LTR - Lower Tucannon River
Status: Active - OperationalGeneral Operational Period: Year Round
Start Date: 10/1/2005 12:00 AM
LTR is a permanent instream PIT tag interrogation site at RKM 2.5 on the Tucannon River. The current configuration installed August 2020 consists of three rows of antennas. The upstream row consists of 2 20-foot HDPE antennas, the middle row consists of 2 20 foot HDPE antennas and 1 10 foot PVC antenna, the bottom row consists of 2 HDPE antennas, installed in flat-plate configuration. Each antenna is powered by a Biomark Multiplexing Reader IS1001-MC master controller. The antennas were built and installed by WDFW. The electrical power at the site is provided by 6 200 watt solar panels. Data currently will be downloaded by Biomark through a satellite modem. No environmental monitors are installed at this time. This site has variously consisted of one or two groups of arrays, about a kilometer apart, located near the mouth of the Tucannon River. From Oct. 2005 until April 2008 the downstream array group consisted of two tandem "log" antenna arrays that spanned the low-water channel above the boat ramp. The upstream array group was located at an abandoned railroad bridge abutment upstream of Hwy 261 on the Tucannon River downstream from Starbuck. The upstream array (A0) operated from Oct. 2005 until January 2009. Its various configurations included both pass-through and pass-over antennas. A single array (C0) with six PVC pipe antennas powered by a QST Qube was re-deployed above the boat ramp in Sept. 2009. Responsibility for site operations transferred from USFWS to WDFW on Jan. 7, 2010. The C0 in-stream array was relocated below the Hwy 261 bridge on Sept. 29, 2010. The Qube was replaced with a Biomark IS1001-MC November 2018.

| 2011 | 1/1/2011 12:00 AM | 1/1/2012 12:00 AM | Site down from February 24-28 and April 3-12. High flows caused various antennas to lose power or have high noise throughout the season - see event logs for details. Three antennas were replaced August 16, but not fully functionaly until August 29. |
| 2010 | 1/7/2010 12:00 AM | 1/1/2011 12:00 AM | Data collected prior to Jan. 7 were lost due to an equipment failure. No data are available between Jan. 19 and Feb. 4 due to a complete loss of power and failure of the lithium battery. No data are available between Feb. 16-18, Apr. 16-21, or May 10-24 due to loss of buffered records. No data available between Sept. 1-20; propane ran out. Detectors were moved upstream near the Hwy 261 bridge on Sept. 29, 2010. No data between Dec. 1-13 due to a TEG malfunction. |
| 2009 | 1/1/2009 12:00 AM | 11/22/2009 11:53 AM | The original A0 MUX array was washed out on Jan. 8, 2009. The downstream antennas in the Tucannon River (identified by transceiver C0) were reinstalled on September 10. These antennae replace the upstream array (transceiver A0) that was blown out. The configuration of the new antenna array is as follows, looking downstream: Beginning on the left hand streambank is C1, C2, and C3 (C3 is approximately mid stream). Slightly downstream (approx. 2 feet) beginning mid stream and going towards the right hand streambank are C4, C5 and C6. There is overlap of C2 and C3 with C4 and C5. Data collected between Nov. 22, 2009 and Jan. 7, 2010 were lost due to an equipment failure. |
| 2008 | 1/1/2008 12:00 AM | 1/1/2009 12:00 AM | On May 22, Steve Anglea (Steve.Anglea@biomark.com) discovered that the downstream antenna at the old railroad bridge (A6) had washed away sometime on May 19, and that the entire downstream pass-over antenna array had been dislodged by a tree. The pass-over system was shut down on May 22. |

| 6/20/2017 1:19:21 PM | General | • Lower Tucannon River (LTR) – – Site visit January 12th. Low amperage coming out of solar panels do to extended snow and overcast. Charged batteries. Low amps antenna 4. Charged batteries again on 1/26&27/2017. February 20th continued flood like river discharge has damaged or destroyed most of the site making any repair problematic at this time. June 19th repairs are ongoing and should be completed this summer. |
