DART PIT Tag Adult Ladders -- Reach Distribution and Delay -- In Development

Data Courtesy of Pacific States Marine Fisheries Commission

We plan to expand analysis to mainstem Columbia River reaches for the spring spill period in 2019.

Select Reach, Year

Note: Year in brackets following the reach indicates earliest year available.

Select Release Group, Species-Run, Spill Period


Note: Fish detected as Juveniles or Minijacks are excluded from analysis. Jacks are included in both PIT Tag and Adult Visual Count datasets.

Set Summary


Optional: Set Past Date

mm/dd

Note: Click "Yes" radio button to activate "Use Past Date" option. The purpose of this option is to examine results for a particular past date (a.k.a. moving back in time). Activating "Use Past 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.

Methods and Query Notes

  1. 2018-June-18. Implemented new plot for Daily YTD Conversion Rate for Adult PIT Tags and Adult Visual Counts.
  2. 2018-May-17. Implemented updates for handling of running 3 day cumulative arrival percent. Changed critical "average" travel time for double reach, LMN-LWG, to calendar day 4 after departure date.
  3. Documentation and Methods to be written.
  4. 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.
