1. GENERAL INFORMATION AND MANAGEMENT BACKGROUND

On September 1, 2021, the U.S. District Court for the District of Oregon issued an interim injunction that requires the Corps to implement interim injunction measures intended to improve conditions for fish passage and water quality at several Willamette Valley Project (WVP) dams for the benefit of Upper Willamette River (UWR) spring Chinook salmon and UWR winter steelhead salmon during the interim period until the completion of the reinitiated Endangered Species Act (ESA) consultation. The Court assigned an Expert Panel to define the implementation plans of specific measures, which were required to “provide meaningful research, monitoring, and evaluation (“RM&E”) of the interim measures.”

Further, the injunction mandates that the Corps “fund and/or carry out RM&E to evaluate the effects of the interim measures on UWR Chinook salmon and UWR steelhead.” On February 28, 2022, the Expert Panel submitted its proposed “long term” plan for the RM&E to accompany the interim injunction measures for the remainder of the duration of the injunction.

2. SCOPE OF WORK

This is a firm-fixed price Task Order for This is a firm-fixed price Task Order for collecting biological information regarding the downstream passage of juvenile Chinook salmon and winter steelhead including the reporting of results. This Task Order consists of the following actions

Rotary Screw Trap monitoring at multiple locations throughout the WVP to evaluate downstream passage.

Bulk marking of juvenile Chinook salmon via Passive Integrated Transponder (PIT) tagging services to provide information on the passage and migration timing of juvenile Chinook salmon entering and exiting the reservoirs of multiple Corps facilities in the Willamette River basin.

The reporting of information collected herein, along with results of other related RM&E measures (e.g., other RST sampling and downstream PIT tag detectors), and previously collected information collected throughout the WVP under previous conditions (e.g. Romer et al. 2013- 2017; Keefer et al. 2012, 2013) will be synthesized to evaluate implementation of certain measures prescribed under the “long term” RM&E plan.

3. LOCATION OF SERVICES

Requirements of this Task Order will occur within the Willamette Valley throughout the Corps Willamette Valley Project (WVP). Activities will occur throughout the Willamette Valley Project (WVP) in the North Santiam, South/Middle Santiam, South Fork McKenzie, and Middle Fork Willamette River subbasins including Fall Creek (Figure 1).

REQUIREMENTS

For the purposes of this Task Order, the following information is provided, by sub-basin, for context in performing Task Order requirements. See PERFORMANCE STANDARDS AND REQUIREMENTS for Task Order performance requirements.

North Santiam River Sub-basin: Detroit and Big Cliff Dams

Description of Operations for Downstream Fish Passage and Water Temperature Management (Abbreviated from Implementation Plans & Long Term RM&E Plan):

The Corps will modify Detroit Dam operations during the fall drawdown and winter months once the reservoir elevation is less than 100 feet over the turbine intakes (elevation 1450 -1500 feet).

The turbines will only be operated at Detroit Dam during the day (unless otherwise dictated by downstream water temperature conditions), while a non-turbine outlet will be prioritized to pass flow at night (from dusk until dawn), with no turbine operation (no power generation) during this period except for Station Service if needed for emergencies or for downstream TDG management.

To reduce downstream water temperatures during the fall while Chinook salmon are spawning and their eggs incubating, the Corps will provide downstream water temperature management throughout late spring, summer, and fall at Detroit Dam through strategic use of the spillway, turbines and upper and lower ROs. Spillway operations will start when the reservoir reaches spillway crest elevation (El. 1541.0 ft) and continue until the reservoir is drafted below the spillway crest. From there, a combination of turbine and upper and lower RO discharges will be implemented until water temperature management is no longer possible due to reservoir turnover. With adaptive management, the spill ratio will be adjusted so water temperatures (as measured at the USGS gage downstream of Big Cliff) can best meet targets.

The Corps will operate multiple spillway gates at Big Cliff Dam to spread total flow across the spillway and reduce TDG levels below Big Cliff Dam. The operation occurs when the Corps is operating the Big Cliff spillway (e.g., high flow events over the 3200 cfs turbine capacity). The Corps will monitor TDG downstream and identify the extent that TDG criteria is met under this operation.

