Ponds come in all shapes and sizes. Whatever its general layout, knowing the volume of your pond in "acre-feet" is important to help you determine the best way to maintain it. To figure the surface area of your pond in acres, follow these steps.
Next, you need to know the average depth of your pond in feet. Take measurements spaced uniformly over the entire pond. Add these together and divide by the number of measurements taken. This will give you the average pond depth in feet.
Finally, to determine the "acre-feet" of your pond, multiply the surface area in acres by the average depth in feet. The result equals the volume of your pond in "acre-feet." For example, if your pond is one surface acre with a 4-foot average depth, you would have 4 acre feet of water (1 x 4 = 4 "acre-feet").
To figure the surface area and acre-feet of your pond, follow either of these steps:
