Enter the dimensions of your pond to calculate the total water volume in gallons.

Pond Water Volume Calculation Formula

The following formulas are used to calculate the water volume in different shapes of ponds.

Rectangular Pond: Volume (gallons) = Length (ft) * Width (ft) * Depth (ft) * 7.48052
Circular Pond: Volume (gallons) = π * (Radius (ft))^2 * Depth (ft) * 7.48052

Variables:

  • Volume is the total water volume in the pond (gallons)
  • Length, Width, Depth, and Diameter are the dimensions of the pond (feet)
  • Radius is half of the diameter of the pond (feet)

To calculate the water volume, multiply the dimensions according to the shape of your pond by the conversion factor 7.48052 to convert cubic feet to gallons.

What is Pond Water Volume Calculation?

Pond water volume calculation refers to determining the total amount of water a pond can hold. This involves measuring the dimensions of the pond and applying the appropriate formula based on the pond’s shape. Accurate volume calculation is essential for pond management, including determining the correct amount of chemicals, fish stocking levels, and filtration system requirements.
