FOL - Foster Dam Ladder S Santiam R

Status:   Decommissioned
Site Type: Adult Fishway  |  Organization: Oregon Dept. of Fish and Wildlife
General Operational Period: Year Round
Start Date: 5/11/2016 12:00 AM

Fish Ladder detection array at the Foster Dam Fish Collection Facility on the South Santiam River, a tributary to the Willamette River. The array is located in the fish ladder at the Foster Dam Collection facility near Sweet Home, Oregon. The site is monitored by an IS-1001-MC and five IS1001-ACNs. The hardware at the site includes the master controller, 5x ACNs, cell modem, power supply, and five antennas. The antennas are 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 in 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. 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 (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 Site is no longer active.
