LEL - Leaburg Dam Fish Ladders

Status:   Decommissioned
Site Type: Adult Fishway  |  Organization: Oregon Dept. of Fish and Wildlife
General Operational Period: Year Round
Start Date: 5/23/2018 12:00 AM
End Date: 7/8/2019 12:00 AM

Fish Ladder detection arrays at Leaburg Dam on the McKenzie R, a tributary to the Wilammette R. The arrays are in the east and west ladders near the upstream ladder exits. The site includes an IS-1001-MC and four IS1001-ACN’s, cell modem, power supply and four antennas. The antenna configuration for the West ladder consists of two full spanning pass-thru antennas, one immediately adjacent to the other. Detection for the MC is set at both HDX and FDX detection to enable detection of Salmon/Steelhead, Bull Trout, and Lamprey. The East Ladder has a full-spanning pass-thru antenna and a ladder-window antenna that interrogates the volume of water immediately adjacent to the viewing window located in the fish ladder. Each configuration allows for determining system efficiency. The antennas are all custom-built with ferrite shielding and 10 ga Litz-wire. The site is on grid power, with battery back-up. The site is on EWEB property, and managed by the Eugene Water and Electric Board. Site is no longer active.
