How Much Water do I Have?

I get asked one question more than any other. How much water do I have? And you need to know this, at least approximately, so you can add dechlorinator, calculate how many fish you can have or how much to medicate them.


This is the formula for calculating the number of gallons of water in your pond. Because most ponds are irregular, the capacity will be + or - based on various contours within a rectangle or square (in gallons)

Rectangle: Length x width x depth = cubic feet.
One cubic foot of water is 7.5 gallons.


Circle: radius squared x 3.14 x 7.5
One cubic foot of water is still 7.5 gallons.

Remember.....you learned that in basic geometry
