Pond to bog rule of thumb?

[koshki]

I don't know why I haven't been able to find this via search, but I remember that there is a pond/bog ratio to size it correctly. Can anyone help me out? I'm trying to design a new pond in a small space.

TIA

15% minimum for no or very low fish load. 30%+ koi/swim pond. Anything is better than nothing, and no such thing as too big.

Thank you!

Just for clarification...that's 15% of total volume, not just surface area?

No, that’s surface area. That’s just the rule of thumb. No idea why it is the way it is. Trial and error I suppose. Some folks go by volume, too.

As a point of reference, my bog is 20% of my goldfish pond surface area and works fine, but if I knew then what I know now, I'd have made the bog larger because I like planting in it so much.

If you're real tight and funds arent the desiding factor a shower and rdf are also good options ..
