One of the largest sockeye salmon runs in the world, fish are born in the river before spending their first year in Shuswap Lake. The sockeye then travel to the ocean, where they spend two-to-three years avoiding predators and growing. Their life cycle ends as they make the 500-kilometre trek back to the Adams River to spawn. As the fish operate on a four-year cycle, 2019 is a considered a sub-dominant year for sockeye returns. The next dominant return is in 2020. To coincide with the anticipated optimal sockeye run viewing timeframe, the Adams River Salmon Society will host a free interpretive walk Wednesday, Oct. 9 at 10 a.m. and 12 p.m. Interpretive guides will also be available during the long weekend. The non-profit organization is also preparing for fall market Oct. 12 to 14.
