I was going thru my photos and decided to post pics of my new 480 gallon pond (4x8)that we built a few months ago.
It houses my 13yr slider, 2 goldfish that my kids won at the fair 2yrs ago and a new baby calico colored koi.

Then we added insulation board and plastic over that so when we added sand it wouldn’t spill out when it rained.

Added the liner which was very time consuming and isn’t perfect but we did fold the corners like some YouTube video showed me. I practiced with wax paper and a shoe box.

Then we cut a notch out in one corner for cords and a pvc pipe as over flow drain. It worked pretty good with all the rain we got in San Diego this spring!

Capped it

We found an old eater pump on the property when we moved in so we tried to clean the inside because it was rusty and corroded so we put aquarium hose thru so the water didn’t touch it but we had to buy some adapter thing to fit on the pump hose and aquarium hose.

It works!!!

I added a resin patio table I wasn’t using and the turtle ramp that I have used for about 10yrs.

I just added a Pondair2 to help aerate and move water around on the far end. I love the bubbles and so do the fish and turtle.

I added pond plants but everyone devoured them! [emoji51]

Two days of hard work paid off thanks to my husband!!

There’s a few things I’ll add later.
I want some hides and branches for them.

Stay tuned for our next project starting Monday! It’ll be in the tort enclosure section!![emoji217]

Hello. We are working on a design for a remodeling lakefront home that slopes toward the lake.

The best available place to put my koi pond is on a sloped part of the property. I'm envisioning a pond that starts at ground level up hill and is contained by a wall downhill. I can't figure out how to accomplish this. I've tried using retaining walls, but they just don't reach high enough.

I'm sure there is a way to do this, but I am not experienced enough with terrains to figure this out. Help would be greatly appreciated!
