Interrogation Site Metadata

Site back up after replacing the batteries that had gone bad at the site.  All antennas tuned and tested prior to leaving site.

Site visited for maintenance and to download buffer when it was discovered that both banks of batteries at the site have gone bad.  Current batteries have been in operation at ACB since September 2018.  Replacement batteries have been ordered and will be installed immediately upon receipt.

Site visited to install a new/replacement ACN node for antenna 04.  Antenna 04 has been inoperable since it was reinstalled into its former position in early July 2023 after breaking free from its anchors during the flood/debris event in late December 2022.  Once the node was installed and connected, antenna 04 was tuned, tested and is now operating normally.

Antenna 01 was disconnected from its node/ACN on 4/28/2023 due to a high flow/debris event in Asotin creek.  Antenna 01 will be reconnected to its node as soon as conditions permit.

Antenna 01 was disconnected from its node/ACN due to high flows and debris.  It will remain disconnected until flows allow for reconnection.

Antenna 01 was reanchored into position on 2/8/2023 and reconnected to its node/ACN on 2/13/2023, now operating normally again.  Antenna 01 had been disconnected and broken free of its anchors since the flood event that began on 12/26/2022.  Antennas 01 and 02 are anchored in position and operating normally.  Antenna 04 is connected and operating at the site but broke free of all but one anchor and is resting up against the south bank.  Antenna 03 was recovered on 2/1/2023 out on the Snake River and appears to still be operable and will be reinstalled asap.

Site visited to further assess damage to array infrastructure after a recent flood event.  Antenna 01 is present at the site but broken free from most its anchors and will need to be reset/reanchored.  An attempt was made to plug antenna 01 back into its node and reestablish a connection, however it would not connect to the MC so there is a good chance that the node/ACN for antenna 01 will need to be replaced.  Antenna 02 is present at the site, connected and still operating, however it experienced severe scouring around its anchors and will need to be reanchored.  Antenna 03 is absent from the site, broken away from all of its anchors.  A recovery mission to try and locate antenna 03 will occur soon.  The node for antenna 03 is present at the site and appears to be undamaged but its working condition remains unknown.  Antenna 04 is present at the site, connected to its node and operating normally, however, it had been broken free from all but one of its anchors by large woody debris and swung up against the south bank.  Antenna 04 will need to be reanchored back into postition.

Site visited 12/30/2022 to download buffer and assess damage to the site from a flood event that began 12/26/2022.  Antenna 01 (upstream, river left) had been disconnected from its node but appeared to remain in its anchored location.  Antenna 03 (downstream, river left) was not operating at the time of the flood event as it needs a replacement node, and it was unclear whether antenna 03 remained in its anchored position upon this visit.  Antennas 02 and 04 (up and downstream, river right) remained in their anchored positions and connected to their respective nodes, operating normally.  The site will be revisited the week of 1/1/2023 to further assess damage once stream flows have dropped to an appropriate level.

Site visited to attempt to reconnect antennas 01 and 03 as flows in Asotin Creek have subsided enough to allow for an attempt.  Both antennas were plugged back into their respective nodes.  Antenna 01 was reconnected without issue and tuned.  Antenna 03 would not reconnect so further troubleshooting will happen as time allows to determine whether the issue is with the node or the antenna.  Antenna 01 was non functional  between June 8 and this visit on June 30.  Antennas 02 and 04 continue to operate normally.

Antennas 01 and 03 became disconnected from their nodes during the early morning of June 8, 2022 due to a flood event occurring in Asotin creek.  Antennas 01 and 03 will remain disconnected until stream flows decrease enough to reconnect them.  Antennas 02 and 04 continue to operate normally.

Site visited to reconnect antennas 01 and 03 as flows have subsided somewhat in Asotin Creek.  Both antennas 01 and 03 were reconnected without issue and tuned prior to leaving site.  ACB now fully operational once again.  Antennas 01 and 03 were non operational between May 7 2022 and May 25, 2022.

Site visited to assess damage after a recent high water/high debris event that began the evening of May 6.  Antennas 1 and 3 were disconnected from their nodes during the early morning hours of May 7.  All antennas appear to still be anchored in place.  Further damage assessment will occur once flows recede and visibility improves.  Antennas 2 and 4 continue to operate normally.
