PEL - Pelton Dam Ladder - Deschutes

Status:   Active - Non-Operational
Site Type: Monitored Fish Release  |  Organization: Oregon Dept. of Fish and Wildlife
General Operational Period: Seasonally
Start Date: 3/30/2016 1:00 PM

The ladder at PGE’s Pelton Dam on the Deschutes River (rkm 328.161) is used as a rearing pond for spring Chinook salmon. This interrogation site monitors the volitional release from the ladder. It consists of two antennas located on adjacent weirs in the lower part of the ladder. Each antenna is a custom built loop that monitors passage through the opening in the concrete weir. The antennas cover 100% of the flow as there is no flow over the top of the weir. The transceiver at the site is a FS1001M. The site is operated on grid power with manual downloads periodically during the season. Typical times of operation are April 1 to May 30th.
