Important Pond Calculations

To determine the size of a pond liner: 

LENGTH=(Depth x  2) + Length + 3 feet WIDTH=(Depth x 2) + Width + 3 feet

For example, to create a pond measuring 8  feet by 10 feet by 2.5 feet deep, you will need a liner measuring 16 by 18 feet.

Length=(2.5x2) +  10 +  3=18'                                   

Width=(2.5x2) + 8 +  3=16'

To calculate the volume of a pond:

Length x Width x  Depth x 7.48 = Pond Gallons

*  *  *  *  *

To calculate the size of a pump:

Pond Volume/2 = Pump Size

(The pump should circulate the pond's water volume at least once every two hours. Add to the pond's volume if you are using a fountain or waterfall. And remember, each foot up you are pumping reduces the flow significantly---so check the boxes to see what the actual flow is!)
