There are 2 formulas that give roughly the gallons of a pond:
LXWXDX7.8 gallons (right or 7.5?)
Circle? Anyone have that info?
The way to more accurately figure is using salt. See Roark's salt
calculator at www.click2roark.com
And most accurate, a water meter. ~ jan

Volume of right circular cylinder (circle, vertical sides, flat bottom)
V=pi*r^2*h. volume (cu. ft.) times 7.48 equals US gallons. 22/7 is close
enough for pi (355/113 if your finicky). Multiply by the semi-diameter,
then multiply by the semi-diameter again. Then multiply by the depth. This
is the volume of the pond. Multiply by 7.48 for gallons.

7.48 gallons in a cubic foot.
3.14* diameter*Depth * 7.48 = gallons (diameter and depth in feet)

There are 2 formulas that give roughly the gallons of a pond:
Rectangle or square:
L x W x D x 7.48 = gallons
Circle;
3.14 x Diameter x Depth x 7.48 = gallons
Measurements in feet.
The way to more accurately figure is using salt. See Roark's salt
calculator at www.click2roark.com
Thanks Nick & Geoff. Hopefully the above was interpreted
correctly. ;-) ~ jan

3,14*diameter gives you the circumference of the circle. When multiplied by
the depth, it gives you the surface area of the right circular cylinder,
not its volume.

Okay.... your explanation either went over my head or I didn't understand
the symbols used. Can you put it in a more simple form perhaps? Tx, ~ jan

If it's oval rather than round (i.e. an ellipse), then volume =
(length of major axis, ft) times (length of minor axis, ft) times 22
times 7.48 divided by 7 divided by 4, US gallons. If you want it in
Imperial (UK) gallons, replace 7.48 by 6.23

OK, Jan. The circumference is the distance around the circle. Say you have
a round pond that's ten foot across. You'll need 31.4 feet of edging
stones. Say it's ten feet deep and you want to tile the side. You'll need
314 sq. ft. of tile.
It would hold 3.14*5*5*10*7.48= 5872 gallons.

I agree with Chris. The area of an ellipse is 22/7 [Pi] times radius [1/2
length] of minor axis times radius [1/2 length] of major axis. Multiply by
depth for volume. Multiply by the necessary constant to obtain the volume
units of your choice!

Lets try this formula:
Pi times radius squared times depth = cu ft
cu ft x 7.48 = gallons
10 ft diameter 3 ft depth = 5x5x3.1416 =78.54 cu ft = 587.479 or
commonly expressed as 587 and one half gallons.
Smart people assume I know something and fail to explain in simple
terms, sometimes that just frustrates me.

Correct. My mistake.
3.14 * (1/2 diameter) * (1/2 diameter )*depth * 7.48 = gallons.

Oh, the 10 in Nick's was the depth, so
Pi (3.14) X radius squared X Depth X 7.48 = gallons
(Sorry guys, I prefer X for times over * stars, similar to most math books.
