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.
Additional Information:
- PIT Tag Release Sites - report includes Site Code, Site Name, River KM, and Hydrounit
- PIT Tag "Standard" Species, Run, Rear Type Combinations (as reported by PSMFC)
- 2009 PIT Tag Specification Document
- PTAGIS Interrogation Site Metadata
