Pond Maintenance: Knowing the Size of Your Pond

To properly maintain your pond you must first know the size of your pond.  After many discussions with customers it is apparent that many people do not know the size of their pond. Much of your pond maintenance product may be going to waste by not knowing the size of your pond. Not knowing the size of your pond will lead to wasted time, money and worse possible fish kill.

There are a couple easy ways to calculate the size of your pond.  The shape of your pond will determine which calculation method to use.

Square/ Rectangular (Gallons):

Multiply length x width x average water depth (feet) x 7.5

Example: 8' x 4' x 2' x 7.5' = 480 gallons

Square/Rectangular (Acres):

Multiply length x width, then divide by 43,560 (square feet per acre)

Example: 80' x 140' / 43,560 = .2571 which is approximately 1/4 surface acre

Round (Gallons):

Multiply diameter x itself x average water depth (feet) x 5.9.

Example: 4' x 4' x 2' x 5.9 = 188 gallons

Round (Acres):

Multiply circumference x itself and then divide by 547,390.

Example: 520' x 520' / 547,390 = .4939 which is approximately 1/2 surface acre

If numbers and mathematics aren’t your cup of tea…I have something that may make more sense.  Most visual people cringe when I ask, How many feet across is your pond?  So we have taken some fairly recognizable landmarks to help you visualize the size of your pond.  Ultimately you should do a measurement to get the most accurate size of your pond, but this will get you in the ball park (pun intended).

 

Also, keep in mind if visualizing and the calculations aren’t working for you, our team can measure your pond via satellite for a small fee.  Contact Sanco if you have additional questions or would like us to measure your pond.
