Mike, how many gallons of water would it take to have one inch of water on one acre?

MIKE MOSS SAYS:      Charles,   It would take quite a few indeed! To get the volume of water involved, just multiply the area it falls over by the depth of the water. In this case, that's one inch deep times 6,272,640 square inches. That number of cubic inches equates to about 27,154 gallons. This calculation assumes that the one acre you specified is level ground.
