The interrogation site is an instream array in lower Clear Branch located approximately 500m downstream of the Clear Branch Dam. The site uses a single 15 ft PVC cased antenna installed in a pass-over configuration in the tailout of a pool where Middle Fork Irrigation District has a stream gauge. The interrogation site may be operated seasonally or year round depending on winter access and specific needs for monitoring projects or passage studies occurring at Clear Branch Dam. The antenna is controlled by a Biomark IS1001 ACN reader. Power is provided by solar panel(s) charging a deep cycle battery bank. Interrogation data is manually downloaded periodically. Site is no longer active.
