Final Numbers for Cortes Island’s 2024 Chum Run

The final numbers for Cortes Island’s 2024 Chum run are in. Local streamkeepers Cec and Christine Robinson gave a rundown. 

Christine Robinson: “I think we all know that this was  a stupendous year for Chums up and down the coast. So not just Cortes, not just Quadra, not just the Sunshine Coast, but from the mainland all the way up to Alaska and down through to Puget Sound and I think possibly further south.  The numbers on Cortes were the highest that we have seen since we’ve lived on Cortes, which is now 34 years.”

Cec Robinson: “To put it in context, they’re probably three times higher than the best years we’ve ever seen. So it was pretty huge.”

Baby sockeye salmon are growing faster due to climate change. Is bigger better?

Editor’s note: Most of the salmon on Cortes Island are Chum, not Sockeye, but a DFO study of scale growth measurements from the Big Qualicum River suggests Chum are also being affected by climate change. Chum salmon appear to be growing smaller ‘due to increased ocean temperatures driven by climate changeand also the increased competition over a diminishing number of prey. There are also reports of them relocating to more northern locations. In October 2023, a University of Alaska study revealed that 100 Chum had been found in waters emptying into the Arctic Ocean. They were ‘either actively spawning or had finished spawning.’ Lead author Peter Wesley wrote, “Throughout most parts of the salmon’s range, things have gotten too warm and they’re starting to blink off. In the Arctic, the water is getting warm enough and they’re starting to blink on.”

Climate change has tipped the scales, causing juvenile sockeye salmon in B.C. to grow bigger over the past century. 

The growth of salmon using lakes as nurseries during the first years of life in northern B.C. is about 35 per cent higher than 100 years ago, a new study from Simon Fraser University shows.

Will the heavy rains come in time for this year’s Chum run in Basil Creek?

Part 1 in a series of articles about the Fall 2023 Salmon runs; Click here for Part 2.

Very little water is trickling through Basil Creek, where Cortes Island’s principal Chum run occurs in late October. There have been few days of rain on Cortes since May, and some of the area’s shallow wells stopped producing in July. Only about 10 Chum were seen in Basil Creek during the 2022 drought. Unless water levels rise, this may be the second year in a row when there is not a significant creek for the Chum return. 

According to the Pacific Salmon Foundation, BC is going through ‘one of the most extreme periods of drought in recorded history.’

Saving the Cowichan Estuary from drowning in a climate-fed ‘coastal squeeze’

Canada’s National Observer, Local Journalism Initiative Reporter

High atop a dike hemming the Koksilah River as its fresh waters meet salt, red-winged blackbirds call out as they patrol their territory.

Noisy heralds of spring, the blackbirds return to the Cowichan Estuary each year to nest and protest human intrusion with sharp signature trills from the brush along the riverbank.

Today the interloper is Tom Reid, conservation land management program manager with the Nature Trust of British Columbia (NTBC), who stands atop the 15-foot-high rock embankment he is working to destroy.

The dike, built to fortify farmland stolen from the estuary, is stifling the tidal marsh vital to the survival of a host of endangered salmon and bird species that rely on it for breeding, feeding and migration, he said.

No Chum in Basil Creek yet, but the outlook for salmon may be improving

It is November 26 and there are still no Chum Salmon in Basil Creek. Normally they would have returned a month ago, but there was a prolonged drought this year. While the water level has risen, there are still no fish.

“It’s getting to be late for Chum, but we’re seeing other populations come in late. We might see Chum return into the next few weeks, it’s very possible. This year is definitely characterized by a lot of weird conditions,” said Matthew Clarke, DFO’s Head for stock assessment in North Vancouver Island, from Black Creek to Cape Caution (which is actually on the Mainland). His area also includes Cortes and Quadra Islands.
