Question about pond volume/depth

[Gemma]

If I'm understanding gas exchange and water circulation/oxygenation correctly digging deeper is not necessarily a good thing, I know it has to do with surface area, so my question is: is there a surface area to depth ratio formula? I really don't want to dig too deep trying to increase volume and end up creating a bigger issue

 

[MitchM]

Gemma, rule of thumb for surface area to depth is 20:1.

 

[Gemma]

20 sq. feet of surface area to 1' of depth?

 

[MitchM]

Right.

 

[Gemma]

Thanks @MitchM , I don't even have to do the math to see that I'm pretty safe going down 4'!
...lol unless you're joking

 

[MitchM]

No I'm not joking.

I remembered he discussed it at sometime.

Meyer was really smart. I didn't realize he wasn't still with us until the other day. Sad. I guess I'm safe at an average of 3 ft depth and about 140 Sf of surface area. I never knew there was any type of formula for that but always valued surface area with any pond I had. However I'm sure if someone has lots of O2 pumped in the pond you could go deeper. I saw a pond one time that was really deep.. I think about 15 ft. The owner raised high quality Koi and he wanted to keep the water cool so they wouldn't hurt themselves spawning.

 

[MitchM]

Right, plus there are other factors - sloped walls, straight walls, close to the equator, far from the equator...

Lol you're one of those people I never know if you're serious or if you're joking!
As for Meyer, he lives on through all of us! Every time we think, mention, remember him, he is close to us!

@Gemma That’s an excellent question! @MitchM (Meyer) for the info!

As far as volume of Water goes...before you fill your new pond, get one of those water counters you connect to your hose and you'll know exactly how much water you're dealing with. It's great to know your volume for many reasons.
They are very cheap to buy. I have one I bought on Amazon that connects to the end of my hose. It's digital and I think it was maybe $10-$20. We'll worth it.

Thanks and whew! I'm glad it went well, I was debating whether or not to even ask this question,for fear no one would understand what I was saying

Yup, our supplier is going to lend us his!

I have a raised wooden hexagonal pond 175 gallons 2 Koi 3” and 1 goldfish 3 shubunkins. Planted with yellow flag iris, bullrushes, purple bearded Iris and a bundle of floating plants. When the sun shines 3/4 of the pond is shaded. It has a hozelock ecopower+ 6000 with uvc and waterfall return.

Wow! Very old thread!
It would be best if you started your own new thread and introduced yourself.

You made a statement and a good description of your pond, which is great.

If there is something you need help with, just ask, but start a new thread.
