Hydro project This project mitigates for damages caused by the following federal dams: Bonneville, The Dalles, and John Day dams on mainstem Columbia River
This project is a follow-up to the project to evaluate the loss of juvenile salmon due to passage through screening and bypass facilities at Umatilla River diversion canals and at fish ladder facilities. Non-biological products included the construction of numerous migrant traps. Minor subsequent tasks relevant to passage evaluation have been included in current research objectives. Current research developed out of the need to enlarge the scope of evaluating juvenile salmonid passage success (migration and survival) to the basin as a whole and to supplement and compliment other ongoing monitoring and evaluation projects. Project is currently in its third year of implementation.
Biological results achieved
Measurable biological outcomes include bypass efficiencies at differing canal operations and diversion rates; velocities at canal and ladder facilities; video documentation of juvenile fish passage at Three Mile Falls Dam; migration rates, timing, duration, and magnitude (time of day and day) for naturally and hatchery produced species of juvenile salmonids and brand groups of hatchery species; estimates of migrant abundance of each salmonid species passing Three Mile Falls Dam; determination of fish condition, smoltification indices, and length frequency distributions through time; determination of partial life history characteristics and lower river rearing for natural salmonids; relationships between migration characteristics and environmental variables (river flow and temperature); survival indices for hatchery released fish and marked natural fish; documentation of piscivorous and avian predators; information on composition of fish species during trapping at Westland Canal, and on salmonid injury and survival during and after transport. Seasonal presence of resident fish species and their life stages.
Project reports and papers
The following reports are a result of this project: Annual progress reports for 1995 and 1996 (in preparation) on Evaluation of Juvenile Salmonid Outmigration and Survival in the Lower Umatilla River Basin. Previous annual reports from Passage Evaluation Study (Evaluation of Juvenile Fish Bypass and Adult Fish Passage Facilities at Three Mile Falls Dam, Umatilla River 1990; Evaluation of Juvenile Fish Bypass and Adult Fish Passage Facilities at Water Diversions on the Umatilla River 1992, 1993, 1994, 1995). Project completion report for Passage Evaluation Study (1997).
Adaptive management implications
Based on previous year's results and knowledge gained, approaches to trap efficiency tests, video monitoring, trap capture, and fish marking have been modified. Findings on migration parameters, bypass efficiencies, fish condition, ladder passage, and the presence of wild salmonids in the lower river can be applied toward management of river, canal, and passage facility operations and water release and flow enhancement strategies to improve outmigration, passage, survival, and rearing conditions for juvenile salmonids. Survival results may necessitate a change in approach to fisheries restoration efforts to increase effectiveness. Alteration of hatchery rearing and release strategies is partly based on outmigration and survival results for specific strategies. Information on natural production in the lower river will assist managers in determining natural production potential or limitations. Successful natural production enhancement efforts for summer steelhead are contingent on understanding life history characteristics of natural and hatchery stocks. Information on predators could facilitate predator control measures to increase salmonid survival. Results of transport tests will help improve transport operations and conditions. Results from pathological analysis of migration mortalities contribute to understanding in-river disease dynamics for specific species and stocks of fish. Observations of juvenile fish behavior at ladder diffusers and measurements of velocity could affect a change in ladder operations or structures. Effectiveness of feasibility studies on photonic marking and remote detection could alter marking strategies and provide additional migrational information.
Results of this project will clarify the success of outmigration survival for hatchery and natural stocks and contribute to an understanding of how survival could be improved. Good survival is critical toward fisheries restoration efforts in the Umatilla Basin and in the system-wide doubling goal.
Specific measureable objectives

2. Determine migration parameters, migrant abundance, and survival of hatchery-released spring and fall chinook salmon, coho salmon, and summer steelhead in the lower Umatilla River; determine above for specific rearing and release strategies of Umatilla production groups.
3. Determine migration parameters, life history characteristics, migrant abundance, and survival of naturally-produced juvenile salmonids migrating within the lower Umatilla River.
4. Determine species composition, condition, and total weight of collected fish at Westland Canal during trap and transport operations.
5. Investigate relationships between river flow/temperature and migration parameters of hatchery and natural fish.
6. Evaluate cumulative injury to hatchery and natural salmonids emigrating through the lower Umatilla River; determine contributing factors of fish disease and mortality.
7. Determine biological and environmental variables that may affect in-river survival for juvenile salmonids; determine prevalence of avian and piscivorous predators and document presence of resident fish species.
8. Evaluate condition and post-transport mortality of juvenile salmonids subjected to crowding, loading, and transport from Westland Canal to the mouth of the Umatilla River.
9. Document fish behavior at the fish exit gate at Three Mile Falls Dam using an underwater video camera; estimate juvenile fish passage at the viewing window, using video.
10. Participate in planning and coordination activities associated with anadromous fish passage in the Umatilla basin.
11. Evaluate the feasibility of using Photonic tags and hand and remote detectors to monitor migrating juvenile salmonids in the Umatilla basin.
1. Uncertainty of handling affects on survival of juvenile salmonids during collection; fish are necessarily handled to derive biological information.
