The formula for calculating the volume of the frustum of a pyramid is V = \frac{1}{3} h \left( A_1 + A_2 + \sqrt{A_1 A_2} \right) where h is the height of the frustum, A_1 is the base area of the top of the frustum, and A_2 is the base area of the bottom of the frustum.1 This formula can be used with bathymetric contours to approximate the volume of a water body.2 Applying the formula to the bathymetric map of West Hill Pond results in a calculated volume of 9.3 × 106 m3, or 2.5 billion gallons.

The background music is from the Open Goldberg Variations. Enjoy!

Fortunately, the worst of the storm never made it here. There was only a little rain and wind, but there was plenty of lightning.
