As stated in Section 9.b., inadequate passage conditions for both upstream and downstream migrants were the primary contributor to the extirpation of salmon and decline of steelhead in the Umatilla Basin. Although many passage improvements have been implemented there are still critical times of the year when inadequate migration conditions exist. The objective of the project is directly related to the goals and objectives stated in the Subbasin Summary by assisting in the restoration of salmon and steelhead populations in the Umatilla River by increasing the tributary survival of migrating adults and juveniles.
There are two specific strategies in the Subbasin Summary which identify needed actions directly related to the Fish Passage Operations Project. Strategy 4 (Protect, enhance, and restore instream flows to improve passage conditions and increase rearing potential for anadromous and resident fishes in the Umatilla River Basin.) identifies three actions specific to the project. Action 4.1 is to continue operations of the Umatilla Basin Project, Action 4.2 is for continuing flow enhancement measures to improve passage conditions, and Action 4.7 is to continue trap and haul salvage operations as needed during low flow periods. The project is also involved in a number of other actions listed under Strategy 4.
Strategy 5 (Improve fish passage conditions at all man-made passage impediments for resident and anadromous upstream and downstream migrants.) lists four actions in which the project is directly involved. Action 5.1 is to implement screening of all diversions, Action 5.3 is for operating and maintaining all fish passage facilities, Action 5.4 is to ensure adequate passage conditions exist, and Action 5.6 is for continuing trap and haul operations. The project is also involved in other actions listed under Strategy 5.
The Fish Passage Operations Project is also directly involved in Strategies 6, 7, 9, 12, 14, and 16. For Strategies 6, 7, and 9, the project is the primary broodstock collection source for the various artificial production programs listed. The project broodstock collection activities also fall under Strategy 12, Action 12.1. The project is solely responsible for Strategy 14, Action 14.1, the monitoring of adult returns at Threemile Dam. Under Strategy 16, Action 16.1, the project provides data to mainstem Columbia River monitoring projects, most specifically the Fish Passage Center gas bubble disease monitoring and headburn study and the University of Idaho mainstem adult migration monitoring study.
The project goal of assisting in the restoration and rebuilding of salmon and steelhead populations in the Umatilla Basin is directly related to the Council’s mandate to protect, mitigate, and enhance fish and wildlife affected by development and operation of the hydropower system. Though the project falls under the Columbia Plateau Ecological Province for which specific objectives and strategies will be adopted later, the project does address the Council’s Basin-level biological objectives listed in the 2000 Fish and Wildlife Program. More specifically, the project objective of increasing tributary survival directly addresses the three items listed in Section III.C.2.a.1. (Anadromous fish losses); halt declining population trends, restore natural populations, and increase adult runs.
The Fish Passage Operation project is also indirectly involved in a number of the RPA actions listed in the NMFS 2000 FCRPS Biological Opinion. As stated previously, the project contributes data to studies identified under Actions 107 and 108 (Fish Passage Center gas bubble disease monitoring and headburn study and University of Idaho mainstem adult migration monitoring study). Although not specifically identified in Action 149 or 151, the project is directly involved in activities associated with those Actions and listed under Section 126.96.36.199 (Actions Related to Tributary Habitat).

Project: 198805302 – Design and Construct Umatilla Hatchery Supplement
Build incubation/juvenile rearing capabilities at the existing South Fork Walla Walla spring chinook adult holding and spawning facility to rear spring chinook for acclimation/release in the Umatilla Basin.
In the 1980's, CTUIR and ODFW began implementing the comprehensive Umatilla Fisheries Restoration Program. An integral part of that effort was artificial propagation of salmon and steelhead for release into natural production areas. Umatilla and Little White Salmon hatcheries currently produce spring chinook smolts for release in the Umatilla River. Although the existing program is achieving success in returning adults for natural production, broodstock acquisition and harvest, these hatcheries do not provide for the full production required to achieve the Umatilla Basin spring chinook restoration goals and objectives as defined in the Draft Umatilla Subbasin Summary (CTUIR et al., 2001). An additional 515,000 smolts are needed to achieve these objectives. Numerous completed and ongoing passage, flow enhancement, and habitat improvement efforts in the Umatilla Basin are expected to greatly enhance the benefits of the proposed hatchery project.