2. Uncertainty of trap efficiency marking on survival and behavior of released fish which may detrimentally impact good trap efficiency estimates.
3. Risk of detrimental affects to resident fish species during collection.
4. Uncertainty on river flows and/or diversion rates during migration monitoring which could curtail collections of migrating fish.
5. Risk of using photonic marks, affecting fish and human health; risk of installing remote detetors at ladder facilities which could impact adult passage.
6. Uncertainty on successful marking of hatchery production groups affecting monitoring or rearing and release strategies.
7. Uncertainty as to whether photonic tag detectors will be installed on time and operate satisfactorily; uncertainty as to effectiveness of photonic tags.
8. Uncertainty toward theft, tampering, or vandalism of sampling equipment.
9. Uncertainty of successful trapping operations during sudden high flow events, without incurring damage to traps.
Ongoing monitoring and evaluation projects in the Umatilla basin do not include an evaluation of the overall migration success and survival of hatchery-released and naturally-produced salmonids to the lower river. Long-term monitoring is necessary to obtain reliable information on outmigration characteristics, survival, and passage problems for both hatchery and natural salmonids. This information will be used to make management decisions to enhance in-river survival and facility passage at irrigation diversions. Passage problems for juvenile salmonids currently exist at Three Mile Falls Dam; differing operations of West Extension Canal under Phase I pumping affect bypass effectiveness and juvenile passage past the dam. Information on migration rates and timing, overall survival in relation to river conditions and canal operations, and canal bypass collection efficiencies for juvenile salmonids is necessary for decisions on canal operations, water release strategies, and flow enhancement strategies. Information on fish needs for passage, rearing, and survival is vital to further "tweak" the Umatilla Basin Project.
Although smolt-to-adult survival is being assessed through the Umatilla Hatchery Monitoring and Evaluation project, results are broad in scope and long-term in being fully analyzed. Fine-tuning of hatchery practices can be accomplished with basin-specific information on the outmigration of specific rearing and release strategies. Monitoring of natural juvenile salmonids in the lower river is necessary to address critical uncertainties related to natural production monitoring and evaluation and to ascertain life history characteristics in the lower river. Uncertainties related to the success of summer steelhead and fall chinook salmon production groups require a closer in-basin look at survival and migration factors. Degradation of river conditions during summer low flows exacerbate survival problems for subyearling fall chinook salmon. Pathological assessment of hatchery and natural mortalities will further our understanding of fish health in river.
Predation by avian and fish predators may significantly impact the survival success of juvenile salmonids. Information on predators is important to understand the potential for loss of juvenile salmonids at passage facilities and to develop predator deterrence strategies to improve fish survival. Information on health and survival of transported fish is necessary to improve transport practices. Loading procedures and transport conditions may be affecting juvenile fish survival.

The multiple-capture history protocol for estimating reach-specific survival was rejected due to limited personnel to staff a multitude of capture facilities (Burnham et al.1987); lack of PIT tag technology required hands-on marking and detection.
Justification for planning
(N/A) Project in implementation phase.
1. Collection of outmigrating juvenile salmonids through daily, hourly, or periodic monitoring throughout the day of trap catches using a rotary-screw trap during late summer, fall, winter, and spring and the canal bypass facility at West Extension Canal during late spring and early summer. Fish will be identified to species and origin, counted, and examined for marks, clips, condition, and smoltification level. Lengths will be collected on a representative subsample of hatchery fish and all natural fish collected.
2. Estimation of species-specific collection efficiencies using an acrylic paint mark; daily marking and releasing of fish species for species-specific efficiency estimates over wide range of river flows. Holding of fish after marking and prior to release to estimate marking survival. Abundance estimates based on number collected and efficiency estimates with Bootstrap derived variance estimates for 95% confidence intervals.
3. Bi-weekly subsampling of fish at Westland Canal holding pond during trap and transport operations; sampling to back-fill CTUIR sampling. Subsampling of fish from holding pond and transport vehcile whenever fish are transported to evaluate condition and delayed mortality of transported and non-transported fish.
4. Recording of juvenile fish passage and behavior at ThreeMile Dam fish ladder using an underwater video camera at the fish exit gate and a video camera at the fish viewing window.
5. Acquisition of environmental data from USGS and Water Resources records; daily acquisition of secchi disk readings and max-min temperature at collection sites. Documentation of canal facility operations and meteorological data.
6. Daily observation of avian predators at sample sites; documentation of resident fish species and piscivorous fish in collection samples and measurement of lengths.
9. Installation of detectors, and detection of photonically-tagged fish using hand-held detectors at traps and remote detectors at canal and ladder facilities. Downloading of data from remote detectors on regular basis.

SUMMARY OF EXPECTED OUTCOMES
Expected performance of target population or quality change in land area affected
Results of monitoring will be used to better understand the affects of specific hatchery rearing and release strategies, to guide decisions on passage facility and canal operations, flow enhancement strategies, and transport practices, and to augment knowledge of natural production life history characteristics. Results will inform managers of outmigration success within the Umatilla basin of natural and hatchery salmonids. With potential implementation of strategies to improve outmigration and passage, survival of outmigrating target populations should provide an increase in adult returns.
