Waterfall flow rates for waterfalls and streams your pump should pump at least 100 gallons per hour for every inch wide the waterfall is. For simplicity we ll stick to setups where the water feature is the only thing connected to the pump. Larger volumes need larger pumps. A simple calculation to know what the water volume of the fountain or pond is to calculate the length multiplied by the width and times the depth times 7 43 gallons per cubic foot or l x w x d x 7 43 gallons cubic foot.