The Umatilla Hatchery Satellite Facility for spring chinook adult holding and spawning already exists at the proposed South Fork Walla Walla River project site. The existing facility includes land, water intake and effluent settling pond that is sized to accommodate the proposed new production. Project master planning, NEPA, final designs, and projct review by the NPPC are scheduled for 2001 and 2002. Construction is scheduled for 2002. Upon completion, the entire facility will be operated under the existing Umatilla Hatchery Satellite Facilities O & M project #8343500.

Umatilla Basin Natural Production Monitoring and Evaluation
M&E Project will monitor the natural production success of fish produced under this project.
Relationship to Existing Goals, Objectives and Strategies:
This proposal has been identified in Section 7.4L of the 1994 Council Fish and Wildlife Program as part of NEOH. The need for additional spring chinook production was recognized in the Umatilla Hatchery Master Plan approved by the Council in 1990.
Facilities constructed under this project will be an essential part of the comprehensive Umatilla River Fish Restoration Plans developed by CTUIR and ODFW in cooperation with the Council, BPA, Bureau of Reclamation, NMFS, and various irrigation districts and private landowners. The project will increase smolt production, improve smolt quality, and will help to increase smolt to adult survival and will directly increase adult returns of spring chinook salmon to the upper Columbia and Umatilla Rivers which is consistent with the Council’s Fish and Wildlife Program, US v. OR Columbia River Fish and Wildlife Plan and the Pacific Salmon Treaty.
This project also addresses the Council’s basin-level biological objectives listed in the 2000 Fish and Wildlife Program. More specifically, the project objective of assisting in spring chinook restoration by producing more smolts and ultimately more returning adults directly addresses Section III. C.2.a.1 (Increase total adult salmon and steelhead runs above Bonneville Dam by 2,025 to an average of 5 million annually in a manner that supports tribal and non-tribal harvest). Also, in Section III. D.4, the primary strategy for artificial production states that artificial production can be used to compliment habitat improvements and replace lost salmon and steelhead.
As stated in Section 9.b., artificial propagation is a key element in the comprehensive Umatilla fisheries restoration program and is required in order to achieve spring chinook objectives in the Umatilla Subbasin Summary (CTUIR et al., 2001). The objective of spring chinook adult returning to the mouth of the Umatilla River is 8,000. Current returns are approximately 2,000 – 4,000 annually. Based on smolt-to-adult return rate approximately 0.55% for Carson stock spring chinook produced at Bonneville Hatchery and released into the Umatilla River, approximately 2,800 adult returns to the Umatilla River will result from the additional 515,000 spring chinook production. These adults will contribute towards achievement of natural production, broodstock, and harvest objectives in the Umatilla Basin as well as the Fish and Wildlife Program goals.
Strategy 6 (continue to supplement the recently re-introduced spring chinook population with a hatchery program consisting of Carson stock to provide natural production and harvest) in the Subbasin Summary specifically identifies an action related to this hatchery proposal. Action 6.2 calls for release of additional 515,000 spring chinook smolts from acclimation facilities into historic spring chinook habitat in the upper Umatilla River Basin to achieve the remainder of the spring chinook objectives.
The successes already being achieved in the Umatilla River to return once-extirpated salmon to a tributary to contribute towards natural spawning, broodstock collection, and Indian and non-Indian harvest objectives is being called a rare success in todays challenging times for Columbia River fisheries resources. This proposal will seek to add more benefit to this existing success story.
Reviewers question the potential for interactions with listed steelhead. These issues will be addressed through NWPPC processes.

