The WW2 PIT interrogation site is located on the South Fork Walla Walla River approximately 21 kilometers upstream from the confluence with the North Fork Walla Walla River. The site consists of two pass over HDPE antennas that overlap to cover the full wetted width of the river immediately upstream from the Bear Creek confluence. A IS1001 Master Controller and two IS1001 nodes are powered by a thermoelectric generator. Site is no longer active.

| 2005 | 1/1/2005 12:00 AM | 1/1/2006 12:00 AM | The site was down from 9/1/05 at 14:23 to 11/18/05 at 13:42. Propane could not be refilled because of site inaccessibility as result of trail closures due to a forest fire. |
| 2004 | 1/1/2004 12:00 AM | 1/1/2005 12:00 AM | Interrogation was interrupted between 1/22/04 14:00 and 1/25/04 16:00 for computer repairs. No data are available between 2/09/04 20:00 and 2/12/04 18:07. No data are available between 3/23/04 12:00 and 3/25/04 17:43.

| Event Date | Event Type | Comments |
|---|---|---|
| 1/1/2021 2:23:00 PM | General | Due to a flooding event that occurred in early February 2020, transceiver and other equipment were washed away and never recovered. There are no current plans to reestablish this site. All available data are uploaded unless a transceiver is recovered and more data can be extracted. |
| 12/31/2019 12:37:00 PM | General | Not all data have been uploaded from 2019 yet. Will have to wait for weather and/or schedule until site visit. |
| 1/1/2019 1:28:00 PM | General | Due to lack of government funding and winter weather, not all 2018 are submitted at this time. All current data will be uploaded after next site visit. |
| 12/18/2018 1:28:00 PM | General | Site visit with mechanic to troubleshoot thermoelectric generator. The generator was properly tuned and powering the site properly when we departed. |
| 10/24/2018 1:28:00 PM | General | Site visit occurred on 10/24/2018. Identified that transceiver had been switching back and forth. Tried to fix power source and failed. Site essentially down till next visit. |
| 7/17/2018 1:28:00 PM | General | Site was up and running from 06/25/18 to 07/17/18. Unfortunately on 07/17/18 the transceiver once again started jumping between scan and standby mode. Site continued to run in this poor state till 10/01/18 when site went down. |
| 4/5/2018 1:28:00 PM | General | Site visit 04/05/18 occurred and transceiver was turned back on again. Site ran intermittently until shutting off again on 04/24/2018. |
| 1/25/2018 1:28:00 PM | General | Looking back at 2017 data it appears that the transceiver started alternating between scan and standby mode on 11/20/17 until eventually shutting off on 11/21/17. The Transceiver was turned back on 01/25/18, but the problem persisted and only ran for a few hours. |
| 12/31/2017 11:00:00 PM | General | WW217365.ALL has all remaining 2017 data. After the submission of this file, all data for 2017 will be accounted for. All down time has been submitted and accounted for 2017. |
