PEL - Pelton Dam Ladder - DeschutesStatus: Active - Operational
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, and as a trapping facility for returning adults. This interrogation site monitors the volitional release from the ladder as well as the weirs downstream of the trap for adult trap collection of broodstock and trap-and-haul operations. It consists of two antennas located on adjacent weirs in the lower part of the ladder (for juvenile/smolt detections), and two antennas on a ladder-weir that monitor adult returns. Each antenna is a custom built loop that monitors passage at the concrete weir. The antennas for juvenile detection cover 100% of the flow as there is no flow over the top of the weir. In addition, the antennas downstream of the trap also cover 100% of the flow on one weir. The transceiver at the site is a IS-1001-MC that is networked to individual IS-1001s located near each weir. The site is operated on grid power with automated downloads daily. Typical times of operation for the juvenile antennas (Antennas 1 and 2) are from April 1 to May 30th. While the adult ladder antennas (Antennas 3 and 4) operate year-round.

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.
