Interrogation Site Metadata

HRM - Hood River Mouth

Status:   Active - Non-Operational
Site Type: Instream Remote Detection System  |  Organization: Confed. Tribes of the Warm Springs Reser.
General Operational Period: Year Round
Start Date: 1/9/2012 12:00 AM

An instream interrogation system consisting of 2 antenna arrays located at the mouth of the Hood River. The antennas are against the west side jetty just inside the bar where the Hood River meets the Columbia River. The upstream array is comprised of five 20 foot antennas covering a total of 100 feet from shore. The downstream array is comprised of two 20 foot antennas that extend 40 feet from shore. The antenna arrays cover approximately 3/4 the stream width at low water conditions and a half of the stream at bank full. The transceiver is a IS1001-MTS and power is provided by solar panels charging a battery bank. Interrogation data is submitted several times a week via cellular modem.

Configuration metadata includes details about the equipment used at the site to detect and record PIT tags. A new configuration sequence record is created when equipment is added or removed from the site and the period of time it was active. A configuration sequence without an End Date is currently active.

Event Log Summary

Event Date Event Type Comments
1/13/2021 12:00:00 PM General Antennas #4 and #7 apparently damaged during high water and lost tune. Removed from firing order.
6/12/2019 1:20:00 PM General Antenna #5 was replaced with a better performing antenna. Erratic tuning on Antenna #7 was addressed with a node replacement.
2/9/2019 8:45:00 AM SiteDown Site down during snowpocalypse from February 9th to 13th.
10/24/2018 10:30:00 AM General Antenna #5 and its node was replaced and successfully tuned returning it to function.
2/27/2018 12:00:00 PM General Antennas #4 and #5 were not functioning consistently after a high flow event in early December 2017. Eventually connection was lost to both antennas. On February 27 the node for antenna 4 was replaced restoring the function of that antenna. During the site visit it was confirmed antenna 5 was damaged and will need to be replaced during low water.
4/20/2017 11:00:00 AM SiteUp Failed node on antenna #1 replaced and connection to upstream array (antennas 1-5) restored and antennas resumed normal function.
4/2/2017 11:00:00 AM SiteDown Connection lost with the upstream array (antennas 1-5).
12/31/2016 8:00:00 AM General Periodic outages during snowstorms throughout December 2016 which buried solar panels.
6/10/2016 11:00:00 AM General Nodes replaced on antennas #6 and #7 bringing them back into service.
3/8/2016 1:00:00 PM SiteUp Failed component replaced and site back online. All antennas in upstream array (1-5) functioning.
2/26/2016 12:00:00 PM SiteDown Site down due to component failure.
12/9/2015 12:00:00 PM General Flood event took antennas #1,#4, and #5 out of service. Antennas #4 and #5 replaced on January 11-12, 2016.
12/3/2015 12:00:00 PM General Took antennas #6 and #7 out of service for node repairs.
10/15/2015 9:00:00 AM General Repair and reconfiguration of the antennas occurred on 10/15 and 16. There are now 7 total antennas, 5 on the upstream array and 2 on the downstream array.
7/21/2015 9:30:00 AM General Antenna #6 went out of service
6/5/2015 1:00:00 PM General Repairs and reconfiguration of antennas and nodes occurred from June 3-5. All three antennas and ACN nodes on the upstream array were replaced (antennas 1-3). An antenna was added to the downstream array (antenna 6).
4/15/2015 1:00:00 AM General An antenna node shorted out taking the upstream array out of service on April 15th (antennas 1-3). Another node was spliced in on May 11th which returned antenna 1 to service but antennas 2 and 3 remained out of service.
10/27/2014 11:30:00 AM SiteUp Site activated again after installation of MTS receiver system and new antennas.
9/30/2014 11:48:00 AM SiteDown Site shut down for installation of new antennas and transceiver system.
2/12/2014 11:07:20 AM General Snow storm from February 8-10, 2014 buried the site's solar array which resulted in power loss. Site was dug out, batteries swapped out, and transceiver reactivated the morning of February 11.
1/22/2014 8:50:12 AM General Site in operation in same configuration entire year of 2013 with only a few brief outages.
1/1/2014 12:00:00 AM General Site in operation until September 30 then shut down until October 27 while new antennas and electronics where installed. Site was operational through the rest of the year in the new configuration.