Management Purpose and Biological Goal: <Excerpt from Long Term RME Plan> The overall goal is to establish self-sustaining populations of spring-run Chinook salmon and, while not currently present above Detroit Dam, winter steelhead upstream of Detroit Dam. The objective of this measure is to provide volitional passage for juvenile Chinook salmon at Detroit and Big Cliff dams in spring with high passage efficiency, and high immediate and long-term survival. In addition, the management of water releases from Detroit and Big Cliff dams is intended to maintain downstream temperatures within specified temperature criteria, while maintaining acceptable level of TDG.

The target fish for the fall passage operations would be subyearling Chinook salmon that entered the reservoir in the previous winter–spring and reared through summer in the reservoir, and subyearling Chinook salmon that enter the reservoir in summer and fall.

The primary target fish for the spring operations would be Chinook salmon fry and subyearlings that enter the reservoir in late winter and spring, and yearlings that either enter the reservoir in late winter and spring (small number) or entered the reservoir in the previous winter-fall and remained through the winter.

The intent is to determine if changes in dam operation improve downstream fish passage conditions at Detroit and Big Cliff dams compared to previous operations as a result of implementing this operation. The metrics of interest include juvenile spring Chinook salmon migration timing into the reservoir, migration timing through the reservoir, passage timing, passage size and condition, passage rate and survival.

South Santiam River Sub-basin: Green Peter Dam and Foster Dam

South Santiam River Sub-basin: Green Peter Dam

Description of Operations for Downstream Fish Passage and Water Temperature Management (Abbreviated from Implementation Plans & Long Term RM&E Plan):

Initiate a drawdown of Green Peter Reservoir in the fall, so as to achieve the targeted elevation of 780 ft. by winter. Inter-seasonable adjustments will be necessary and modeling results should be considered a general guideline. Discharge during drawdown will likely range between 3,000 and 4,000 cfs, except as may be required by flood risk management (FRM) operations or during Chinook spawning. From September through mid-October, Green Peter and Foster Dam outflows will be managed to maintain flows between 1,500 and 3,000 cfs in the South Santiam River downstream from Foster Dam to protect Chinook spawning, to the extent possible.

The targeted elevation of 780 ft. is approximately 35 feet over the regulating outlets (ROs) at Green Peter Dam. As soon as the reservoir is drawn down below minimum power pool (El. El.

887 ft.), the Green Peter powerhouse will cease operation and all water will be discharged through the ROs. The reservoir will be held at or near El. 780 ft. for approximately one month unless FRM dictates otherwise.

In the spring, the Corps will release water from the spillway once the Green Peter Reservoir reaches El. 971 ft. Spill will be carried out continuously until May 1 or for at least 30 days, whichever is longer. At least two different spill strategies will be tested in a block study: (1) continuous (24/7) spill through a minimum gate opening of 1.5 ft. and (2) nighttime spill through a 3–4 ft gate opening one hour before sunset to one hour after sunrise. Additional spill may continue throughout the summer for water temperature management. This will be adaptively managed and may change from year to year, depending on climate and hydrologic conditions.

Operations in spring 2023 are summarized in the respective Green Peter Dam implementation plan and may be modified by mutual agreement of the Corps and NMFS as warranted.

Management Purpose and Biological Goal: <Excerpt from Implementation Plans and Long Term RM&E Plan> The overall goal [of the Green Peter Dam drawdown] is to establish a self-sustaining population of spring Chinook salmon upstream of Green Peter Dam. The goal of this drawdown operation measure is to provide volitional downstream passage and survival for juvenile spring Chinook salmon and steelhead through Green Peter Reservoir and past Green Peter Dam in the fall with high passage efficiency and high immediate and long-term survival. The target fish for the fall operations would be salmon fry and subyearlings that entered the reservoir in the previous winter–spring and reared through summer in the reservoir, and subyearlings that enter the reservoir in summer and fall. The number and proportion of salmon fry that remain and rear in the reservoir will depend on the passage effectiveness of spring operations under Measure 12a.

The number and proportion of stream-reared summer and fall migrants after adult Chinook salmon are outplanted will be determined through RM&E activities under this measure (traps upstream of reservoir) and Measure 12a (traps upstream of reservoir and life history sampling in streams upstream of the reservoir.

South Santiam River Sub-basin: Foster Dam

(Abbreviated from Implementation Plans & Long Term RM&E Plan):

Starting after Labor Day weekend, Foster Reservoir will be drawn down to a forebay elevation of

620–625 ft. by October 01. From October 1–December 15 the Foster spillway will be operated from one hour before sunset to one-half hour after sunrise; turbine unit 1 (only) will be operated at station service to reduce/balance TDG levels created by the spill operation. Spill gates should be opened to a 1 ft. gate opening; outflow amounts will be dictated by reservoir elevation. Flows will be spread across multiple gates if necessary. During the day, the Foster turbine units will be operated from one-half hour after sunrise to one hour before sunset, with full generation. The spillway will not be used to discharge water during this time unless required for flood risk management.

