Fish Ladder detection array at the Minto Dam Fish Collection Facility on the North Santiam River, a tributary to the Wilammette River near the town of Gates, OR. The site is monitored by an IS-1001-MC and five IS1001-ACN’s. The hardware at the site includes the master controller, 5x ACN’s, cell modem, power supply and five antennas. The antennas are all custom-built pass-thru antennas with ferrite shielding and 10 ga Litz-wire (the Flume Antennas are 12 ga ribbon wire). Two antennas are side by side located within the collection flume, one antenna is near the midpoint of the ladder near the powerhouse, and two antennas are on the downstream end of the ladder near the entrance at the North Santiam River. The site is powered by grid power, with battery back-up and a charging switch for alternating battery-banks. The site is on Federal property managed by the Portland District US Army Corps of Engineers. The collection facility is managed by the Oregon Department of Fish and Wildlife. Site is no longer active.
