Interrogation Site Metadata

SFC - Cougar DamTailrace SF McKenzie

Status: Active - Operational

Site Type: Spillway | Organization: Oregon Dept. of Fish and Wildlife

General Operational Period: Year Round
Start Date:

The Cougar Dam PIT (Passive Integrated Transponder) detection array is installed in the Regulating Outlet (RO) and turbine tailrace of Cougar Dam on the South Fork McKenzie River in Oregon. The array consists of six antennas: four located on the river-left branch originating from the RO, and two on the river-right side at the turbine outlet. The system employs a Biomark Master Controller along with six individual IS-1001 readers connected to each antenna. On the RO side, two antennas are ferrite-shielded flat plate antennas designed to focus the electromagnetic field for improved detection efficiency while minimizing interference from surrounding metal structures. The other two are large PEX loop antennas situated just downstream of the RO sill, optimized for detecting tags in a wider detection zone. On the turbine side, both antennas are floating PEX loop antennas located at the confluence where water from the turbine outlet joins the main river. These floating designs adjust to changing water levels and flow conditions, ensuring consistent detection performance. The site is grid-powered and operates year-round, providing continuous monitoring of fish migration through the dam's outlets.

Operational History

Operational history describes the period the site was interrogating for PIT tags. The comments provide anecdotal information about the operation of the site during this period. Site operational periods are updated typically at the end of the calendar year.

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.