Starting 01 February maintain Foster Reservoir at minimum conservation pool (El. 613 ft.)

prioritizing spillway operation from one hour before sunset to one-half hour after sunrise.

During the day (one-half hour after sunrise to one hour before sunset, the Foster turbine units will be operated with full generation. The spillway will not be used to discharge water during this time unless required for flood risk management. On 15 May the Corps will begin refilling Foster Reservoir using stored water from Green Peter Reservoir and South Santiam River inflow targeting full pool of Foster Reservoir by Memorial Day Weekend. From May 16 – June 15, operations at Foster Dam will continue as described above.

From June 16 – late July, the focus of Foster operations will transition to downstream water temperature control. The fish weir will be installed in one spillbay and operated continuously (day and night) to improve downstream water temperatures and upstream migration. Outflows from the fish weir are approximately 300 cfs.

Management Purpose and Biological Goal: <Excerpt from Implementation Plans and Long Term RM&E

The overall goal [of the Foster operations] is to establish self-sustaining populations of spring Chinook salmon and winter steelhead upstream of Foster Dam. The goal of this spill operation is to provide improved downstream fish passage and survival for juvenile spring Chinook salmon and steelhead through Foster Reservoir and past Foster Dam [including operating Foster Dam in a manner that reduces reservoir holding time and increases downstream passage survival for juvenile salmonids]. A primary objective of the delayed refill operation is to provide conditions for volitional passage of juvenile Chinook (especially fry, including fry that pass Green Peter Dam) as well as winter steelhead.

The target fish for the fall operations would be salmon fry and subyearlings that entered the reservoir in the previous winter–spring and reared through summer in the reservoir, and subyearlings that enter the reservoir in summer and fall. Juvenile winter steelhead (age 0 and age 1) are present in the reservoir and have been observed in high numbers in the forebay.

Although few steelhead were caught downstream of the dam in previous years, fall spill operations could provide passage opportunities for these fish. Passage would also be provided for juvenile salmon migrating past Green Peter Dam.

The target fish for the spring operations would be salmon fry and subyearlings that enter the reservoir in winter–spring and juvenile salmon that reared through fall-winter in the reservoir.

Juvenile winter steelhead pass the dam in the spring as age 2 smolts. Age 1 juvenile steelhead are also present in the reservoir and may benefit from passage measures. Passage would also be provided for juvenile salmon migrating past Green Peter Dam.

South Fork McKenzie River Sub-basin: Cougar Dam

(Abbreviated from Implementation Plans & Long Term RM&E Plan):

The Cougar Reservoir will be drawn down to elevation 1505 ft. from early November through

December 15. Once Cougar Reservoir is drawdown to El. 1571 ft. and below, the regulating outlets (ROs) will be operated at night, and powerhouse (i.e., generate) during the day. From El.

1532 ft. to El. 1505 ft., the ROs will be prioritized at all times to discharge water from the reservoir. On December 16, the Cougar Reservoir refill will begin and use the ROs during nighttime hours until El. 1532 ft. is reached. The diversion tunnel will not be used during this special operation.

After the winter drawdown of Cougar Reservoir, initiate reservoir refill to the minimum conservation pool El. 1532 on December 16. Hold the reservoir to El. 1532 ft. until 01-March. On 01 March, begin to draft Cougar Reservoir to El. 1520 ft., targeting this elevation on 01-April.

The intent is to provide an increased downstream flow signal that encourages outmigration of fish from the reservoir. Delay refill from 1520 ft. as long as possible, while maintaining a high likelihood of reaching El. 1571 ft. by July 1. For the entirety of the spring operation, the ROs should be prioritized at night when passage is highest. Generation is allowed during the day.

Note: additional powerhouse discharges may be required depending on rain events, inflow conditions, or downstream water quality values. Use adaptive management to determine the refill starting date. The decision on when to initiate refill will be made by the Federal agencies’ Flow and Water Quality Management Team (FWQMT) considering hydrologic data from April and May, including snowpack, average weekly inflows, and extended Water Supply forecasts from the NW River Forecast Center, and fish migration data from trapping upstream and downstream of the reservoir and dam.

