Measure the average length of your pond and multiply it by the average
width and by the average depth and you will arrive with your total
cubic feet of water.
As there are 7.5 gallons per cubic foot, you can multiply your total cubic feet by 7.5 to get your total gallons in your pond. For example, a 4 foot by 6 foot pond 18" deep will be: 4 x 6 x 1.5 = 36 cubic feet. Then 36 x 7.5 = 270 gallons. |
