Notes

  1. Detection Probability at a Given Project for a Specific Year = r / (r + z)
    where:
    r is the total number of fish recaptured (pit tag detected) within a specific year from a given release, R, at a given project, e.g., McNary, and at any location upstream of the project after the recapture at the given project
    z is number of recaptured fish within a specific year at any location upstream of the given project from a given release, R, not recaptured at the given project
    R is virtual release of fish recaptured at Bonneville Dam Adult Fishways within a specific year meeting the release basin, species, run and rear type criteria.
  2. Standard Error is calculated using the Manly-Parr estimate of detection probability
    SÊ(p̂) = rz / (r+z)3
