Cause of kokanee die-off in Okanagan Lake uncertain

KELOWNA – Provincial officials are puzzled by a die-off of kokanee salmon in Okanagan Lake.

More than 1,000 kokanee have been found washed up on the northern half of Okanagan Lake shorelines since May 25, according to a media release issued by the province today, May 31.

Samples from the die-off have been sent to the Provincial Animal Health Centre where they are being tested for disease. Results are expected within two weeks.

Officials say the die-off is not significant enough to pose a threat to the lake’s overall kokanee population.

Last year’s fish census counted more than 180,000 spawning kokanee, equivalent to the average return over the past 10 years.

I have been looking for news in the South Okanagan - SImilkameen for 20 years, having turned a part time lifelong interest into a full time profession. After five years publishing a local newsletter, several years working as a correspondent / stringer for several local newspapers and seven years as editor of a Similkameen weekly newspaper, I joined iNFOnews.ca in 2014. My goal in the news industry has always been to deliver accurate and interesting articles about local people and places. My interest in the profession is life long - from my earliest memories of grade school, I have enjoyed writing.
As an airborne geophysical surveyor I travelled extensively around the globe, conducting helicopter borne mineral surveys.
I also spent several years at an Okanagan Falls based lumber mill, producing glued-wood laminated products.
As a member of the Kaleden community, I have been involved in the Kaleden Volunteer Fire Department for 22 years, and also serve as a trustee on the Kaleden Irrigation District board.
I am currently married to my wife Judy, of 26 years. We are empty-nesters who enjoy living in Kaleden with our Welsh Terrier, Angus, and cat, Tibbs.
Our two daughters, Meagan and Hayley, reside in Richmond and Victoria, respectively.
