The results of this analysis will be used to inform Reclamation’s consultation with NOAA Fisheries. Picture from ODFW

(2006) 1.Use a quantitative framework akin to life- cycle modeling 2.Express quantitative findings in terms of VSP criteria 3.Evaluate a range of circumstances that represent uncertainty 4.Identify and use explicit measures of uncertainty

4. www.fishsciences.net The Cal-Fed reviewers suggest a “life-cycle” approach. …a biological conceptual framework is necessary to provide a context for integrating diverse types of scientific information into overall assessments of viability and risk at the population and ESU level. 1. Use a quantitative framework akin to life-cycle modeling Life-stage-level effects Population-level effects Predicting how alterations to fish habitat affects populations

5. www.fishsciences.net …consideration of basic VSP principals will help form an explicit conceptual framework for a BiOp. …even in data-poor situations VSP provides a useful organizing framework for considering risks to salmon populations and ESUs, and clear references to this framework in future Biological Opinions will enhance their transparency as well as their scientific credibility. … actions proposed in a BiOp should be evaluated with respect to their effects on the four VSP viability criteria 2. Express quantitative findings in terms of VSP criteria Abundance Productivity Spatial Structure Diversity

6. www.fishsciences.net The Cal-Fed reviewers suggest developing a series of scenarios that represent a range of possible future climates and water demand situations. The BiOp should have evaluated whether the populations will be able to bear the increased mortality under the full range of ocean conditions, which will include periods of poor survival as well as good periods. The Cal-Fed reviewers urge that the effects of hatchery fish be analyzed concurrently with the other project impacts 3. Evaluate a range of circumstances that represent uncertainty Climate Change Ocean Conditions Hatchery Fish

7. www.fishsciences.net Addressing reviewer’s concerns about biological uncertainty will require an iterative process of 1) collecting interdisciplinary scientific observations, 2) building and re-building models of the populations within their environments, and 3) running the models in data assimilation mode to advise the content and design of data collection programs, hence back to step 1… The process of data assimilation not only tests the logic and parameters of the model against reality, but it can also be used to identify which variables are most critical, and the minimum frequency or density of observations necessary to estimate a given parameter. 4. Identify and use explicit measures of uncertainty Statistical uncertainty Biological uncertainty

Request data for the proportion of flow sampled to couple with the catch data, so we that we can adjust the estimates of fish passage accordingly. Explore both linear and hockey-stick flow scalars within the model.
