CHL - Lower Chiwawa River
Status: Active - OperationalGeneral Operational Period: Year Round
Start Date: 3/3/2008 12:00 PM
This is a permanent instream PIT tag interrogation site at rkm 1 on the Chiwawa River. The site consists of two rows of antennas, with each row spanning the wetted width of the channel during base flows. Each row consists of 3 20-foot PVC antennas, installed in flat-plate configuration. The FS1001M transceiver is powered by grid. The antennas were built and installed by WDFW. A cellular modem is installed on site to provide remote communication and allow for automated data collection. A submersible pressure transducer and temperature probes are installed on site to monitor environmental conditions.

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.
