Backyard Fish Pond

That pond looks surprisingly deep.
It's hard to keep the water that clear. If it freezes during winter most fish are in trouble. I believe the weather is quite the same over there as it's over here in Finland. Shallow ponds freeze all the way to the bottom here....

Built one for my parents, in BC.
About 30" Deep, 7' Round. Basic pump and filter.
Koi are surprisingly tough and can survive the cold.
For winter, buy a good floating heater to keep air circulating. Mom bought a shitty one. Died and so did the fish. Now they live in a tank inside for the winter.

Build where large birds cannot easily land, or put trees around it. No problem with vermin, but have no weasels around. Frogs will eat smaller fish though.

Thems cold-blooded animuls, doubt they GAF - assuming, the pond aint totally frozen. Think it needs to be about 3 feet deep minimum for Koi anyway, how much deeper so it don't totally freeze?- depend on your local climate, I s'pose.

Whereabouts in BC? Climate can vary greatly in the different regions of that province. I am in southwestern Ontario.

I was hoping to build 4 feet deep. Never thought about bringing the koi inside for the winter but it is an option.

Okanagan Valley. Fish have been in the pond for 3 weeks now. Temps dropped to -35 and pond froze to the bottom.

Regardless of how much ice there is, it can't freeze over and deplete the air.

Pond liners are expensive. Can plug in a heater. Most fish can live under oce if its deep enough. Research it some and get to digging op. Post results

Build a green house around it.. no fuck it put it in the center of your bedroom.

not to hijack your thread OP but as a quick side, how much would it cost to build / maintain a pool like pic related ?

My parents had two ... one we threw together ourselves and later one from a landscaper.

The one we threw together ourselves pumped the water through an overgrown planter (a bog filter) and about 3 meters of shallow water way with lots of stones, gravel and plants. The landscaper one had two of those filter barrels ... the one we threw together ourselves stayed a lot clearer. Especially since my parents don't want to bother to replace the filter media in the barrels.

We also have a ton of leaves which fall into the pond. In retrospect we should have just covered the entire bottom with fake stone liner instead of the gravel we used, which just collects crud and is hard to clean.

> Will this attract rats, weasels and other vermin to my property?

It might attract bullfrogs ...

Mosquitos will lay their eggs in the water

You have to have something agitating the water, like a fountain.

Not speaking from personal experience, but I know some people who have ponds like this in my country (Norway). As you said, they will freeze solid in the winter and as such they will usually be drained once the cold sets in.

You could put polystyrene under the pond liner and cover it with something like SolaWrap (high strength bubble wrap) during the winter. Wouldn't need a whole lot of heat to keep it liquid at that point.

I buried an old hot tub I sealed and decorated two years ago and even when the top is frozen a half inch solid my little walmart goldfish keep swimming around down there. I do try and break the ice every few days, but goldfish are cheap and metal af fwiw.

More than you can afford, pal.

Plenty of online literature for this.

You want to use a pond liner. You want to create flat steps. You want to look up the freeze depth of where ever you live. Always dig 6 in more than that to be safe.
Use a natural filtration method. That is lava rocks and pea gravel and you seed these filtration with bacteria every year. Use a pond heater during the winter. Make sure your pond has good flow from the filtration to the pump. Don't design something with areas of water that doesn't move. Don't build it in a place already muddy/with poor drainage. It will life the pond liner up.
Look it up if you have questions after you do some studying they'll get answers.
