Use the result as a planning estimate and verify project-specific measurements, product information and site conditions where relevant.
How it works
The calculator finds the plan area of the selected shape and multiplies it by average depth.
volume = plan area × average depthWorked example
A rectangular pond 10 ft × 8 ft with a 2 ft average depth holds about 1,197 US gallons.
Assumptions
- Average depth represents the water column, not maximum excavation depth.
Limitations
- Natural and shelf-edged ponds are irregular; use measured average depth and treat the result as an estimate.
