Understanding Pond Calculations
Pond construction requires two primary calculations: determining the size of the liner material and calculating the total water volume for stocking fish, sizing filtration, and maintenance.
1. Required Liner Size
The liner calculation must account for the pond’s length and width plus enough material for the depth and overlap:
Liner Dimension = Pond Dimension + (2 × Depth) + (2 × Overlap)
2. Water Volume (Capacity)
The water volume (V) is calculated as:
V (ft³) = Length × Width × Depth
Gallons = V × 7.48052
Note on Irregular Shapes:
This calculator assumes a simple rectangular pond with vertical sides. For irregular shapes or sloped sides, add extra allowance for both liner size and water capacity.
