DART PIT Tag Adult Reach Distribution and Delay

Data Courtesy of Pacific States Marine Fisheries Commission

Select Year, Release Group

Selection for Release Group controls options available for Reach and Period.
Release Group:
  • "Sp/Su Chinook juveniles released at/above Lower Granite" includes Unknown-run tagged at LWG in April and May in same year as release
  • "Fall Chinook juveniles released at/above Lower Granite" includes Unknown-run tagged at LWG after June in same year as release and Unknown-run tagged by coord_id "WPC"

Select Reach, Date Period

Year in brackets following the Reach indicates earliest analysis year available.

Set Departure Event Calculations

  • Single Departure Event per TagID: On reascent and departure, the TagID is removed from previous departure date cohort and daily calculations are adjusted. That is, each TagID has only one departure event per season.
  • Daily Cohort: Original logic designed to mimic visual adult passage count dataset. Each ascent and departure tracked per departure date. No adjustments made to daily cohort departure events for reascent events. That is, TagID departure events may not be unique within a day or a season.

Set Summary

Optional: Set Historical Date

mm/dd
Note: Click "Yes" radio button to activate "Use Historical Date" option. The purpose of this option is to examine results for a particular historical date (a.k.a. moving back in time). Activating "Use Historical Date" option will cut off all input data at that date. This option does not expand the range of analyzed data outside of designated spill period.

Query Notes
  • Fish detected as Juveniles or Minijacks are excluded from analysis. Jacks are included in both PIT Tag and Adult Visual Count datasets.
  • DART PIT Tag Adult Reach Distribution and Delay Overview, including methods, glossary, and historical reach statistics.
  • DART PIT Tag and ESU Metadata & Glossary
  • Updates
    • 2024-May-18: Added option for Single Departure Event per TagID for Departure Event Calculations. On reascent and departure, the TagID is removed from previous departure date cohort and daily calculations are adjusted. That is, each TagID has only one departure event per season.
    • 2019-May-02: Glossary and plot descriptions added to results. More detailed documentation and methods are in progress. Removed full flow bypass detections from Ice Harbor analysis for consistency with other adult ladders processing and handling.
    • 2019-April-05: Implemented analysis for spring spill period in mainstem reaches. The detection system went live at John Day fishway ladders in 2018, as a result, there is only 1 year of detection data to date. In 2018, harmonic mean travel times were slower than average for all reaches except LGS-LWG.
    • 2019-March-29: Results may now be printed. Issue blocking the ability to print has been addressed.
    • 2018-June-18: Implemented new plot for Daily YTD Conversion Rate for Adult PIT Tags and Adult Visual Counts.
    • 2018-May-17: Implemented updates for handling of running 3 day cumulative arrival percent.
    • Some dates and populations restricted due to detection issues at Little Goose (GOA) adult ladder, 6/18-6/20, 2015. PTAGIS site metadata and event log: GOA.