Project: 198902401 – Evaluate Juvenile Salmonid Outmigration and Survival in the Lower Umatilla River Basin.
Assess migration patterns, abundance, survival of hatchery and natural juvenile salmonids in Umatilla basin using PIT tag technology; monitor lamprey and resident fish; assess affects of river variables on fish migration; devel op adult interrogatation
The Umatilla Basin Fisheries Restoration Program includes multi-faceted projects to enhance and reestablish salmonid and lamprey populations in the Umatilla River and restore functioning aquatic ecosystems. The goal of the Outmigration and Survival Study is to determine and strengthen the overall effectiveness of the fisheries restoration effort by evaluating the outmigration success of hatchery and natural juvenile salmonids and natural Pacific lamprey in the lower Umatilla River. The project also proposes to expand on existing PIT-tag interrogation capabilities to assess adult returns. Through project activities, knowledge is gained for improved management of hatchery, river, canal, and transport operations. Trends in natural production, survival, and responses of biological communities to flow enhancement strategies are monitored. Collaboration with other basin projects supplements and augments various databases and M&E efforts. Specific project objectives from 2002-2004 are to: 1) conduct PIT-tag interrogation operations at West Extension Canal (RM 3.7); 2) design and implement PIT-tag interrogation capabilities at the east-bank ladder at Three Mile Falls Dam; 3) determine abundance, migration timing, and in-basin survival of tagged juvenile salmonids representing various hatchery rearing, release, and acclimation strategies; 4) evaluate relative survival between transported and non-transported tagged juvenile salmonids; 5) evaluate migration timing and abundance, and monitor trends in natural production of salmon, steelhead, and Pacific lamprey; 6) assess condition, health, size, and growth of hatchery and natural migrants; 7) investigate effects of river, canal, and fishway operations on anadromous and resident species; 8) document temporal distribution and diversity of resident fish species at trap sites; and 9) participate in planning and coordination activities in the basin and disseminate results.

Relationship to Existing Goals, Objectives and Strategies:
This project is an integral part of achieving the fisheries restoration goal in the Umatilla River basin (Figure 1). It is needed to fulfill and address the many needs identified in various planning documents. The Umatilla Subbasin Summary (Saul et al. 2001) specifically identifies the need to "monitor and evaluate the productivity, abundance, distribution, life history, and biological characteristics of anadromous and resident fish and relationships with instream and riparian habitat conditions within the Umatilla Basin to assess the success of management strategies" (Fish Strategy 14). Through biological monitoring, information is provided for updating the subbasin plan or for developing a new Plan, for improving management and conservation of natural populations, and for assessing the effectiveness of hatchery rearing and release strategies. It also supplements natural production monitoring of lampreys and salmonids. The ability to remotely detect tagged fish in the lower Umatilla River provides invaluable information on in-basin migration parameters and survival of tagged fish; this information is supplemented by tag detections at lower mainstem dams. The increased sophistication of detection capabilities has also minimized personnel requirements and increased monitoring efficiency. It can also be used
as a prototype system for other tributary interrogation sites. Although the Umatilla Basin Fisheries Restoration Program fourth year of work (1997-1998) was scheduled to be the last, strong support for continued monitoring was given by basin managers to provide additional opportunity for obtaining valid survival estimates using PIT-tag technologies. With the use of a remote PIT-tag detection system at West Extension Canal in 1999, 2000, and 2001, the project has been able to obtain improved estimates of trapping efficiency, abundance, and survival of tagged fish groups without stressful handling (Ehlers et al. 2001, Knapp et al. in progress).
Continued monitoring in 2002 - 2004 will provide additional years of remote PIT-tag detection information and biological monitoring data to be applied toward answering the critical uncertainties associated with juvenile salmon and Pacific lamprey. Continued monitoring would provide additional years of data beyond the 1996 floods and the 2001 drought. In addition, natural production is increasing; lower-river monitoring of some species groups is the only means of estimating their abundance. The advent of adult interrogation systems at Columbia River hydropower facilities provides the impetus to implement similar capabilities in the lower Umatilla River. Specific rationale for continued monitoring is described below.
