Methods and Query Notes

  1. 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.
  2. 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.
  3. 2019-March-29: Results may now be printed. Issue blocking the ability to print has been addressed.
  4. 2018-June-18: Implemented new plot for Daily YTD Conversion Rate for Adult PIT Tags and Adult Visual Counts.
  5. 2018-May-17: Implemented updates for handling of running 3 day cumulative arrival percent.
  6. 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.

Notes on the DART PIT TAG Dataset

On a daily basis, we upload a daily file from PTAGIS, the primary source, into the Columbia River DART PIT TAG dataset. The Columbia River DART PIT TAG dataset does not include orphan tags (tags that have been detected but are not yet associated with a particular release). On a weekly basis, we synchronize the Columbia River DART PIT TAG dataset with year-to-date data from PTAGIS.

Additional Information:

Please refer to the PIT Tag and ESU Metadata & Glossary for more information.
