The chief of the Adams Lake band remembers stories of the Upper Adams River early summer run containing sockeye salmon weighing 20, 30 and 40 pounds.
“They were so numerous you could walk across the river on their backs,” Kukpi7 (Chief) Cliff Arnouse recounted.
It’s memories of what once was that helped spark a pet project of his, a salmon restoration program on Adams Lake.
“The salmon that returned to the Upper Adams River and Adams sustained our community for thousands of years and it is imperative that we see this run returned to its former glory,” he said.
Adams Lake is now very low in nutrients, classified as an ‘ultra-oligotrophic’ lake.
“This ultra-oligotrophic classification is consistent with the collapse of the Upper Adams River sockeye run over a century ago, as the lake no longer receives the input of marine-derived nutrients on an annual basis to sustain its historical productivity,” stated a news release from the band.
With not enough fish coming back to die and creating nutrients, there’s not enough nourishment to help the small fry survive in the lake, Arnouse said. He said logging and splash dams destroyed a lot of salmon eggs and stirred up silt over the years.
The band has been requesting action and negotiating with the federal government for some time, he said, so the project is a welcome one. It comes from a proposal submitted by Arnouse.
Nutrients, in the form of agricultural grade liquid fertilizer, will be applied to the lake using a boat.
Fertilizer additions will start in mid-April, 2021, and be applied weekly in a designated treatment area of the lake until late August. The four-year program began on April 1, 2020 with an extensive one-year lake pre-fertilization monitoring program.
Arnouse gave credit to the Okanagan Nation, who Adams Lake partnered with, as it has experience in the fertilization and enhancement of fish habitat in Okanagan Lake.
“The sustainability of this culturally and ecologically important species hinges on our ability to listen, work together and apply innovative techniques to increase wild sockeye salmon production in B.C.,” said Fin Donnelly, B.C. parliamentary secretary for Fisheries and Aquaculture. “I thank Kukpi7 Cliff Arnouse and the Adams Lake Indian Band for implementing this important project and look forward to monitoring its progress over the next four years.”
Arnouse said it will take a long time to educate everyone up and down the Fraser to understand what the band is trying to do to restore the early run, but it will be beneficial to everyone.
“Salmon is one of our most sacred foods, it sustains us and it also ties us all together…”