Present utilization and convservation potential of target population or area
Present use of chinook salmon and steelhead populations are for commercial, sport, and tribal fisheries, in the Columbia and Umatilla river basins. Present use contributes more than 6,000 hours of sport fishing recreation annually in the Umatilla basin. The conservation potential is present to reestablish naturally reproducing salmon stocks and to supplement steelhead stocks.
Assumed historic status of utilization and conservation potential
Historic use was major fisheries which supported Indian and non-Indian fisheries (Boyce 1986). Historic numbers of fish are unknown, but are believed to be major contributors to Columbia River fisheries.
Long term expected utilization and conservation potential for target population or habitat
The target populations are expected to significantly contribute to Columbia River doubling goals and the establishment or supplementation of naturally reproducing populations in the Umatilla River. Uses include commercial, sport, and tribal fisheries in the Columbia and Umatilla river basins. Long term goals for adult returns to the mouth of the Umatilla River are: 11,000 natural and 10,000 fall chinook salmon, 1,000 natural and 10,000 hatchery spring chinook salmon, 4,000 natural and 5,670 hatchery steelhead, and an undetermined number of natural and 6,000 hatchery coho salmon.
Contribution toward long-term goal
Products of the project will contribute to: evaluating critical uncertainties about survival potential and migration success of hatchery and natural stocks, leading to restoration and supplementation of salmon and steelhead populations in the Umatilla River; to reestablishment of anadromous fisheries in the Umatilla River; the Columbia River doubling goal; evaluation of new marking technology that will have potential application throughout the Columbia basin.
Indirect biological or environmental changes
Physical products will include the installation of approximately 4 remote photonic tag detectors, archival video images of juvenile fish within ladder sections, and the collection of approximately 400 scale samples and various samples of fish species.
Environmental attributes affected by the project
Information on migration patterns as related to flow may effect a change in flow release strategies.
Changes assumed or expected for affected environmental attributes
Flow enhancement strategies will be fine-tuned toward specific needs for fish migration and provide minimum in-stream flows during all months of the year.
Measure of attribute changes
Assessment of effects on project outcomes of critical uncertainty
Uncertainty of handling effects will be assessed by holding samples of fish for delayed mortality tests.
Information products will include relationship between diversion rate and canal bypass efficiency; fish behavior, impacts at ladder diffusers; fish counts at viewing window; migration timing, rates, magnitude and duration; median capture data; diel movement patterns; fish condition by species through time; pathology of diseased and dead fish; collection efficiencies; migrant abundance estimates; survival indices/estimates; velocity measurements; trends in smoltification through time; length frequency distributions and mean lengths; migration/flow relationships; identification of resident fish species and avian predators; documentation of environmental and hydraulic parameters; collection numbers of salmonid species and brand groups; numbers of photonically marked fish passing through canal bypass or east-bank ladder.
Cordination outcomes of the project include regular coordination of activities with various agencies and entities and coordination of equipment loans and information needs.
Product outcomes should be measured by assessing whether they address objectives specified in the annual contract and whether outcomes contribute to the specified intent of the process.
Provisions to monitor population status or habitat quality
Population status of target stock is specifically monitored by outmigration trapping of juvenile life stages in the lower river. Natural production M&E monitors juvenile population status in upper river reaches and conducts spawning escapement surveys. Adult returns of salmonid stocks are monitored at Three Mile Falls Dam trapping facility. Remote detection capabilities will monitor photonically tagged fish at Three Mile Dam. Coded wire tag recoveries in commercial and sport fisheries provide ocean and river harvest information.
Data analysis and evaluation
Project data will be analyzed and evaluted through descriptive statistics, chi-square goodness of fit and tests of independence, parametric t-tests, analysis of variance and correlation analysis. Trend data will be compared between years.
Information feed back to management decisions
Information from project findings is transferred to management via cooperative meetings, memos, reports (annual, quarterly, monthly), and research reviews.
Critical uncertainties affecting project's outcomes
Resolution of critical uncertainties could be addressed by anticipation of uncertainty events and allowing for a greater degree of preparedness.
Overall project performance could be assessed through the provision of new knowledge to increase understanding of migration dymanics and survival factors; by reduction in fish delay and potential injury at critical ladder areas; by workable recommendations for flow release strategies to stimulate migrational movement; through statistically valid abundance estimates, successful use of photonic tags to monitor fish migrations; and, through workable reccomendations on canal and ladder operations to effectively route fish.
Incorporating new information regarding uncertainties
New information about uncertainties affecting the project will be incorporated into the decision process through coordination meetings and adaptive managment.
Increasing public awareness of F&W activities
The project will assist in increasing public awareness of efforts to enhance wildlife through outreach plans of individual project staff. Such plans include informational signs regarding trapping operations and project goals, school presentations, job shadow and mentoring opportunities, newspaper articles on project activities, regular radio segments, field tours to local students and officials, and cooperative work with landowners.