After the winter drawdown of Cougar Reservoir (IM 14), initiate reservoir refill to the minimum conservation pool El. 1532 on December 16. Hold the reservoir to El. 1532 ft. until 01-March. On

01-March, begin to draft Cougar Reservoir to El. 1520 ft., targeting this elevation on 01-April.

The intent is to provide an increased downstream flow signal that encourages outmigration of fish from the reservoir. Delay refill from 1520 ft. as long as possible, while maintaining a high likelihood of reaching El. 1571 ft. by July 1. Use adaptive management to determine the refill starting date.

Management Purpose and Biological Goals: <Excerpt from Implementation Plans and Long Term RM&E

The metrics of interest include spring Chinook juvenile passage timing, passage size and condition, passage rate and survival.

The objective of the fall measure is to provide volitional passage for juvenile Chinook salmon at

Cougar Dam during fall and early winter with high passage efficiency, and high immediate and long-term survival.

The target fish for the fall operations would be salmon fry and subyearlings that entered the reservoir in the previous winter–spring and reared through summer in the reservoir, and subyearlings that enter the reservoir in summer and fall. The number and proportion of salmon fry that remain and rear in the reservoir will depend on the passage effectiveness of spring operations under Measure 15.

Determine if downstream fish passage conditions at Cougar Dam have improved compared to previous operations as a result of implementing this operation. RM&E should be prioritized to understand active outmigration versus reservoir use (i.e., “movers” and “stayers”).

The target fish for the spring operations would be salmon fry and subyearlings that enter the reservoir in late winter and spring, and yearlings that either enter the reservoir in late winter and spring (small number) or entered the reservoir in the previous winter-fall and remained through the winter. The number and proportion of juvenile salmon in the latter group will depend on the passage effectiveness of fall-winter operations under Measure 14.

Determine if downstream fish passage conditions at Cougar Dam have improved compared to previous operations as a result of implementing this operation. Results will used to determine whether structural improvements/modification to Cougar’s regulating outlets will be necessary to ensure safer fish passage. RM&E should be prioritized to understand active outmigration versus reservoir use.

Middle Fork Willamette River: Dexter Dam, Lookout Point Dam, Hills Creek Dam

Middle Fork Willamette River Sub-basin: Fall Creek Dam

(Abbreviated from Implementation Plans & Long Term RM&E Plan):

Extend the drawdown of Fall Creek reservoir from December 1 through January 15. Ensure that

Fall Creek Reservoir hits streambed (El. 780-785 ft.) by December 01. Hold at this elevation through January 15. On January 16, begin refill to El. 700 ft. and hold at this elevation (+/- 3 ft.)

for the spring passage operation (Injunction Number 20), except as needed to provide downstream flood damage reduction or sediment management. The Corps may need to provide flushing flows to clear the RO tailrace of sediment.

Fall Creek Reservoir will refill from streambed level to El. 700 ft starting January 16 and will be held at that level until March 15, except as needed for flood control or sediment management.

Refill, following rule curve, will begin on March 16.

The overall goal is to establish a self-sustaining population of spring Chinook salmon upstream of Fall Creek Dam. The goal of this drawdown operation is to provide downstream fish passage and high survival for juvenile spring Chinook salmon through Fall Creek Reservoir and past Fall Creek Dam.

The target fish for the fall operations would be salmon fry and subyearlings that migrated downstream in the previous winter–spring and reared through summer in the reservoir, and subyearlings that enter the reservoir in summer and fall (before drawdown). The number and proportion of salmon fry that remain and rear in the reservoir will depend on the passage effectiveness of spring operations under Measure 20.

The target fish for the spring operations would be salmon fry and subyearlings that migrate downstream in late winter and spring, and yearlings that migrate downstream from winter through spring.

[The purpose of the fall/winter measure is to] extend the opportunity for juvenile Chinook salmon to pass through the reservoir and past the dam in the late fall and early winter. The metrics of interest for biological monitoring include juvenile Chinook salmon passage timing, passage rates, and passage survival.

The primary objective of [the spring] measure is to provide safe and timely passage for young-of-year juvenile Chinook salmon that enter Fall Creek reservoir such that they may avoid extended reservoir residence and express their natural life-history strategy. The metrics of interest include juvenile Chinook salmon passage timing with an emphasis on fry.

