*Important Pond Calculations*

*To determine the size of a pond
liner:*

*Length + 2 x depth + 2 x
1½ ft (for overlaying outside edges under your coping of rocks.*

*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=(2½ ft x 2) + 10 ft + 3
ft =18'*ft

*Width=(2½ ft x 2) + 8 ft + 3 ft
=16 ft*

*We cut liner to fit your dimensions.
It is wise to dig your pond and then re-measure.*

*** * * * ***

*To calculate the volume of a pond:*

**Length x Width x Depth x 7.48 = Pond Gallons
(use measurements in feet) If you have a circular pond, multiply the
dimensions by 5.9 **

*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!) Also
the more fish you have, the greater the need for oygen.*
