Project development phase Implementation
Related projects include: Fish Passage Center (9403300), Smolt Monitoring by Non-Federal Entities (8712700); Smolt Monitioring by Federal Entities (8401400), PIT Tagging Wild Chinook (9102800), Columbia Basin PIT-Tag Information System (9008000), Networked-Based WWW Information Infrastructure (9207104), In-season Operations Technical Management Team (TMT) Support (9601600), and Second-Tier Database Support for Technical Management Team (TMT) (9601900).
This BPA project focuses on developing statistical methods and software tools for the systematic prediction of salmonid smolt outmigration status and trends, as well as forecasts of the cumulative passage of sensitive ESA stocks and other populations. The Smolt Monitoring Program projects, the Fish Passage Center and the PIT-Tag Information System (PTAGIS) primary-tier database centers, and the second-tier database support center DART project 9601900 provide the data used to make the real-time in-season predictions. The predictions from these tools are provided interactively to the fisheries community, including NMFS TMT via the World Wide Web to assist management of flow and spill augmentation to maximize benefits to smolt outmigration. The statistical tools are made available to all parties wishing to enhance monitoring and evaluation capabilities of their agency and of the fisheries community.
Project was initiated in response to ESA listings and the need for synthesis of biological information and development of new methodologies for application in river management to improve the protection of T&E stocks. Focuses on analysis and synthesis of existing mainstem passage data collected by the Smolt Monitoring Program and other mainstem research on wild and hatchery-reared salmonid smolts, with emphasis on wild threatened or endangered stocks and development of new approaches to assess their status. Gained knowledge and understanding will be applied to improve the effectiveness of hydrosystem operations to improve the protection of these sensitive populations through the FCRPS.
This project has evaluated the information content of historical tagging studies on Snake River salmonids. Information is being used to help design and direct future research efforts and determine reliability of existing information. Historical data has and continues to be explored to reveal possible relationships between river condition
s and salmonid survival, outmigration timing, speed, and outmigration success. Specific accomplishments by year include:
1991: Report on historical brand release data for the Snake River.
1992: Report on a "strawman" smolt monitoring design for Snake/Columbia River systems.
1993: Report on adult PIT-tag returns.
1994: Development and testing of REALTIME PIT Forecaster statistical software using pattern recognition and neuronets to predict the outmigration timing of spring runs of wild Snake River spring/summer chinook at Lower Granite Dam.
1995: Refinement of REALTIME PIT Forecaster statistical software and initial testing of REALTIME Passage Index Forecaster statistical software to predict outmigration timing of summer/fall runs of juvenile fall chinook at Lower Granite Dam. Report on transportation benefit analysis methods. Report on Priest Rapids hatchery returns versus river conditions.
1996: The project is narrowing its focus to prepare for and participate in inseason predictions of smolt outmigration timing at Snake and Columbia River Dams. This effort is expanding predictive capabilities to 4 Snake River dam sites in 1996 and to more sites in 1997, including Mid-Columbia and mainstem Columbia River Dams.
Biological results achieved
Tens of millions of coded-wire-tagged (CWT) and hundreds of thousands of passive-integrated-transponder-tagged (PIT-tagged) salmonid smolt are released into the Snake/Columbia River system annually. The data derived from these tagged fish provide needed information for postseason evaluation of outmigration success and inseason management of flow and spill. This project has provided needed analyses of smolt travel time, survival, and outmigration timing used in mainstem management and protection of endangered stocks of salmon.
Specific biological results of this project include:
1. Evaluation of travel time information contained in freeze-brand data.
2. Evaluation of the annual pattern of adult salmon returns to the upper Snake River from PIT-tag data.
3. Recommendations for complete life cycle survival studies using combined PIT/CWT releases.
4. Evaluation of the relationship between Priest Rapids hatchery adults returns and river conditions.
5. Evaluation of effects of river pulsing on smolt travel times.
6. Evaluation of the benefits of smolt transportation at Priest Rapids and McNary Dams.
Together, these biological results are helping to evaluate past management decisions and improve future efforts to enhance wild salmonid stocks. Finally, since 1994, the project has been providing run timing predictions of endangered wild salmonid stocks in the Snake River and making these predictions publicly available to the fisheries community.

This BPA project is providing the statistical, computer, and telecommunications needs to analyze and disseminate information on the status and timing of spring and summer outmigrations in support of the adaptive management framework.. To this end, Program REALTIME uses passage indices and PIT-tag detections to make daily predictions of the "percent run to date" and "date to specified percentiles" of wild endangered salmonid stocks in the Snake River and posts results daily on the World Wide Web for the fisheries community. These predictions help focus spill and flow augmentation to maximally benefit smolt outmigration.
Specific measureable objectives
1996: Expand development of real-time outmigration prediction to include all Lower Snake River hydroprojects as well as facilitate incorporation of Mid-Columbia predictions. Expand internet access to cover historical run timing and flow data at all major hydroprojects.
1997: Investigate extending outmigrating timing predictions to Lower Columbia hydroprojects.
1998: Adapt REALTIME data analyses of outmigration timing to the changing needs of river managers.
The project's analyses of historical tagging data routinely tests hypotheses and looks for correlations between tag returns and environmental and human-related effects. Specific hypotheses include:
1. Flow-travel time relationships of outmigrating smolt
2. Flow-survival relationships of outmigrating smolt
3. Travel time-river pulsing relationships of outmigrating smolt
4. Temperature, turbidity, hatchery release numbers on in-river smolt survival
5. Low-adult return rate relationships.
With the increased focus on outmigration predictions, the project is testing basic hypotheses concerning outmigration timing and dynamics, that are tested annually when actual run timing is compared to daily predictions at the end of the season.
Underlying assumptions or critical constraints
1. Smolt Monitoring Program continues to operate and collect in-season and time-series data on the migrational characteristics of Columbia and Snake River populations of salmon and steelhead.
2. FPC and PTAGIS database centers continue to provide passage index and PIT-tag detection information in-season.
3. Marking of juvenile fish continues.
4. Support for adaptive management framework continues.
Historical databases on tag detections (brands, PIT-tag), tag recoveries (CWT), and ambient river conditions (flows, temperatures, spill volumes, etc.) are analyzed using SUN workstations and a variety of statistical methods (e.g., generalized linear models, nonlinear regression, mark-recapture theory). Predictions of outmigration timing
are based on advanced mathematical/statistical techniques including fuzzy logic, generalized models, and bootstrap/jackknife procedures. Output of outmigration timing predictions posted on the World Wide Web.
Brief schedule of activities
1997: Investigate extending outmigrating timing predictions to Lower Columbia hydroprojects.
1998: Adapt REALTIME data analyses of outmigration timing to include other site locations such as Mid-Columbia stocks and dams and to continue to meet the changing needs of river managers.
Prediction of where the wild stocks of salmonid smolt are in their outmigration facilitates management decisions on the timing and placement of water budget releases and spill to protect endangered stocks.
Project strives to use statistical methods to unravel the uncertainties of tagging data and outmigration dynamics.
Summary of expected outcome
The project will provide daily predictions of outmigration timing at Lower Granite, Little Goose, Lower Monumental, Ice Harbor, and Wanapum Dams and associated confidence intervals during spring and summer 1996 and subsequent years. Subsequent years will proceed with predictions in the Mid-Columbia and Lower Columbia.
