Note: In this first year of detections at the Lower Granite Spillway (GRS) antennas, information and understanding of the detections are developing in real-time. During a non-spill period on 12 February 2020, an adult steelhead was detected in the tailrace by the lower antennas of the system over a period of 50 minutes. DART is actively investigating methods to identify these adult tailrace detections as a separate activity from fish detected passing from forebay to tailrace through the spillway. Currently, these detections are included in the daily fish counts presented in the table.

Note: In this first year of detections at the Lower Granite Spillway (GRS) antennas, information and understanding of the detections are developing in real-time. During a non-spill period on 12 February 2020, an adult steelhead was detected in the tailrace by the lower antennas of the system over a period of 50 minutes. DART is actively investigating methods to identify these adult tailrace detections as a separate activity from fish detected passing from forebay to tailrace through the spillway. Currently, these detections are included in the daily fish counts presented in the table.

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.
