Project Summary
Project Summary
Please provide a couple sentence summary of the proposal.
The Coastal Plan identified the high percentage of hatchery fish on the spawning grounds as a
primary factor limiting wild Elk River Chinook. This project will install weirs on Anvil and Rock
Creeks as part of a priority CMP strategy to reduce hatchery risk while maintaining harvest
opportunity.
Overall Project Goals
Describe the primary goals or outcomes of the entire project, including elements not requesting
funding from R&E.
Reduce the proportion of hatchery strays in Elk River through several actions required in the
CMP. This proposal is for one of those actions; weirs to remove hatchery Chinook.
Primary objectives of R&E funding
Please describe the measurable objectives for the R&E portion of the funding request.
1. Construct weirs that can withstand winter flows.
2. Trap the majority of fall Chinook and pass only unmarked Chinook upstream.
3. Analyze spawning ground survey data to determine stray rates above weirs.
Current Situation/Justification
Please describe the current situation and explain why this funding is needed.
The CMP, identified the high number of hatchery fish on the spawning grounds as a viability risk
to wild fall Chinook in Elk River. The average hatchery stray rate is 59%. The CMP identifies a
target of <30%. The plan identifies several actions to reach this goal: reduce hatchery smolt
releases, increase hatchery fish harvest, improve attraction into Elk River Hatchery, run the
hatchery trap longer, improve imprinting, support habitat restoration, and install weirs on Anvil
and Rock Creeks to remove hatchery fish. This proposal seeks to implement the last of these
actions – trapping hatchery fish in Anvil and Rock creeks. These streams were selected
because they support high numbers of wild and hatchery spawners, are located close to the
hatchery, and are hydrologically suitable for weirs. R&E funding will allow for the immediate
implementation of this action as intended in the CMP while providing time to secure long-term

sustainable funding should this effort be necessary to continue long-term. If the combination of
actions called for in the CMP are effective at reducing the stray rate below the 30% target, it
may be possible to discontinue this trapping, and/or increase the hatchery release back to its
historical level.
Recreation and Commercial Benefit
This project will provide benefits to:
Recreational fisheries
Commercial fisheries
Explain how this project will contribute to current (and/or potential) fishing opportunities, access, or
fisheries management.
Elk River fall Chinook contribute significantly to ocean commercial and in-river recreational
fisheries, with the hatchery fish comprising approximately 75% of the sport harvest in Elk River.
Due to the depressed nature of the wild Elk River fall Chinook population, harvest restrictions on
wild Elk River Chinook have been in place for a number of years. Recent Elk River Hatchery
releases were 325,000 fall Chinook smolts annually. The CMP called for the number of fall
Chinook smolts to be reduced 15% to 275,000 (this reduction began with the 2014 brood/2015
release) to help address the stray rate issue. This will result in a reduction in the number of
hatchery fish available to the fishery. Further reductions are called for if the stray rate goal is not
met by the 2020 return, which could reduce the fishery significantly more. This project is a key
action required under the CMP that could help reduce stray rates without reducing the fishery.
Achieving the overall reductions will require implementation of several actions (including the
weirs) outlined in the CMP. The weirs are the only component of the overall strategy that can
immediately reduce stray rates and begin to make substantial progress toward the goal.
Is this project part of an approved Salmon-Trout Enhancement Program (STEP) activity?
No
This project has been identified as a priority for:
Basin/regional
Identify any plan or other document that identifies this priority.
Coastal Multi-Species Conservation and Management Plan

This project is intended to benefit the following species:
Fall Chinook Salmon

Monitoring/Research
This project will be used to evaluate:
Hatchery releases and/or stray rates
Has this project been reviewed or developed by an individual with appropriate qualifications (i.e
ODFW biometrician, research professor)?
Yes
This project was vetted through the development of the CMP, where it is identified as part of a
multi-action strategy to reduce stray rates for Elk River Chinook.
Is this study critical to fishery management decisions?

Yes
Are weirs effective in removing hatchery fall Chinook from Anvil and Rock Creeks. Will reducing
the numbers of hatchery fall Chinook effectively reduce the overall stray rate of hatchery fall
Chinook.
Yes
If this pilot project is successful, weirs will be installed on an annual basis and permanent
funding will be identified.
Is there a plan to repeat this monitoring or research in the future?
Yes
If the project is successful, the project will be repeated in 2016.
Will the data be reported or published?
Yes
The results of the project will be included in the annual CMP report and posted on ODFW's
website.

Project Design and Description
Please describe in detail the methods or approach that will be used to achieve the project objectives.
Information on project design and implementation was gathered from other ODFW coastal
Districts that have operated trap and weir programs and from ODFW Information Report 96-5.
Schroeder, R.K. 1996. "A review of capture techniques for adult anadromous salmonids". Fall
Chinook and coho presence and distribution in Rock and Anvil Creeks comes from 45 years of
spawning ground surveys. Material and conceptual designs were vetted through Elk River
Hatchery personnel to obtain best material sourcing and pricing. This project will work
collaboratively with two other fall Chinook monitoring projects being conducted on Elk River.
Spawning ground surveys will be completed by the Mid-Oregon Coastal Production Region
Coded-Wire Tagging, Recovery and Escapement Estimation Crew. Fall Chinook salmon
captured at each weir will be analyzed for tags used by a 2015 the mark and recapture project.
Each weir will be made using pre-frabricated 10'x5'x 2" box aluminum frames bolted to A frames
on site. The box frames will be pre-drilled with 60 holes so that 1" diameter aluminum poles can
be inserted through the box frame to create the weir. Each weir section can be bolted to

adjoining weir sections to span the creek. Each weir may require 5 or 6 of these box frames and
associated A frames to span the creeks. Fall Chinook will be funneled into a live box made with
the same 2" aluminum box frame used for the weirs with a fyke built into the box.
The weir structure and live box will not be anchored into the substrate. Cables will be attached
to the weir and box and attached to trees outside the channel to keep the structure from being
pushed downstream by extreme flows.
The weirs will be installed around November 1, 2015 and completely removed by middle of
February, 2016.
The final weir design will be reviewed by ODFW engineering, before construction and
installation.
Engineering
Does the project involve capital improvement, engineering, site grading or other construction?
Yes
On ODFW land or managed by ODFW staff
Project Management and Maintenance
What is the life expectancy of R&E funded construction, structures, equipment, supplies, data or
fishery?
The weir and trap have a life expectancy of 10 to 15 years or more. Other Districts using similar
equipment are still using weirs and traps constructed 12 years ago. The fishery information and
project design, if successful, will be used on an annual basis.
Who is responsible for long term management, maintenance, and oversight of the project beyond
what is funded by R&E.
The weir and trap will be installed seasonally. When not in use, the weir and trap will be stored
at Elk River Hatchery. All minor repairs and miscellaneous replacement parts will be the
responsibility of the Gold Beach District Office.
Will the project require ongoing maintenance?
Yes
It is expected that minor damage will occur to the structure during extreme high flows, nuts and
bolts lost, or welds break, etc.
Is there a plan to collect baseline data and to conduct monitoring efforts to measure the effectiveness
of the project?
Yes
Spawning ground surveys have been conducted on Rock and Anvil Creeks annually since 1969.
The spawning ground survey project is independent of this proposal.