Middle Fork Willamette River Sub-basin: Lookout Point and Dexter Dams

(Abbreviated from Implementation Plans & Long Term RM&E Plan):

The Corps anticipates, beginning in 2023, to draw down the Lookout Point Reservoir to elevation

750 ft. in the winter while prioritizing use of the regulating outlets (ROs) during this time.

Drawdown likely to be initiated in late summer / early fall, using a combination of the spillway, regulating outlets and powerhouse. Once the reservoir is below minimum conservation pool, the ROs will be used exclusively to pass outflows.

Starting as early in March as possible, and once Lookout Point Reservoir elevation reaches 2.5 feet over spillway crest (El. 890 ft.), continuous, ungated spillway releases will be implemented at Lookout Point Dam, along with continuous gated spill at Dexter Dam. Spill operations will be implemented continuously (24/7) for at least 30 days at both projects. After the 30-day continual ungated spill operation, transition to a nighttime, gated spill operation with generation during the day at Lookout Point and Dexter for as long as water is available and downstream conditions allow.

When water temperatures as measured at the USGS gage downstream of Dexter Dam near 60°F, operate the Lookout Point ROs to reduce downstream water temperatures.

The overall goal is to establish a self-sustaining population of spring Chinook salmon upstream of Lookout Point Dam. The goal of the [spring measure] is to provide volitional passage for juvenile salmon at Lookout Point Dam in spring with high passage efficiency, and high immediate and long-term survival. Safe, timely, and effective passage includes minimizing juvenile residence time in Lookout Point reservoir. Objectives of the spring spill are twofold: first to reduce residence time in Lookout Point Reservoir. This will subsequently reduce the risks of predation and copepod infestation by increasing migration rates through the reservoir. Second, to increase passage survival at the dams. At a larger scale, an objective of the spring spill is to increase survival of juvenile salmon below Dexter Dam.

The target fish for the spring operations would be salmon fry, subyearlings, and stream-reared yearlings that enter the reservoir in late winter and spring; and subyearlings that entered the reservoir in the previous winter–fall and remained through the winter.

Intent of spring operations is to provide operations that minimize reservoir rearing time and reduce turbine passage for juvenile Chinook salmon at Lookout Point and Dexter dams.

Determine if downstream fish passage conditions through Lookout Point Reservoir and at Lookout Point and Dexter dams have improved compared to previous operations as a result of implementing this operation. Compare passage of juvenile Chinook salmon under 30-day continuous spill to that under nighttime spill. RM&E should be prioritized to understand active outmigration versus reservoir use.

General research questions are:

What is the travel time of juvenile salmon from reservoir entry to the forebay during conditions of spring spill and how does it compare between continuous spill and nighttime spill, and to previous years with limited or no spill?

What is the passage rate and passage survival of juvenile salmon during spring spill and how does it compare between continuous spill and nighttime spill, and to years with limited or no spill?

The metrics of interest include migration timing into the reservoir, migration timing through the reservoir, size at passage, dam passage rates and passage survival.

Middle Fork Willamette River Sub-basin: Hills Creek Dam

(Abbreviated from Implementation Plans & Long Term RM&E Plan):

Once Hills Creek Reservoir is drawn down below El. 1460 ft., operate the regulating outlets daily from 6:00 PM to 10:00 PM. This operation is expected to be implemented from approximately December 1 through March 1.

The overall goal is to establish a self-sustaining population of spring Chinook salmon upstream of Hills Creek Dam. The goal of this drawdown operation is to provide downstream fish passage and high survival for juvenile spring Chinook salmon through Hills Creek reservoir and dam.

The intent is to operate Hills Creek Dam in a manner that reduces reservoir holding time and increases passage survival for juvenile salmonids. The metrics of interest for biological monitoring include juvenile Chinook salmon passage timing, passage rates, and passage survival.

Adult Chinook salmon were not outplanted upstream of Hills Creek Dam in 2021. Therefore, effectiveness of the measure cannot be fully evaluated for this cohort in winter-spring 2022 (for fry) or winter-spring 2023 (for fall migrants, spring yearling migrants, and reservoir residents).

However, juvenile salmon from previous outplants would be present and studies could be conducted in winter-spring 2023 with experimental releases.

Throughout this PWS terms are defined as follows:

Acceptable Quality Level (AQL): Acceptable Quality Level equals the performance standards listed in Section 6.0. The Contractor must re-perform all unsatisfactory work unless excused by the COR.