Proposed project objectives are to: 1) conduct PIT-tag interrogation operations at West Extension Canal (RM 3.7); 2) Design and implement PIT-tag interrogation capabilities at Three Mile Falls Dam ladder facility; 3) determine migrant abundance, migration timing, and in-basin survival of PIT-tagged juvenile salmonids representing various hatchery rearing, release, and acclimation strategies; 4) evaluate relative survival between transported and non-transported (in-river) PIT-tagged subyearling migrants; 5) determine migration timing and abundance of tagged natural fish, and monitor trends in natural production of salmon, and steelhead, and Pacific lamprey; 6) assess condition, health, size, and growth of hatchery and natural migrants; 7) investigate effects of river, canal, and fishway operations, and environmental conditions on fish migration and survival; and, 8) document temporal distribution and diversity of resident fish species at trap sites; and, 9) Participate in planning and coordination activities in the basin and disseminate results.
These objectives relate directly and indirectly to objectives, strategies, and actions specified in the Umatilla Subbasin Summary (Saul et al 2001), the 2000 FWP (NPPC 2000), and the recent NMFS Biological Opinion (NMFS 2000). Monitoring information from and activities related to this project are beneficial for making informed decisions regarding fisheries restoration in the Umatilla River. Products of this project will directly contribute to:
evaluating critical uncertainties about survival potential and production success of natural stocks, including outplanting strategies
understanding species-specific life history information of anadromous and resident fish
providing information on species-specific migration timing and characteristics
assessing the effectiveness of hatchery rearing, acclimation, and release strategies
assessing the effectiveness of flow enhancement strategies
acquiring knowledge on lamprey migrations and population status
acquiring information on juvenile migrant condition and health
assessing impact of avian predation on juvenile migrants
understanding environmental effects on salmonid migration and survival
acknowledging response of anadromous populations to habitat restoration efforts
understanding benefits to survival for transported juvenile fish
assessing the feasibility of incorporating adult PIT-tag interrogation capabilities at Three Mile Falls Dam
Indirectly, this project would contribute to:
improving management and conservation of natural populations
estimating smolt-to-adult survival for natural steelhead
improving hatchery strategies
reestablishing sport and Tribal fisheries in the Umatilla River
increasing adult returns
One of the primary objectives in the Umatilla basin is to restore natural production of fall and spring chinook salmon as well as coho salmon for off-site mitigation of Columbia River salmon stocks (Saul et al. 2001). For natural populations of salmon, steelhead, and lamprey, lower-river monitoring provides additional information on life history characteristics and production that supplements information obtained in the upper river by the Umatilla Tribes. Continuation of upriver PIT tagging of natural production groups in 2002 (Natural Production M&E) will allow estimates of in-basin abundance and survival with lower river monitoring. Abundance estimates for natural fish sheds light on problems within the early life history stages and helps to establish realistic estimates of production capacity, given current flow regimes, water quality, and river uses. Supplemental tagging of natural species in the lower river also presents opportunity to determine smolt-to-adult survival for natural steelhead and chinook, using PIT tags. Numbers of natural steelhead juveniles sampled at West Extension Canal in the past (>2,000 fish/season) have been more than adequate to tag for a determination of SARs given adult interrogation capabilities in the mainstem.
With the implementation of HB3609, information pertinent to salmonid life histories, natural and hatchery fish interactions, and migrant abundance estimates is needed to perform the necessary risk/benefit analysis of supplementation to natural fish populations. In addition, the foreseen need for a revised subbasin plan will require up-to-date information on each species. ESA concerns regarding summer steelhead also warrant a more complete understanding of steelhead life history in the Umatilla basin. Migration monitoring can supply the information needs for many management policies and programs, especially in relation to instream flow needs. For example, collection of scale samples and length measurements from natural migrants is part of the monitoring protocol. These samples and measurements help to clarify life history patterns, migrant ages, and rearing profiles.
