Okay, I've sat back long enough and have not seen the post I need.  I
want to calculater the gallons in my pond.  Could someone please post
or e-mail me the formula for this rather basic calculation.  Thanks in
advace,

Length x width x depth (all in feet) x 7.48 = gallons US
Use the average if any dimension is variable.
For a rounde pond use 3.141 x radius x radius x depth x 7.48.  Again
the dimensions should be in feet.  4.5' not 4' 6" nor 54".
Good Ponding,
Fred

Our pond is kind of a wierd shape and lots of different levels in depth.
Someone suggested that we remove about a third of the water (we were
cleaning, anyway), then turn the hose on, see how long it takes to fill a
5-gallon bucket.  Then see how long it takes to fill the pond back up.
Multiply the time by 3, divide by 5 and we have about 700 gallons.  I know
it's not scientific, but we haven't had any trouble using that math for
the additives we've used.  (Not many, by the way, because we're trying
very hard to be ecologically kind).

Good ponding all.

How did your fish respond to the water change?  We have chloramines in
our city water and I worry about adding too much water at once.  Since
getting the pond established I don't worry about topping it off with
hose water, though.

How long has your pond been in?  I haven't come across much need for
additives yet although I did add some liquid bacteria after an ammonia
peak when I first set up the pond and added fish too soon - and lost a
few. {:-(  I've become a believer in the bacteria and used it when I set
up my barrel ponds as well.  I'm curious to see how the pond will do
after a winter.  Right now everything is very terrific out there.  There
are babies galore!  I'm thinking of adding a second pond to put my
fantails in so they will get a chance to breed once in a while!  I have
too many plants (believe it or not) and am hoping some of my friends
will want to set up a pond and take some off my hands!  I hate tossing
them in the compost!

(snip)

The formula for calculating the volume of a pond is...

Multiply the length x the width x the height (in inches). This will give you
the number of cubic inches. You then divide by 231 (the number of cubic
inches in a gallon of water). This will give you the number of gallons
contained in the pond.
 Ex.:  72 x 104 x 18=134,784 cubic inches
         Divide 134,784 by 231=583.5 gallons

John,

Unless your pond is a regular shape, and whose is, the only way to TRULY
get your pond volume is to turn the hose on, time the filling of a
measured container a few times to get an average time and then fill your
pond and time it.

Actually, you don't really need an exact measure for most things.  If it
is a roughly regular geometric shape, you can make an approximate
calculation the surface area, varies on the shape, and them multiply
that by the average depth.  Forget the slope of the sides unless it is
really shallow.  You now know how many cubic feet are in your pond.
There are 7.5 gallons in every cubic foot.  If you don't have your
geometry book, here are a few formulas to get the surface area:

Round:  Radius (half the diameter, remember) x radius x 3.14

Square/Retangle:  Length x Width

Oval:  1/2 of the width x 1/2 the length x 3.14

Capsule shape:  Treat like a rectangle with a circle.  The Rectangle in
the middle and 1/2 the circle on each end.
