Designed and build your own water garden Koi pond. I visited Japan a number of times and always admired their Koi and water gardens. Our Koi pond design has three ponds, the top pond has water hyacinths that float on the water and filters it, the water is very clear. Water falls from the top pond and aerates the water in the middle pond. The main pond is about 2000 gallons of water where the Koi and water lilies thrive.
It is very soothing and relaxing to sit beside the pond listening as the water tumbles down a small water fall. The dragon flies are darting in and around shrubs and plants, crickets are chirping, bees are buzzing and humming birds are flittering around. I can sit for hours in a lounge chair listening and watching this while the Koi swim lazily around in the pond.
We have about 6 water lily plants with large pink and red blossoms in the bottom water garden pond. They cover almost all the pond in the summer time but they die off back to their roots in the fall and re-grow in the spring as the days get warm and long.
I have about 40 Koi in the pond, it is hard to get an accurate count as they never stop swimming. I purchase small Koi, 2 to 3 inches long and place them in the pond. They will grow to over 10 inches long.
We have unwanted visitors to our water garden pond. Egrets will stop on our or the neighbors roofs then fly down and wade into our pond. If we see the egret, we will let our dog out to scare off the egret.
The raccoons like to play in the pond and sit on the water lily containers. I saw a mother and 3 baby racoons play and try to catch the Koi in our water garden pond.
I laid out the pond design for our do it yourself Koi pond, with stakes and string. I laid down 3″ PVC pipes to pump water from the lower pond to the top pond. I treated the block wall with asphalt paste as I piled dirt against this wall. I stacked 4 railroad ties two layers high in an L shape to make the front edge of the upper pond and to make the waterfall.
I constructed a 1/4 circle ridge from the ends of the ties to make the front edge of the middle pond where water would tumble over the edge into the bottom pond. I removed about 18″ of dirt for the lower pond, putting the dirt into the walls of the upper ponds. I put a PVC liner that we cut and glued to fit over the ponds.
I started with a 1/5 horse power above ground pump with a 2″ inlet and outlet. This provided a good flow of water over the waterfall. Sometimes it would lose its suction and I would have to re-priming the pump.
I found a 1/3 horse power submersible pump that could be used in a fish pond. Some pumps cannot be used in a fish pond, check the fine print. I found this out the hard way when I tried to get a replacement pump.
I designed and built this water garden pond about 15 years ago and we have had good luck with it. The raccoons and egrets like it also.
