Elliptical pond with shelf

Estimate an elliptical pond with a shallow shelf and deeper center.

How this works

Add outer elliptical area × shelf depth to center elliptical area × additional depth.

Example

Using the example inputs, pond water volume is 8,953.539063 L.

Outer length
6 m
Outer width
4 m
Shelf water depth
0.3 m
Deep center length
3 m
Deep center width
2 m
Additional center depth
0.7 m
Pond water volume
8,953.539063 L

Scope and assumptions

Ideal vertical shelf edges; irregular banks require measured volume. Not fish stocking or dosing guidance.