Columbia Basin PIT Tag Information System (PTAGIS) - The Columbia Basin PIT Tag Information System (PTAGIS) was implemented in 1991 to manage and serve PIT tag data collected in the Columbia Basin. PTAGIS develops software used to collect and contribute PIT tag data; validates, stores and makes those data available for download via the PTAGIS website (www.ptagis.org);

and operates large scale PIT tag detection sites throughout the Columbia Basin. In 2002, the scope of the PTAGIS program expanded to include resident and semi-anadromous stocks of rainbow and cutthroat trout, bull trout, lamprey, sturgeon, and other species.

Contracting Officer (KO): The Government employee who is authorized to enter into, administer, and/or terminate contracts and make related determinations and findings.

Contracting Officers Representative (COR): An individual designated in accordance with subsection 201.602-2 of the Defense Federal Acquisition Regulation Supplement and authorized in writing by the Contracting Officer to perform specific technical or administrative functions.

The COR is not authorized to make any commitments or changes that will affect price, quality, quantity, delivery, or any other term or condition of the contract.

Contract Discrepancy Report (CDR): A written record of unsatisfactory performance by the Contractor as observed by the COR.

Long-term RM&E Plan: Willamette Project Interim Injunction Measures Research Monitoring and Evaluation Plan developed by the US District Court assigned Expert Panel comprised of two of Plaintiffs’ experts, two NMFS biologists, two Corps employees, and two “ad hoc” Federal experts to define the implementation plans of specific measures.

Passive Integrated Transponder Tag (PIT Tag) - Passive Integrated Transponder (PIT) Tags are electronic, implantable microchips used in biological applications and have been used to monitor the movement and behavior of anadromous salmonids in the Columbia River Basin (CRB) since 1987. PIT tags are an RFID tag typically measuring 8 to 12 mm long coded with one of 35 billion unique codes. PIT tags used in the CRB can be automatically detected and decoded in situ – eliminating the need to sacrifice, anesthetize, handle, or restrain fish after the initial tagging event. PIT Tags used herein shall be of the most recent and highest performing RFID tag model(s) currently on the market in the 8 mm size for fish <65mm or 12mm size for fish >65mm, encapsulated in biocompatible glass and provide 100% unique identification. PIT tags and detection equipment used herein shall meet Columbia Basin PIT Tag Information System (PTAGIS) standards as well as be ISO 11784 and 11785 compliant (e.g., APT12 or equivalent).

Rotary Screw Trap (Screw Trap; Trap; RST) - A rotary screw trap consists of a fish collection device having a screw blade (i.e., rotary cone) driven by water current acting thereon which, in conjunction with a porous enclosure (e.g., stainless steel mesh or screen), confines fish and/or debris for passage to a discharge site (i.e., live box). Typically, the device consists of a large frustoconical shaped cone (5 or 8 feet in diameter) which, with the screen, confines fish and/ or debris for travel to the outlet end of the screen. Adjustable means (e.g., lifting A-Frame) coupled to the screen permit lifting of the screen relative to the water surface. A receptacle (e.g., live box) into which fish and/or debris is deposited are supported by the buoyant support structure (i.e., floatation pontoons).

Willamette Valley Project (WVP) - The Portland District operates 13 dams in the Willamette

River basin (i.e., ‘Operating Projects’ or ‘Project’). Each dam contributes to a water resource management system that provides flood risk management, power generation, water quality improvement, irrigation, fish and wildlife habitat and recreation for the Willamette River and many of its tributaries. For purposes of this Task Order, the WVP typically refers to the Corps’ Operating Projects in the North Santiam, South Santiam, South Fork McKenzie, and Middle Fork Willamette River sub-basins. This includes Detroit Dam (DET) and Big Cliff Dam (BCL) on the North Santiam River, Green Peter Dam (GPR) and Foster Dam (FOS) on the South Santiam River, Cougar (CGR) Dam on the South Fork McKenzie River, Fall Creek Dam (FCR) on Fall Creek (tributary of Middle Fork Willamette River) and Dexter Dam (DEX), Lookout Point Dam (LOP), and Hills Creek Dam (HCR) on the Middle Fork Willamette River.

9. OVERVIEW OF PERFORMANCE STANDARDS AND REQUIREMENTS APPLICABLE TO

ALL TASKS

General Requirements

The Contractor shall regularly coordinate field work with the Contracting Officer Representative (COR) and WVP Operations staff to ensure timely communication of activities with Corps staff.

o Other entities are marking juvenile salmonids in the region with elastomer (or similar) tags including at rotary screw traps; the Contractor shall coordinate with the COR on marking strategies to avoid any conflicts.

