Hi all
I live in Chicago, IL, and planning my first koi pond in the backyard. I want to run design ideas here to see if this will work with Chicago winter can sometimes go into -22 F. I tried my best to draw this using Excel. Hopefully, it makes sense, but please see below and the attached image file.
Parts above ground with wood wall and the rest in-ground.
1st layer (above-ground using wood) : 10 ft W x 6ft L x 2 ft deep @ around 897 gallons of water
2nd layer (in-ground) : 9ft W x 5ft L x 2ft deep @ around 673 gallons of water
3rd layer (in-ground) : 8ft W x 4ft L x 2ft deep @ around 478 gallons of water
Total: 2048 gallons of water
I currently have 8 medium-sized koi in my basement above ground pond (700 gallons) built 5 years ago. I need the space now and also the fact my koi fishes are outgrowing the tank. Any advice is greatly appreciated. Planning to start later this month and hopefully get it done before winter hit.
Again, thanks!
