Interrogation Site Metadata

PD4 - Columbia River Steamboat Slgh

Status: Active - Operations Unspecified

Site Type: Instream Remote Detection System | Organization: NOAA Fisheries

General Operational Period: Seasonally
Start Date:

In-river detection system consisting of up to six 8ft x 20 ft antennas in the Columbia River Estuary. The array is located near river km 54, is operated by NOAA Fisheries, and was installed on May 5, 2026, for seasonal monitoring (April - September) targeting detections of migrating juvenile salmonids. The array includes a Biomark IS1001 master controller, with an individual IS1001 reader assigned to each antenna. A solar panel array is affixed to an electronics barge to charge a battery bank of four 12v marine batteries. Remote communication will be provided via a cellular modem. All electronics are contained within two Pelican boxes affixed to a floating barge that is tethered to the downstream side of the dike. Antenna groups are based on orientation relative to the pile dike, with numbering starting with the terminal king piling of the structure.
