Understanding Spring Kokanee Behavior

“The thrill of Kokanee fishing has exploded over the past two decades, and it continues to grow in popularity with no signs of slowing down,” notes Loomis, who grew up fishing the productive waters of Lake Chelan. This growth reflects the unique appeal of these fish-their fighting ability, table quality, and the technical challenge they present to anglers.

Kokanee behavior in spring is heavily influenced by water temperature. “Kokanee are very temperature sensitive and they prefer water temps between 48F-54F, with optimum range being between 53-54 degrees,” explains Loomis. This temperature preference drives much of their behavior during the early season.

In early spring, particularly just after ice-out, Kokanee emerge from their winter patterns but haven’t yet established their typical summer holding patterns. The lake’s thermocline-that critical layer of water offering optimal temperature and oxygen levels-is still developing. “In the early spring the water temperature hasn’t warmed up enough to establish a ‘comfort zone’ for the fish,” notes Loomis. This transitional period creates both challenges and opportunities for anglers.

One significant factor affecting spring Kokanee fishing is lake turnover, a phenomenon that occurs as lakes transition from winter to spring. “You’re going to get turnover on your lake… especially if you’re fishing shortly after ice out,” Loomis explains.
