Washington Koi and Water Garden Society

Welcome to the Washington Koi & Water Garden Society. We are a group of koi keepers and water garden fanciers who enjoy getting together on Zoom, pond tours, field trips, and summer outdoor meetings, including last year’s Koi Fest. Prior to the Covid outbreak, we put on koi shows for 28 years. We share ideas and help one another and provide a monthly newsletter with relevant articles to members.
During membership meetings, we have educational programs on koi health, pond construction, koi varieties, aquatic plants, nutrition, filtration, and water quality, among others. We are a non-profit hobbyist organization, and we are affiliated with the Pacific Northwest Koi Clubs Association and Koi Organisation International. Our Executive Board meets regularly to plan a variety of activities for our membership.
We suggest that if you are even thinking about constructing a koi pond, join a koi club such as ours and get as much information as possible before taking that first shovelful of dirt. Also, it isn’t necessary to have koi to enjoy ponds. Beautifully planted ponds or ponds with goldfish, or even pondless waterfalls provide pleasurable moments to WK & WGS members, even though our focus is on koi, our “living jewels.”
We are a koi community, and we are here to help.


Upcoming Events and Important News
July 26, 2026 Membership Meeting WK & WGS
Macneil/Moore Pond
2 p.m.
Back Deck Discussion of Water Testing
How and Why.
Keeping Koi is really Keeping Water. Learn how to test and why testing is so important to keep Koi healthy. This review is especially important for new hobbyists or those who need a refresher. We will meet on the back deck (fingers crossed there will be sunshine) and discuss KH, pH, Ammonia, Nitrite, Nitrate, tricks of testing, keeping records, and more. Discussion led by Nancy Moore, Certified Koi Keeper (K.O.I.) and Koi Health Advisor (via AKCA in its heyday).
If you would like, bring a water sample from your pond and your water source (baggies work just fine).
