Help with volume calculations of pond

[Shane77624]

How do I calculate the volume of an irregularly shaped pond?
Dimensions are as follows:
Top of slope measurements:
185X130X185X65

Bottom of Slope Measurements (Bottom of pond):
60x125x120x40

Depth:
14

All measurements are in feet.

Adjusted #, My calculator messed up.

This is what I used.

185 X 97.5 X 10 avg depth X 6.7= 1208512

to average ends (130+65)/2= 97.5
