You aren't finding area correctly then because the formula for area is Pi* R^2

So area of a 5ft radius circle is: 3.14*5sq= 3.14*25= 78.5 ft sq SA
The area of an 8ft radius circle is: 3.14*8sq= 3.14*64=200.96 ft sq
And 200.96-78.5=122.46 ft sq= SA

Then 122.46* 3(depth)= 367.38 ft cubed

367.38 ft cubed= 2748.19 Gallons

You have the right ideas...

pond is 5' center, outside diameter is 5'+3'+3' (3'wide on each side of the inner circle). Area of circle is 3.14 * (1/2 * diameter) squared. thus about 380sq ft - 19 sq ft and multiplied by 3' and converted to gallons (7.48 per sq ft) is about 2700 gallons. The first estimate is close.

I loved the idea of a moat, i want one around my entire house. one of these childhood dreams.

What part of washington do you live in garden zone? That would help a lot for what you can grow and fish you can use.

Not to over kill this Andrew but I read your drawing wrong when I calc. pond volume. After reading your post again I realized the garden was ten foot wide, a radius of five feet. The three foot moat would make the garden/moat sixteen feet wide, a radius of eight feet.

So the 2500/2750 gallon volume calc. by you and others is correct. Sorry for my error and any confusion.

Over 13 cubic yards of soil to excavate and relocate. Quite a weekend of work. Hope you have a few good buddies and sandy soil.

Andrew - If this a dream of yours go for it. We can accomplish anything we get determined about.

I got the same reaction 25 yrs ago when I put in a 300+ ga, concrete pond in my patio. Yes, it was a lot of hard work that my detractors would have wanted no part of. To me it was cathartic, I enjoyed the challenge and I feel worth every drop of sweat.

I think one of the greatest motivator is your peers saying you can not do something and few things in life are sweeter than showing them you can.

Best of luck with this, I hope to see pics when you're finished.

Definitely follow your dream.

I use to park my truck on a side street in Culver City, CA during one of my routine UCLA clinic deliveries and one day I noticed this body of water in front of this old rustic looking house. This guy converted his whole front yard into what looked like a blackwater pond with weeping tree trunk and all. One of these days I'm going to drive down and take a closer look. At the time, it was just an old house and a yard with dirty water in the middle of the city to me. Now I'm wondering what kind of fauna resides in such a cool pond.

Coming from someone who grew up on the WA west side, our weather is really nice and mild, with only a bit of freezing in the winter. No real extremes during the summer either, which is nice.

As for building this, have you thought about renting an excavator? Would make something like this go real quick, although it might damage the land around it. Whatever you do, go for it, I want to see this happen.

Also, reminds me of this: (Ring of life at the Seattle Aquarium)

if I wanted it to look tropical what type of plants should i use?
Also, I've decided In May I'll dig the pond then I'm gonna add a bunch of rosy reds and cherry shrimp first then I'll add goldfish and koi around June then add 2 3" bass near the end of August. (How many goldfish and koi should i add?)

I'd like to make it look like one of the high mountain lakes (obviously smaller) in Oregon the picture is of one i fished at this last summer to show what I'm hoping for