A new supplementation strategy being implemented by the Tribes (outplanting of adults) for fall chinook salmon is showing some success in enhancing the number of juvenile migrants (Knapp et al. 2000). This supplementation strategy will be continued in the future and perhaps expanded to include spring chinook salmon. In 1999, lower-river monitoring detected increased production of natural spring chinook salmon (Ehlers et al. 2001), which may not have been evident at upriver traps; similar results were obtained in 2000 (Knapp et al. in progress). With the substantial spawning escapement of spring chinook salmon in 2000 (> 4,000; CTUIR and ODFW 2000) and the projected high escapement in 2001 (3,000-4,000; ODFW 2000), production of subyearling and yearling migrants is anticipated to be very good in the next few years (given suitable water conditions). Production of coho salmon from natural escapement is also increasing as adult returns improve and production areas expand (e.g., into McKay Creek). To monitor these supplemented and escapement productions, a lower river trapping operation is
The Umatilla Hatchery Master Plan (CTUIR and ODFW 1990) advocates adaptive management in its goal toward increasing Umatilla River production. The artificial production program relies, in part, on research and monitoring information obtained from this project's activities to assist in making decisions regarding hatchery practices associated with rearing, release or acclimation of specific species. Hatchery practices can be evaluated as to their potential success or failure in the short-term with in-basin monitoring information. This information is used by hatchery managers and researchers to further fine-tune or adjust hatchery practices to optimize production and produce a better product which will ultimately affect adult returns, harvest opportunities, and affect decisions on which species is best suited for Umatilla Hatchery and the Umatilla River.
Development of Hatchery Genetic Management Plans (HGMPs) for production programs in the Umatilla River will require knowledge of species-specific survival and behavior factors (performance indicators) to address performance standards. Performance indicators are measured partly through outmigration monitoring of the juvenile stage. For example, health and survival of migrants, migration timing, natural production abundance estimates, and residualism or holdover of steelhead are determinable from activities contained within this project proposal.
There also exists the potential for improving detection capabilities at Three Mile Falls Dam for both juvenile and adult salmonids. Adult returns of PIT-tagged fish are expected to increase in the coming years. As PIT-tag technology improves, flatplate interrogation of upstream migrants at the east-bank fishway becomes a possibility. Detection of downstream juvenile migrants in the fishway would supplement detections at the west-bank bypass. This project would continue investigating the feasibility of flatplate interrogation at the east-bank ladder for detecting tagged juvenile and adult fish passing through the ladder, with installation and monitoring planned for 2003.
Major limiting factors for salmonid production in the Umatilla basin are poor water quality and quantity. Water quality (temperature, sediment load, chemical concentration) is being addressed in the TMDL monitoring program (DEQ) and the Umatilla Watershed Assessment recently completed by Washington State University. Water quantity is influenced by natural flows, enhanced flows, and irrigation needs. Target flows for natural and hatchery salmonids are currently being debated and tested in conjunction with flow enhancement projects within the Umatilla basin (Umatilla Basin Water Exchange Project). A comprehensive database of information on flow needs for fish is required to justify increases in target flows, particularly during summer months. An understanding of flow needs for and flow affects on fish at specific times of the year is developed from migration monitoring information. Extension and provision of flow in the lower river into the summer months in 2000 may repeat itself in the years to come. For the first time, flow (45 cfs) from McKay Reservoir was provided to the lower river throughout summer in 2000, allowing the operation of both juvenile and adult passage facilities at Three Mile Falls Dam. We observed continual movement of resident fish and subyearling chinook salmon (Knapp et al. In preparation). Future monitoring would further assess the effects of these flow strategies on fish movement and life histories and ascertain the benefit to late migrants. Efforts to enhance natural fall chinook and coho salmon and Pacific lamprey require the understanding of flow benefits and needs for these fish during their mid-summer rearing and migration. Temperature effects on fish are also critical in June and July; monitoring elucidates the nature of those effects.
