan with significance for the restoration of Upper Willamette River spring Chinook, a listed species. CREP identified loss of wetlands and habitat as a key limiting factor. The US Army Corps of Engineers report on ecosystem approaches to habitat restoration also identifies a need to restore wetland habitat in the estuary, which is also tied to the ODFW Comprehensive Wildlife Conservation Strategy. A creek will be realigned into its historic channel to maintain water in the wetland. A fish ladder will be installed adjacent to an existing water-control structure to increase connectivity between Multnomah Channel and the floodplain. The proposal contains excellent photos and maps and a very persuasive description of the present conditions and need for resolution. The proposal does a good job referencing priorities in the Willamette Subbasin Plan. This is a collaborative project with Metro, who owns the land. In addition, collaboration and coordination with ODFW and City of Portland Environmental Services is also described. The project seems to fit well with ongoing wetlands restoration projects in this area. Information on wildlife population response to similar wetlands enhancement projects is effectively described. Good links to previous work that led to this project are given. The cost:benefit match is appropriate. Objectives are clearly linked to restoration actions in the subbasin plan, but the proposal could do a better job of being more specific (e.g. Objective 1 states the project will "Increase water supply to the north wetland..." How much? How will they measure potential benefit?). Work elements for the four objectives are clear quantitative descriptions, with work allocation among partners clearly described. Techniques are described generally. Monitoring of restoration effectiveness is one of the project's objectives. Monitoring of hydrologic and fish passage effects is well described in the four work elements. Specific details and timelines are given. Facilities are adequate. Existing collaborative relationships between Ducks Unlimited and other groups indicate they are an appropriate entity to conduct this project. Results from the last phase of this project will be used as a case study in a project to write best management practices for use of water-control structures in floodplain wetlands where salmon are present. As part of an ongoing monitoring program, results from the restoration activities at this site will be reported in annual reports distributed to agencies and presented at professional meetings. A final report will include a summary of best management practices for this type of restoration. Focal species are only generally stated as “all wildlife” but this type of restoration should have quite a significant benefit in restoring a relatively large acreage of lowland riparian and floodplain habitat and most native fish and wildlife associated with those habitats. Other species, not listed as focal species, are likely to benefit in the long-term from improved and expanded wetland habitat.
