Acreage and Volume Calculations
Many lake and pond owners get confused when calculating
acreage and volume so we've made it easy.
If you are trying to figure out ACREAGE (of a square or
rectangle), multiply the Length (in feet) by Width (in feet) =
Square Footage. Then divide Square Footage by 43,560 (amount
of square feet in 1 acre) = Acreage.
Example: I have a rectangular pond that is 100'
long by 50' wide. 100' x 50' = 5,000 square feet. Then
5,000 / 43,560 = 0.11 acres
If you are trying to figure out ACREAGE (of a circle), multiply
the Length (in feet) by Width (in feet) = Square
Footage. Then multiply Square footage by 0.8 = Adjusted
Square Footage. Finally divide your Adjusted Square Footage
by 43,560 = Acreage (of circle).
Example: I have a circular pond that is 100' long
by 100' wide. 100' x 100' = 10,000 square feet. Then 10,000 x
0.8 = 8,000 adjusted square feet. Finally, 8,000 / 43,560 =
If you are trying to figure out ACRE-FEET, multiply the Acreage
by the Average Depth (in feet) = Acre-feet
Example: I have a 1.25 acre pond with a 6'
average depth. 1.25 x 6' = 7.5 acre-feet.
If you are trying to figure out GALLONS, multiply
acre-feet by 325,829 (gallons in 1 acre-foot) =
Example: I have 7.5 acre-feet of water. 7.5
x 325,829 = 2,443,717 gallons.
"We've been very pleased with your service and thought the
pond, under some really difficult circumstances, stayed clear and
weed free all year. We are happy with our healthy pond and
look forward to working with you next year."
