TCM - Tryon Creek Mouth

Status: Decommissioned

Site Type: Instream Remote Detection System | Organization: U.S. Fish and Wildlife Service

General Operational Period: Year Round
Start Date: 1/1/2014 12:00 AM
End Date: 9/29/2019 12:00 AM

TCM is an in-stream detection system consisting of four PIT arrays about 25 meters apart located near the mouth of Tryon Creek in Lake Oswego. Each array consists of one antenna that spans the creek width during normal flows. All arrays are oriented as pass through antennas except for F2 which is a pass over. Site is no longer active.

Configuration

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
9/16/2019 2:38:00 PM	General	Antennas #1 and #2 ran up until 09/29/2019 when study ended and the site was decommissioned. All data were uploaded and all down times accounted for.
1/1/2019 2:37:00 PM	General	All data and downtime accounted for in 2018.
11/24/2018 2:26:00 PM	General	Antenna # 3 no longer operational. Running only antennas #1 and #2 moving forward
4/4/2018 2:24:00 PM	General	Antenna # 4 no longer operational. Site was running with antennas 1, 2, and 3 moving forward.
1/1/2018 8:02:00 AM	General	All data have been uploaded and downtime has been accounted for the TCM site in 2017.
8/3/2017 8:02:00 AM	General	Antenna # 1 not functioning from 01/30/17 to 08/03/17 due to cable "pig tail" severed during high flow event . Willamette backwater rendered this unfixable till summertime.
1/1/2017 1:01:00 PM	General	All data have been uploaded and all downtimes have been documented for the year 2016.
10/27/2016 1:01:00 PM	General	Antenna # 3 was not in operation from 10/14/2016 to 10/27/2016 (cable was severed after a high flow event).
2/22/2016 1:01:00 PM	General	On 01/01/2016 the only functioning antenna at the mouth of Tryon Creek was antenna #2 (A2) (passover). On 02/02/2016 replacements for A1 and A3 were installed. On 02/22/2016 a replacement for A4 was installed, completing the Tryon PIT site.
12/31/2015 1:28:00 PM	General	All data were uploaded and all down times are accounted for.
1/6/2015 1:18:00 PM	General	Data were lost from 12/30/2014 to 01/06/2015 14:34:49 due to unique not being turned on (resulting in the buffer writing over data).
12/31/2014 7:44:00 AM	General	All data were uploaded. All down times were accounted for.
12/31/2014 7:38:00 AM	General	No data are available for 12/31/2014 and the latter half of 12/30/2014 due to unique delay not being turned on and the buffer filling up.
10/6/2014 4:15:43 PM	General	Registered new interrogation site TCM in PTAGIS.
9/10/2014 7:38:00 AM	General	Replaced Antenna #2 09/10/2014. Both antennas are reading excellent now, all the way through with less than 5% noise.
8/21/2014 7:38:00 AM	General	Due to low detectability and high noise, Antenna #1 was replaced. It is now reading 12 mm tags completely through and noise problems have been eliminated.
2/25/2014 7:38:00 AM	General	Antenna 1 was unplugged and not operating due to a high flow event, from 02/14/2014 to 02/25/2014.
2/11/2014 7:44:00 AM	General	Antennas have been reading intermittently and poorly due to power, cable length and noise issues. As of 02/11/2014 after resolving some of these issues, both antennas are operational.
