Mid Columbia Koi & Pond Club
Our club began in the mid 1980s when several koi lovers got together and decided to combine their knowledge and experiences and encourage other koi and pond lovers to join them. The club became a part of a bigger group when it joined the Pacific Northwest Koi Clubs Association in 2000. Being a part of the PNKCA has afforded the club’s members a huge resource through educational convention seminars—plus the company and friendships of others who also love this fun, if not at times daunting, hobby.
