Status:   Active - Operations Unspecified
Site Type: Instream Remote Detection System  |  Organization: U.S. Geological Survey
General Operational Period: Year Round
Start Date: 9/21/2007 12:00 AM

The Trout Creek interrogation system is located at river km 2 on Trout Creek, in the Wind River (WA.) Basin above Hemlock Lake. The site was originally installed and maintained by USGS and located at river km 4; operational responsibilities were transferred to WDFW in December, 2009.

Event Log Summary

Event Date Event Type Comments
5/19/2021 2:37:57 PM General On 5/5 or 5/6 TRC briefly lost power and settings to the MUX were also lost. This resulted in incorrect dates and loss of antenna tune through 5/18 at about 12:00. Fish were detected and dates were adjusted in the data. Ian
5/7/2021 3:09:09 PM General At around 10 am on April 21, 2021, antenna 6 suffered at failure at the bulkhead penetrator. It will need to be replaced. Ian
2/5/2021 3:49:33 PM General A bad battery in one bank caused some intermittent operation from about 1 Feb to 5 Feb 2021. The shed tag that was in the A1 field has either washed out or broken. It is not being read anymore. Ian
1/28/2021 11:11:01 AM General 3DD.007794211E is a shed tag that washed into the Antenna 1 field during the high water on Jan 12/13. We will attempt to dislodge or destroy it once the water drops. Ian
2/28/2020 10:36:45 AM General Antenna 1 at TRC was running very noisy from around 20 October 2019 to late December when we took it out of sequence. We replaced it on 27 February 2020. Ian
10/30/2019 10:05:20 AM General On 8 October 2019 we replaced antenna 2, which had been down due to a compromised cable. We also put a new antenna in the number 1 position. The new number 1 antenna is running a bit noisy and we are trying to troubleshoot that and get it less so. Ian
7/26/2019 11:47:04 AM General TRC lost power due to a bad battery bank from 12 July 2019 at about 15:30 to 26 July 2019 at about 10:30. Ian
4/26/2019 10:15:25 AM General TRC was down due to power loss on 4/25/2019 from about 0500 to 1530. Ian
3/1/2019 3:19:10 PM General TRC lost power and data collection from 03:30 on 2/27/2019 to 10:30 on 3/1/2019. Ian
4/4/2018 3:51:49 PM General TRC lost power due to a malfunctioning switcher relay on 31 March 2018 at about 2200. Power was restored on 2 April at 16:00. Ian
4/7/2017 4:58:27 PM General TRC lost power from 31 March 2017 to 7 April 2017. Ian
1/23/2017 2:45:23 PM General Due to an ice storm, TRC lost data collection from about 1500 on 20 Jan 2017 to about 1700 on 21 Jan 2017. Ian
11/3/2016 1:18:17 PM General Power was lost at TRC from 20 Oct 2016 at 07:45 to 25 Oct 2016 at 15:30. The breaker at the meter box had tripped, reason unknown. No data during this period. Ian
12/9/2015 4:45:54 PM General At about 2100 on 12/8/2015 contact with Antenna 1 at TRC was lost. Major flood, unknown if pulled cable or damaged antenna. Ian
12/8/2015 4:11:39 PM General At about 1500hrs on 12/7/15, contact was lost with Antenna 2. Will have to wait for lower water to assess. Hopefully just a pulled cable. Ian
11/24/2015 5:08:02 PM General A problem was occuring with one of the switched relays ( we think) and since about Nov 5 2015 we have only been monitoring half time. We replaced the relays on Nov 24 2015. Will be back to site soon to make sure it is monitoring full time. Ian
11/16/2015 11:48:55 AM General TRC lost data from 2 Nov 2015 at 13:17 to 5 Nov 2015 at 12:00 due to failed lithium battery. Ian
8/28/2014 2:25:57 PM General On 28 August 2014 at about 12:00, Antenna 3 at TRC was replaced with a new antenna. The older one had experienced and amperage drop beginning around October 2013 and had lost reading efficiency. Ian
7/21/2014 2:59:25 PM General The power breaker at TRC was tripped sometime after 11am on July 15. The site was reset at 12:30pm on July 21 2014, but there is no data recorded for the interval between. Ian
5/27/2014 10:30:00 AM General The cable to antenna 6 was replaced on 5/27/2014 at about 10:30 am. Antenna 6 is now back online. Ian
4/28/2014 1:03:00 PM General Antenna 6 at TRC lost power at about 10pm on 28 April 2014. Likely a worn cable. Will check out as soon as the water drops. For now the antenna is out of the sequence. Ian
