how to figure out the gallons?

[-Asianguy-]

I'm basicly new. but i've been lurking on the pond forums.

I'm wondering how you guys come up with you gallon numbers (size) of your ponds?

i'm surfing google right now and there seems like 3 ways to do it.

 

[BIGgourami]

measure in feet, x 12 for inches
find volume in inches3
divide inches3 by 231 to get gallons

as long as you can measure correctly

Or 7.5 gallons/cu ft.
Or , for really irregular shapes : measure how long it takes your garden hose to exactly fill a 5 gal or other exact size container. Then measure how long it takes to fill the pond, and do the math.

 

[Muske]

Length X width X avg. depth X 7.5 gives a good estimate.
On irregular shapes break down the areas into small squares.

ony if you measure in feet

Drain it (if it has water in it) and then fill it with one gallon water bottles and count how many it takes to reach the top

We are bumping a thread the op hasnt posted on in 7 years to tell them to drain their pond into gallon jugs?

Even though it is an old thread, here are the best ways to calculate the volume of water in a pond: http://www.dallaskoikichi.org/calculating-volume-of-ponds/