The Contractor is responsible for proper deployment, placement, inspection, and maintenance of all necessary equipment to deploy, anchor, and maintain all equipment associated with this Task Order.

o The Corps will provide ground space for tanks and associated equipment on Corps property. Where possible, the Corps will provide standard 110v electrical service and water supply at no cost to the Contractor. However, the Contractor shall be prepared to hold fish independent of Corps services and WVP operations (i.e., without Corps electrical power and plumped water supplies) as the Corps WVP facility operations can change unexpectantly at any time.

Sampling shall be consistent with previous studies where applicable (e.g., Romer et al. 2014- 2017, Monzyk et al. 2015, Keefer et al. 2012, 2013; Kock et al. (2019a, 2019b), FPC 2012) and be conducted consistently at all sites for comparison of results across sites, sub-basins and sample periods.

Passive Integrated Transponder Tags (PIT Tags) - PIT Tags used herein shall be of the most recent and highest performing RFID tag model(s) currently on the market in the 8mm and 12mm size, encapsulated in biocompatible glass and provide 100% unique identification. PIT tags and detection equipment used herein shall meet Columbia Basin PIT Tag Information System (PTAGIS) standards as well as be ISO 11784 and 11785 compliant (e.g., APT12 or equivalent).

Sourcing of PIT tags for each Task, and pre-loading of injection needles and trays if desired, is the responsibility of the Contractor.

The Contractor shall submit detailed information for deployment of equipment for use under this Task Order including anchoring details as part of work plan submittals (Task 1). Deployment and anchoring hardware shall not be drilled into Corps permanent structures (i.e., concrete, dam appurtenant); use of alternate anchoring hardware is required.

The Contractor is responsible for regularly evaluating conditions and making adjustments to equipment, supplies and materials used as part of this Task Order, as warranted to meet Task Order requirements.

The Contractor is responsible for any boats, boating services, and deployment/retrieval of boats needed for proper placement, inspection, and maintenance of equipment necessary to perform requirements under this Task Order.

Many of the field sites are in areas that may be difficult to reach during the winter months due to winter weather conditions including snow and ice. It is the Contractor’s responsibility to have the equipment necessary for reaching field sites (e.g., snowplow, snowmobiles, atv/utv with snow tracks) as required to meet Task Order requirements as some access roads are not maintained during the winter.

The Lookout Point and Green Peter reservoir areas may be difficult to reach during the deep draw down periods once the reservoirs are drafted below the existing boat ramps. It is the Contractor’s responsibility to have the equipment necessary for reaching field sites as required to meet Task Order requirements.

The contractor is responsible for physical access to the work site(s). The Contractor shall carry a CB radio in all vehicles for communication with local road users. In particular, there is active logging activities occurring in the Middle Santiam sub-basin and the use of CB radios is required for communication with local log trucks when accessing the head of Green Peter Reservoir area on the Middle Santiam River arm.

Government Supplied Hatchery Fish General Requirements

Hatchery fish shall be provided by the Corps from hatcheries in the respective Willamette Valley sub-basin (hatchery fish) or OSU surrogate program (Corvallis, OR; Alsea, OR) (surrogate fish).

Fish will primarily come from the respective Willamette Valley hatcheries, with the surrogate program providing limited numbers of fish if/when available (e.g., when necessary to utilize surplus surrogate fish not utilized for other studies).

The Contractor shall regularly coordinate fish requirements with the COR and ODFW prior to pickup and following pickup. The Contractor shall provide documentation of fish transfers (i.e.

pickups) to the COR and ODFW and maintain detailed records of transfers by pickup date, source, brood year, and numbers relative to total hatchery fish requirements by Brood Year.

While the Corps will provide the source of hatchery fish for the Contractor’s use, the Contractor will be responsible for all details associated with performing requirements of the Task Order (e.g., picking up fish from the source at the hatcheries, marking, holding, and releasing fish).

Hatchery fish will be adipose fin clipped according to the hatchery’s normal marking schedule (generally during the summer) and therefore fish may not be adipose fin clipped at time of pickup by the Contractor. Prior to release, all hatchery/surrogate fish shall be adipose fin clipped at minimum, unless permitted otherwise by ODFW and NMFS, and marked with a secondary mark if required for purposes herein. Therefore, the Contractor herein will be required to conduct any necessary marking, including adipose fin clipping, prior to release of hatchery fish if not done by the hatchery. Fish sourced from the surrogate program will not be marked in any way by the surrogate program; the Contractor herein is responsible for all required marking of hatchery fish sourced from the OSU surrogate program including adipose fin clipping.

