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)
PIT Tag Specification Document
PTAGIS Interrogation Site Metadata
