ICU is a permanent instream PIT tag interrogation site at RKM 10 on Icicle Creek. 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 three 20-foot PVC/HDPE antennas, installed in flat-plate configuration. Each antenna is powered by a Biomark IS1001 (ACN) and the ACNs are connected to a Biomark IS1001 controller. The antennas were built and installed by WDFW. The site is connected to grid power. Site was shut down in May 2023, until funding was found to update equipment in late July of 2024. Array may be turned off during winter months.