Hatchery fish being supplied herein may be intermixed with fish with Coded Wire Tags (CWT).

The Contractor is responsible for sorting fish with a CWT back to the respective hatchery at the time of pickup (i.e., fish with CWTs are not being provided for Task Order requirements herein).

Fish with a CWT must be sorted and returned to the hatchery before fish are transported off-site (i.e., fish cannot be returned to the respective hatchery once taken offsite). This will primarily occur in the South Santiam sub-basin and to some extent at Dexter Fish Facility/Hatchery (primarily with yearling Chinook), but may occur at all hatcheries.

While physical space and river water supplies may exist at some locations (e.g., Cougar Dam tailrace, hatcheries), the Contractor shall be prepared to conduct the necessary fish holding, tagging and marking in a self-sufficient, self-contained manner, using Contractor supplied tagging station(s) and water supply system(s). The Contractor will not be allowed to mark/tag fish at the OSU surrogate facility (i.e., fish must be picked up and marked/tagged offsite).

Hatchery Chinook fry are typically available starting in the late winter (approximately March depending on sub-basin conditions such at water temperatures), subyearling Chinook are typically available late spring to December, and yearling Chinook are typically available January to March. Following coordination with the COR and ODFW, the Contractor herein shall be responsible for picking up hatchery/surrogate fish during periods of availability and holding (as/where necessary) to meet Task Order requirements.

o For the Middle Fork Willamette sub-basin, hatchery yearling Chinook must be picked up by 01 February for the respective brood year, if being held at the Dexter Fish Facility, as the Dexter hatchery (Dexter Fish Facility) will be shutdown annually for construction during the mid-February to mid-May periods (i.e., no MF Willamette hatchery yearling Chinook are available during these periods from Dexter Dam).

o South Santiam yearling Chinook held at South Santiam hatchery (at Foster Dam) must be picked up by 28 February annually as the final South Santiam yearling Chinook release occurs 01 March.

o Hatchery juvenile Chinook may be held at hatcheries in alternate sub-basins – for example, Willamette Hatchery has been holding some hatchery juvenile Chinook for RM&E needs herein in recent years.

Bulk/Batch Marking General Requirements

The Contractor shall uniquely mark each release group with 8 mm (45-64mm) or 12 mm PIT tags (>65mm) in order to uniquely identify each release group and to uniquely distinguish each release group herein from run-of-river Chinook captured throughout the WVP and that are elastomor (VIE) marked both herein and under separate contract (e.g., via rotary screw traps).

Mark each release group at least 2-3 weeks prior to release with sufficient numbers marked to account for mortality prior to release and for control group(s).

The Contractor shall monitor tag injury, tag retention to document long-term visibility of tags or marks, and mortality (including long term mortality including injury from tagging) by:

o Holding a sample of marked fish groups for observation with a target of 3-5% and minimum of 50 fish per mark/tag group (i.e., mark and hold an additional 3-5% of each mark/tag group).

o Holding observation groups for 2 weeks post-marking.

o Sample group can be part of the release group if sufficient holding time for release group at large is achieved.

Hold fish consistent with hatchery management practices in regard to factors including maximum holding densities, water supplies (volumes, pass through flows, water quality), feeding (schedule and food types), and disease treatment (e.g., USACE 2016; USACE WFOP). Fish shall be held in low densities consistent with established hatchery holding/rearing and transport protocols (i.e., ≤5 lbs of fish per 1 gpm inflow and ≤0.5 lbs per 1 gallon of water) (e.g., USACE

WFOP, USACE FPP).

The Contractor shall be responsible for setup and maintenance of fish marking and holding stations within the Willamette Valley Project to complete tasks throughout this task order including PIT tagging, and holding of juvenile spring Chinook. These facilities shall be placed on Corps-owned and managed property (e.g., at a dam) with specific locations to be identified and selected in coordination with the COR -or- at ODFW hatchery facilities with permission of the respective hatchery manager (to be obtained and maintained by the Contractor herein).

Contractor’s facilities shall be self-contained and maintained by the contractor herein.

Facilities shall be setup to accommodate holding juvenile spring Chinook as…
