Interrogation Site Metadata

The site is located on Redfish Lake Creek approximately one half mile upstream from the confluence with the Salmon River. The electronics enclosure and battery box are located on the river right bank on the back side of a storage shed used by the camp host at Chinook Bay Campground.The site consists of four 20ft HDPE antennas, located in a single string across the river. The antennas are constructed of fusion welded 4 inch HDPE pipe. Each antenna is driven by a Biomark IS1001 reader located in a submersible canister attached to the antenna. The readers are controlled by a Biomark IS1001-MC located in an enclosure on the shore. The antennas are anchored to the streambed with a through-strut method using DB-88 earth anchors attached to stainless steel threaded rod. The anchors are driven to a depth of 20-30 inches into the river bed. The IS1001 readers are connected to the IS1001-MC via Biomark CAN Bus cable. All cables are covered by flexible non-metallic conduit. Power for the system is supplied by six 12V 115Ah batteries, these batteries are run in series-parallel to create 24V to power the IS1001-MC and provide approximately 7 days of runtime.The required permits are still pending to install the complete enclosure and connect the system to AC power via an Isolation Transformer and disconnect switch. Until that time the system will be run off the above described battery system.
