(A range finder can be used to determine distance)
| Square or rectangular pond | = (length x width)/43,560 |
| Round pond | = (radius2 x 3.14)/43,560 |
| radius – is the distance from the shore to the center of a round pond | |
| radius2 – is the value of the radius multiplied times itself | |
| Triangular pond | = ((length of dam x total length of pond)/2)/43,560 |
Average Depth can be determined by making 4 transects per acre of water, recording depth measurements at three foot intervals along each transect and then averaging all the numbers.
