Interrogation Site Metadata

TC4 - Trout Creek at 43 Road Bridge

Status:   Active - Non-Operational
Site Type: Instream Remote Detection System  |  Organization: U.S. Geological Survey
General Operational Period: Year Round
Start Date: 9/15/2014 12:00 AM

An instream interrogation system consisting of two antenna arrays at rkm 11.0 of Trout Creek, a tributary of the Wind River, WA. The site is at the bridge where Forest Road 43 crosses Trout Creek. Each antenna array has three 20-foot antennas covering a total of 60 feet, which spans the wetted area of the stream at most flows. The transceiver is a FS1001M. Power is provided by solar panels charging a battery bank. Downloads are manual and typically done during weekly site visits, though that interval may be longer during winter due to snow.
