We are frequently asked for help in calculating the surface area and volume of ponds. Knowing these measurements is necessary information if you plan to add pond chemicals or dyes or even to properly aerate your water. Sometimes understanding the math to make the calculations can seem intimidating, but hopefully the following can help.
The most important part of any of these calculations is the underlying measurements. If the basic measurements are not accurate, the calculations will not provide good results. Use a tape measure rather than pacing it off if possible. You can also make length and width measurements using software available on the internet with considerable accuracy.
How to Find Surface Acreage: (All length and width measurements are made in feet)
How to Find the Average Depth of Your Pond:
How to Find Acre-feet (Volume):
For example: If your pond is 2 surface acres, with an average depth of 10 feet, your pond volume is 20 acre-feet of water.
If you are a math major, an engineer, or astrophysicist, you have my apologies. I know that there are ways to write all of these things as specific equations…But for those of you that hated algebra class, these directions are written to help you think of these as just a sequential process. If you are still baffled: don’t worry, give us a call… We are always happy to help you with the math and any other pond questions you may have!
