Pond design

[Dez]

I have a 24" deep pond in Edmonton and I overwinter my fish in it. There's a pond build journal somewhere on Canreef in the Lounge. Mine's only about 4000 gal. There are many different ways to over winter the fish in a shallower pond. Mine is 33' x 17' with many koi. It is in sun for most of the day and I have clear water. Filtration is key-to create an ecosystem. Tests have shown that it is difficult to grow algae in full sun in aged healthy pond water. Hope this helps. I've been ponding for 7 years now.
