LWE - Lower Wenatchee River

Status:   Active - Operational
Site Type: Instream Remote Detection System  |  Organization: Washington Dept. of Fish and Wildlife
General Operational Period: Year Round
Start Date: 12/7/2010 3:45 PM

LWE is a permanent instream PIT tag interrogation site at RKM 2.77 on the Wenatchee River. The site consists of two rows of antennas, with each row nearly spanning the wetted width of the channel during base flows. Each row consists of six 20-foot PVC antennas, installed in flat-plate configuration. Each antenna is powered by a Biomark IS1001 (ACN) and the ACNs are connected to a Biomark IS1001-MC (MTS). The antennas were built and installed by WDFW. The site is powered by a thermoelectric generator. LWE has remote communication abilities provided by a cellular modem and Campbell Scientific CR1000 datalogger. A submersible pressure transducer and temperature probe sensors are also installed to provide environmental condition data collection.

2013 1/1/2013 12:00 AM 1/1/2014 12:00 AM Multiple periods where data was lost due to buffer overruns. See 2013 event log and archive for details.
2012 1/1/2012 12:00 AM 1/1/2013 12:00 AM Multiple periods where data was lost due to buffer overruns. See 2012 event log archive for details.
2011 1/5/2011 8:30 AM 1/1/2012 12:00 AM Site operations were restored on January 5. A second array (C0) was installed on January 12 below the existing B0 array. Both arrays were removed from operation at 0830 on January 17; xceiver C0 was returned to operation on January 19 and xceiver B0 was returned to operation on February 2. A buffer error caused a loss of all data from transceiver B0 between April 5-8. A buffer error caused a loss of all data from transceiver C0 between May 5-7. Arrays were removed from May 13-May 17. Data from array C0 was lost for September 9-13. Three antennas were replaced and all antennas in both arrays are functioning as of November 3.
2010 12/7/2010 3:45 PM 12/29/2010 10:31 PM First year of operation. The lower Wenatchee River site began operating, with one transceiver array, on Dec. 7, 2010. The site was out of service between Dec. 15-29, and again between Dec. 29, 2010 and Jan. 5, 2011.

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.
