The Syilx Okanagan Nation Alliance has warned that Okanagan sockeye salmon returns are expected to remain low for the second consecutive year due to persistently warm water temperatures and reduced stream levels.

Current estimates suggest between 32,300 and 96,900 adult sockeye will reach Bonneville Dam on the Columbia River, but only 4,800 to 14,500 are projected to reach spawning areas above Osoyoos Lake.

This follows a trend of declining salmon populations linked to climate change, with researchers from the University of British Columbia highlighting that young salmon are more vulnerable to heat stress during migration.

The study found that Interior Chinook salmon face significant challenges when water temperatures exceed 20°C, with some fish dying after swimming in 24°C water.The Syilx Nation has declared a watershed emergency due to drought conditions, emphasizing the need for conservation efforts.While recreational fishing is prohibited this year, the alliance encourages sustainable harvesting practices to protect future salmon stocks.The situation underscores broader environmental concerns about warming rivers and their impact on aquatic ecosystems.