In 1999, NMFS listed Umatilla River summer steelhead as a threatened species as part of the Middle Columbia Evolutionary Unit (ESU) under the Endangered Species Act (ESA). A Biological Assessment was compiled on effects to federally listed species from the continued operation and maintenance of the Bureau of Reclamation's Umatilla Irrigation Project (Torretta 2000). The proposed project provides migration information to assess instream flow needs for these listed fish.
Much of the work results achieved within this project provide ancillary information for fisheries management and research, including effectiveness of new marking techniques (photonic marking), videography, and use of remote PIT-tag detection at canal bypass facilities. Project staff have developed expertise in PIT-tag technology that would have potential benefits for future work in-basin and out-of-basin. The installation of 134kHz PIT tag detectors at Columbia River dams has provided the impetus to continue using this improved technology in the Umatilla Basin for answering critical uncertainties related to natural production success and hatchery effectiveness. Combined detections of PIT-tagged fish in the Umatilla and at Columbia mainstem dams augment the database for determining minimum survival or survival potential. Work in FY2001 fine-tuned the efficiency of the PIT-tag detection system in the lower river. Future potential exists to apply PIT-tag interrogation technology to the adult fish ladder at Three Mile Falls Dam once prototype systems are designed and tested. Interrogation at this point would detect tagged returning adults and tagged juvenile migrants. Several more years of effort at remote PIT tag monitoring in the Umatilla basin would allow a continuation of and improvement in monitoring to address the many critical uncertainties still left unanswered.
Specific strategies and actions listed in the recently developed Umatilla Subbasin Summary are either directly or indirectly associated with this project proposal. Actions that this project proposal directly addresses include:
Action 4.8 Continue to refine knowledge of flow limited stream reaches and results of flow enhancement efforts to address remaining needs. (Proposal Objs. 1, 7)
Action 7.2 Assess monitoring and evaluation results (on fall chinook supplementation) to determine appropriate program changes to achieve objectives. (Proposal Obj. 5)
Action 10.3 Monitor for increases in larval abundance (of Pacific lamprey), juvenile outmigration, and adult returns. (Proposal Obj.2, 5)
Action 13.2 Evaluate performance of yearling spring chinook salmon reared at various stations and released in the Umatilla River. (Proposal Objs. 1, 3)
Action 13.4 Evaluate juvenile migration performance of fall chinook salmon released in varying locations in the Umatilla River. (Proposal Objs. 1, 3)
Action 13.5 Evaluate performance of yearling and subyearling fall chinook releases in the Umatilla River. (Proposal Objs. 1, 3)
Action 13.7 Monitor performance of summer steelhead reared in Michigan raceways. (Proposal Objs. 1, 3)
Action 14.3 Evaluate juvenile anadromous smolt production, survival, and migration timing by operating smolt collection facilities as necessary. (Proposal Objs. 1, 3, 5)
Action 16.3 Conduct monitoring of migratory fish to determine survival rates, timing, and distribution outside the basin. (Proposal Objs. 1, 3, 5)
Indirectly, this proposal addresses the following Actions:
Action 3.11 Monitor and evaluate efforts to protect, enhance, and restore instream and riparian habitats. (Proposal Obj.5)
Action 13.9 Monitor and evaluate the health and disease status of adults and juveniles for all Umatilla hatchery programs. (Proposal Obj. 6)
Action 14.5 Conduct biological surveys to monitor and evaluate anadromous and resident fish distribution, abundance, condition, habitat use, life history. (Proposal Obj. 8)
Although not specified in the Subbasin Summary, this project would also provide M&E related to the following Actions:
Action 4.2 Continue and build upon instream flow enhancement measures in the mainstem Umatilla River to improve passage for upstream and downstream migrant resident and anadromous salmonids and lamprey in the subbasin. (Proposal Obj. 7)
Action 4.7 Continue trap and haul salvage operations when necessary during low flow periods. (Proposal Obj. 4)
