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.
