Well, an estimate 6k gallon anyway, we suspect it's closer to 7k actually. I set-up a Picasa Slideshow for this, as I figured it'd be easier to share all photos that way.
The first set of 5 pics show off the pond my dad set up while we were living in Minnesota, before moving to Nebraska some years ago and setting up the new one. During that time the koi had to be housed indoors during winter as the water would freeze all the way to the bottom. That pond was up and running for about 3 years. The new pond is older than 5 years by now. The bigger koi are over 7 years old now, they are the first generation my dad had. They're nice, big and healthy [they look a lot smaller in the pics]. Also, since these pictures have been taken I think our population has almost doubled. We definitely have to start selling or giving them away As you can probably notice the pond starts off shallow, about a foot deep and goes all the way slightly up above one's waist in depth. The koi are in the pond year round, during winter they sit at the bottom in the deep point where temp at the absolute lowest is around 4*C/38*F and the water never freezes. Dad uses a heater/de-icer to keep a hole going to allow proper gas exchanges. Most of the plants come indoors during winter except for the water lilly.
My dad's pond, his pride and joy.
