Thousands of salmon found dead as Canada drought dries out river
A lack of rain on the western coasts saw 65,000 dead salmon wash up on the creek

Tens of thousands of dead wild salmon scattered along a creek bed are the latest casualty of a drought that has gripped the province of British Columbia for more than a month and left communities bracing for more devastation.
In a video clip posted to social media, the carcasses of pink and chum salmon are seen piled near the community of Bella Bella.

This is Neekas, Heiltsuk Territory. All of these salmon went into the creek, the creek dried up b/c of no rain so far this fall, and just died, and this is just one reach! Global warming is killing everything. This is such a sad scene. Video credit, Sarah Mund
“It’s just devastating to see this happen. River levels [are] low everywhere right now – not just in Heiltsuk territory. This drought is coast-wide right now,” William Housty, conservation manager with the Heiltsuk Nation, told the Guardian. “We see pre-spawn mortality on [an] annual basis. But never to this degree.”
The video was taken last week by German researcher Sarah Mund, who joined a crew on a stream walk to gauge the health and size of salmon populations returning to spawn.
Wild salmon typically wait for rains as their signal to journey up creeks and rivers – an indicator that water levels will rise and provide easier passage to natal streams.
Housty says a brief afternoon rain 10 days ago, coupled with a high tide, gave the salmon a false signal to start.
No more rain came and the creek dried up, leaving the fish stranded.
“We’ve had one afternoon of rain in more than a month,” he said. “Without the rain and tide, I suspect a many of those salmon would have likely been holding [in the ocean] and waiting. They haven’t had enough time adjust to the reality of this drought.”
One biologist estimated there were 65,000 dead salmon in the creek bed – more than 70% of which failed to spawn.
The life cycle of wild Pacific salmon means they inevitably die after travelling up winding creeks and streams. But their remains, consumed and redistributed by scavenging bears, wolves and birds, provide valuable nutrients for the forest.
Housty says the deaths come at a time when the community had been optimistic about the recovery of both pink and chum populations.
The coaster waters of the Heiltsuk have long home to healthy chum populations, but those numbers have declined in recent years, part of a broader collapse of wild salmon.
“It’s heartbreaking to see this. It really felt like we were turning the corner on their recovery,” Housty says.
British Columbia’s western coasts have seen little rain over the past five weeks and several regions are in drought level four, which the province says will probably lead to socioeconomic and ecosystem impacts.
“It’s something we have to keep monitoring. I hope this is a rare event,” said Housty. “But we need to be prepared to help the salmon when possible, in any way we can, to avoid something like this again.”
There can be no more hiding, and no more denying. Global heating is supercharging extreme weather at an astonishing speed.
Guardian analysis recently revealed how human-caused climate breakdown is accelerating the toll of extreme weather across the planet. People across the world are losing their lives and livelihoods due to more deadly and more frequent heatwaves, floods, wildfires and droughts triggered by the climate crisis.
At the Guardian, we will not stop giving this life-altering issue the urgency and attention it demands. We have a huge global team of climate writers around the world and have recently appointed an extreme weather correspondent.
Our editorial independence means we are free to write and publish journalism which prioritises the crisis. We can highlight the climate policy successes and failings of those who lead us in these challenging times. We have no shareholders and no billionaire owner, just the determination and passion to deliver high-impact global reporting, free from commercial or political influence.
And we provide all this for free, for everyone to read. We do this because we believe in information equality. Greater numbers of people can keep track of the global events shaping our world, understand their impact on people and communities, and become inspired to take meaningful action. Millions can benefit from open access to quality, truthful news, regardless of their ability to pay for it.
