Thanks to a radiotracking program begun this spring, fisheries biologists confirmed yesterday that two radio tagged bull trout have migrated through Glines Canyon and are now upstream of the former Lake Mills in Rica Canyon.
Two other bull trout have also been detected above Glines Canyon, but were not located during the ground survey yesterday.Biologists will use fixed-wing aircraft to conduct watershed-wide surveys this fall.
"To witness these first fish to migrate above Glines Canyon is both amazing and inspiring," said Olympic National Park Superintendent Sarah Creachbaum.
Both of the fish currently in Rica Canyon were tagged earlier this summer at locations below the former Elwha dam site.
The radiotracking program is possible through partnerships with the Lower Elwha Klallam Tribe, the U.S. Fish and Wildlife Service and Washington's National Park Fund, allowing biologists to monitor the movements of radio-tagged salmonids in the Elwha River.
Each fish is equipped with a a uniquely coded radio transmitter that differentiates it from all other tagged fish. Radio signals from the tags are then detected by radio receivers and antennas.Six telemetry stations were installed between the mouth of the river and just above the Glines Canyon dam site. These stations continually scan for and record data, documenting when individual fish pass by each station.Biologists also manually track fish between Rica Canyon and the river mouth using handheld radio receivers and antennas.
Eighty-seven anadromous fish have been radio-tagged so far.Of that total, 13 bull trout, 2 winter steelhead, 5 Chinook and one sockeye salmon have been located above the old Elwha dam site.
More details on the migratory bull trout located above Glines Canyon yesterday.
