Query Notes

1. This is a complex report and may take several minutes to complete.
2. DART PIT Tag Instream Arrays & Subbasin Methods
3. PIT Tag Subbasins Interrogation Sites, Recapture Locations, and Year Ranges Fact Table
4. DART PIT Tag and ESU Metadata & Glossary
5. For Winter runs, select Observation Year for the start year, select "Span Calendar Years" for Date Range Type, and enter Start Date and End Date for Date Range. Date Range years are determined by selections for Observation Year and Date Range Type.
6. If releases are missing from the results, try the query again with Not Strict Basin RKM option checked. DART uses release rkm and site rkm to determine inclusion and exclusion in a selected basin or tributary. For example, with this option checked, releases with River KM of 754.089 and 754.089.001 would "match" for Nason Creek. With strict match, 754.089.001 designates Nason Creek where as 754.089 designates a release on the Wenatchee River. Strict match is the query default.
7. Full detection histories are available from each query type results.
   • For Observation queries, the selections for Year and Date Range apply to the Observation Year and the basin selection is for Observation Basin. Selected Stage will be applied to Observations.
   • For Release queries, the selections for Year and Date Range apply to the Release Year and the basin selection is for Release Basin. Selected Stage will be applied to Observations.
   • For Tag Files queries, the selections for Year and Date Range apply to the Release Year and the basin selection is for Release Basin. Selected Stage will be applied to Observations.
8. Available detection coverage in basins vary widely as instream arrays are installed or no longer maintained in tributaries. Please consult the PIT Tag Subbasins - Interrogation Sites, Recapture Locations, and Year Ranges table for DART detection year ranges at interrogation sites and recapture locations within a basin.
9. For the most complete basin reporting, select the Include Recapture Dataset option. Several basins make use of the recapture dataset to report observations at sites that are not official PTAGIS interrogation sites. The default setting is to include the recapture dataset.

Disclaimer

This is a complex query that aggregates PTAGIS Tagging dataset, PTAGIS Recapture dataset, PTAGIS Interrogation dataset, and the DART Life Stage Filter. DART strives to the best of its ability to correctly categorize the life stage of each fish at each detection into three stages: Adult, Juvenile, and Unknown. However, there will be miscategorized fish. The query bases further analysis on the detection stage of the fish and values in the Tagging dataset, Recapture dataset and Interrogation dataset (length, release date, release/recapture/detection river km, detection date, detection/recapture site). This may lead to misidentification of fish at detection as Kelt, Repeat Spawners, Ghost, Minijack and/or Jack. It is the responsibility of the user to verify the parameter values for any particular individual tag. DART welcomes inquiries into any categorization of a particular tag_id. We appreciate your assistance with the improvement of these analyses.