Action 5.4 Monitor river conditions and operation of passage facilities to ensure that adequate passage exists and implementadjustments as necessary to ensure efficient passage. (Proposal Obj. 7)
Action 9.2 Design and implement a comprehensive study to assess whether supplementation activities in the subbasin have been effective in rebuilding natural steelhead while maintaining their genetic structure and long-term viability. (Proposal Obj. 2)
Not addressed in the Subbasin Summary, but identified as a need from previous ISRP reviews of Umatilla Basin projects, is the estimation of smolt-to-adult survival of natural summer steelhead. Smolt-to-adult survival for natural steelhead has not been previously determined through the Natural Production M&E project primarily due to lack of mainstem interrogation systems for adult fish and inability to tag sufficient numbers of juveniles. As adult interrogation systems are developed on the mainstem (and possibly in-basin at Three Mile Falls Dam), an opportunity arises to make this estimate by tagging natural steelhead (and chinook) migrants in the lower river through the proposed project. (Proposal Obj. 5). This tagging effort would supplement upriver efforts conducted by the Natural Production M&E project, and ensure sufficient numbers of fish are tagged are reliable SARs.
This project proposal addresses both objective components of the 2000 FWP. Monitoring describes responses of populations to habitat conditions in terms of abundance, productivity, and life history diversity (biological performance) and describes the environmental conditions experienced by those populations (environmental characteristics). Specifically, the proposal would meet several elements within the FWP program. All aspects of the project relate to the Research, Monitoring, and Evaluation program and are relevant to the Scientific Foundation and Framework. Ecosystem response and evaluation, as ascribed in the FWP, are part of this project's objectives as related to natural anadromous and resident fish populations. Objectives for biological performance that are relevant to this project include anadromous and resident fish losses. Monitoring of artificial production strategies (chapter 4) are also tied to many of this project's objectives.
The proposed project also addresses the RPA of Research, Monitoring, and Evaluation within the NMFS Biological Opinion. Monitoring areas pertinent to the proposal include population status monitoring, environmental status monitoring, and effectiveness monitoring. Population Status Monitoring: Determining areas occupied by juvenile salmonids and spawning adults, assessment of population status (abundance, trend, distribution, variation), reviewing status through time. (Proposal Obj. 5). Environmental Status Monitoring: Assessment of environmental influencespotentially affecting salmonid populations, determining change through time, and determining associations between environmental attributes and salmonid population status. (Proposal Objs. 7).
Effectiveness Monitoring: Assessment of intended effects of management actions on aquatic system and response of salmonid populations to those effects. (Proposal Objs. 1, 2, 3, 4, 5, 6, 7,8).
Specific RPA Actions to which the proposed project responds are:
Action 183: Habitat Effectiveness Monitoring – assess management actions related to attainment of instream flows and compliance with water quality standards. The project proposal specifies tasks that will monitor salmonid response to flow enhancement strategies and monitor water clarity in the lower river.
Action 184: Hatchery Effectiveness Monitoring - assess hatchery reforms and practices partially through monitoring of size, age, health, and smolt quality, as well as release locations, timing, and life stages of hatchery fish. The project proposal specifies tasks that will monitor condition and health of hatchery and natural migrants, determine length-frequency distributions, assess migration parameters and life history characteristics, and estimate survival of production groups.
The Hydropower Action to install adult PIT-tag detectors at FCRPS projects (Action 192) to determine, in part, SARs for listed species and steelhead kelt survival rates is relevant to the pursuit of adult interrogation capabilities in the lower Umatilla River at Three MileFalls Dam (Proposal Obj. 2) for the same purposes.
