Winter-Run Chinook Salmon Recovery Scenarios: Coupled Model Analysis for Sacramento River

A 26-year simulation period (1995–2020) is used to evaluate recovery strategies for endangered Sacramento River winter-run Chinook salmon. The study couples water-planning, hydrodynamic, habitat capacity, and survival models within a life cycle model to assess management actions. The supplementary PDF file, authored by Ann-Marie K. Osterback and licensed under CC-BY-4.0, presents the model and results.

Use Cases

• Evaluating the synergistic effects of combined habitat, flow, and harvest management actions based on the coupled model framework described.
• Calibrating life stage-specific survival models for salmonids based on the Winter-run Chinook salmon life cycle model (WRLCM) methodology.
• Benchmarking population recovery projections for endangered species based on the 26-year simulation of historical and future scenarios.

Strengths

• Model integrates multiple domains: water-planning, hydrodynamics, habitat capacity, and life stage-specific survival.
• Scenarios evaluated include a 26-year simulation period (1995–2020) for historical context.
• Results indicate scenarios with multiple actions could increase population size by over 7 times the historical baseline.

Limitations

• The primary data file is a 2.4 MB PDF; underlying model data, columns, and row counts are unavailable.
• Column-level documentation is absent; field semantics must be inferred after download from the PDF text.
• Data may reflect geographic and temporal bias inherent to the Sacramento River case study.
