Pond Volume Calculator
Estimate the volume of rectangular, round or irregular ponds.
How it works
Rectangular pond (L) = Length × Width × Average depth (m) × 1000. Round pond = π × r² × depth (m) × 1000. For irregular shapes, use average length and width.

Formula & Method
Rectangular pond (L) = Length × Width × Average depth (m) × 1000. Round pond = π × r² × depth (m) × 1000. For irregular shapes, use average length and width.
Example Calculation
A 3 m × 2 m pond averaging 0.6 m deep = 3 × 2 × 0.6 × 1000 = 3,600 L.
