(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.
