Notes:

  1. Brood Year 2022 is incomplete. Data presented in Migration Timing Characteristics table is data through today's date.
  2. Data Courtesy of USFWS, Lodi
  3. Date Calculations:
    1. Query database for sampling/passage estimates for requested number of years, species, run, and location.
    2. Based on brood year assignment at Red Bluff, regroup calendar year based data into brood year based data for Chinook.
      • Winter, July-June
      • Spring, October-September
      • Fall, December-November
      • LateFall, April-March
    3. Based on query results, calculate total number of fish for each brood year (reported as "Run Size" in table).
    4. Based on query results, calculate cumulative number of fish by day in the year.
    5. Based on query results, calculate the Day of Year when fish passage % is equal to or greater than the target percent, e.g., 5% passage. Passage % for a day = cumulative number of fish for day / total fish in year.
    6. For each individual year target passage percent, first date, and last date results: convert Day of Year to Calendar Date for given year, taking into consideration leap year. Report calendar date in table.
    7. For each individual year middle run duration: 80% duration = 1 + (90% Day of Year - 10% Day of Year), 50% duration = 1 + (75% Day of Year - 25% Day of Year), 90% duration = 1 + (95% Day of Year - 5% Day of Year). Report days in table.
    8. For each target passage percent, first date, and last date: calculate average Day of Year for that passage target percent from each individual year Day of Year values. Convert result into integer. Treat integer as Day of Year and convert into Calendar Date for a non-leap year. Report as Average.
    9. For each target passage percent, first date, and last date: calculate median Day of Year for that passage target percent from individual Day of Year values. Convert median Day of Year into Calendar Date for a non-leap year. Report as Median.
    10. Individual year calendar date values reported in table honor leap year. Calculated calendar date values (Average and Median) treat results as non-leap year dates.
