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

Data Courtesy of Pacific States Marine Fisheries Commission

Select Reach, Year

Select Release Group, Species-Run, Spill Period

Juveniles Released At/Above Lower Granite

Spring/Summer Chinook with Unknown-run tagged at LWG in April and May

Spring Spill, April 3 - June 20 (data for upper project displayed through June 30)

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

Optional: Set End Date

Use End Date No Yes

End Date mm/dd

Note: Click "Yes" radio button to activate "Use End Date" option. The purpose is to examine results for a particular past date. Activating "Use End 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

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. Changed critical "average" travel time for double reach, LMN-LWG, to calendar day 4 after departure date.
Documentation and Methods to be written.
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.
