Interrogation Site Metadata

STR - SF Salmon Satellite Facility

Status:   Decommissioned
Site Type: Hatchery Returns  |  Organization: Idaho Dept. of Fish and Game
General Operational Period: Seasonally
Start Date: 6/24/2010 12:00 AM
End Date: 7/24/2019 12:00 AM

This array is located in the ladder of the South Fork Salmon River adult fish trap. The array consists of four antennas, a top-water (30 x 60) and submerged (12 x 15) antenna on both a down-ladder dam-board and an up-ladder dam-board. All fish migrating up the South Fork that try to migrate upstream of the satellite facility are forced into the ladder via a removable weir. This weir is a permanent structure with removable panels that is very effective at blocking the upriver movement of fish. Fish have the freedom to move into and out of the ladder at will and are not trapped until they jump a finger weir that is above all array antennas. Adult Chinook salmon that swim past the array and enter the ladder are sorted by origin. Natural origin fish are returned to the South Fork above the weir while hatchery origin fish are typically ponded and latter spawned, recycled through the fishery, or released elsewhere in the basin. Site is no longer active.
