Calculate Your Pond Water Volume
For Rectangular Pond: Water Volume = length (feet) X width X average depth X 7.43 gallons/cu. foot = GALLONS
For an Oval Pond: Water Volume = 0.8 X ( length (feet) X width X average depth X 7.43 gallons/cu. foot) = GALLONS
For larger ponds & lakes: volume is expressed as "ACRE-FOOT" of water. This is the volume of water covering one surface acre at a depth of one foot.
To calculate, Lake Volume = surface area (in acres) X average depth X 326,000 gallons/acre-foot = GALLONS
