Snuneymuxw First Nation Saves Young Salmon as Nanaimo River Side Channels Dry Up

Snuneymuxw First Nation conservation crews rescued more than 5,000 young coho salmon from drying side channels of the Nanaimo River as unusually low flows and warm temperatures stressed the fish. Many of the smolts were tagged and released into cooler main-river habitat where their survival chances are higher.

Field crews with Snuneymuxw First Nation report side channels of the Nanaimo River drying unusually early, prompting the rescue and tagging of thousands of juvenile coho and their release into the cooler mainstem where survival prospects are higher. They describe one of the driest years in memory, with warm, shallow side-channel water posing immediate risks.

Recent posts from across Vancouver Island and coastal B.C. help explain the conditions on the ground. A mid-June heatwave set new daily temperature records in multiple Island communities, including Nanaimo and Victoria, intensifying low flows and warming streams (Victoria breaks nearly 100-year-old daily weather record). Earlier in the season, researchers warned that snowpack on Vancouver Island was only about 44% of normal, a setup for faster melt, lower summer water levels, and drying pools that can trap juvenile salmon—exactly the scenario now unfolding in Nanaimo’s side channels (Vancouver Island's low snowpack likely to affect salmon populations: researchers). Similar early rescues on the Tsolum River documented precipitous drops in dissolved oxygen and fish mortalities in shrinking pools, mirroring the risks described in the post and underscoring how moving fish to cooler mainstem refuges can be lifesaving (Tsolum River salmon already need rescue as dry weather sets in). Regionally, early and elevated water restrictions in Metro Vancouver point to a broader hydrologic deficit this spring (Metro Vancouver to ban lawn watering amid early Stage 2 water restrictions), while past drought years on the coast have delayed salmon runs and led to juvenile die-offs in de-watered creeks, providing historical context for the current rescues (Lack of rainfall cause for up to three weeks of delay for salmon spawning this season). Together, these observations align with warnings that drought and heat stress can rapidly degrade salmon habitat on eastern Vancouver Island and beyond (West Coast drought puts fish and forests in dire straits; ‘It’s pretty dire’: Vancouver Island salmon under threat from climate change-induced droughts).
