Pond volume calculator
Estimated volume
Not calculatedgal
Use average depth across the shelf and deeper areas. Confirm water volume before dosing salt or medication.
Volume method
gallons = length (ft) × width (ft) × average depth (ft) × 7.48 × shape factor
shape factor = 1 rectangular · 0.785 circular or oval · 0.85 irregular
Measure length and width across the water at right angles. Average depth measurements taken across the pond, including shelves. The irregular shape factor is an approximation; a traced outline can account for the actual shape.
