Record numbers of sockeye salmon have returned to the Okanagan lakes after a 1,000-kilometer journey up the Columbia River, marking the biggest return on record for Okanagan sockeye. This achievement is due to conservation efforts by the Okanagan Nation Alliance, federal and provincial governments, and other partners, who have been working to reverse the decline of sockeye salmon caused by development, hydroelectric dams, irrigation, overfishing, and agricultural activities. The alliance's efforts include habitat restoration, creating fish passages at dams, optimizing flows for fish production, and releasing millions of sockeye salmon fry at a hatchery in Penticton each year. Monitoring programs and carcass sampling are also in place to track the health and survival rates of the population.
