POND BUILDING TIPS:

Why Knowing a Pond’s Volume is Important For Selecting a Pond Pump

1) Gallons in a pond will tell you the following

a. Size of pump for you pond

b. Size of filter for you pond

c. Approximate Number of fish for your pond

2) How to calculate approximate number of gallons in an existing pond

a. Volume for rectangle ponds:

avg. WIDTH x avg. LENGTH x avg. DEPTH = Pond volume (cubic ft.)

EXAMPLE: 10ft x 12ft x 2ft = 240 (cubic ft.)

240 (cubic ft.) x 7.5 gal = 1800 Gallons

b. Volume for circular ponds:

RADIUS X RADIUS X 3.14 X DEPTH = POND VOLUME (cubic ft.)

c. Volume of a pond can be most accurately calculated by using a water meter that can be connected to a garden hose while initially filling pond.

HOW TO MEASURE FOR POND LINER

Take measurement of pond opening and use the following formula:

POND LENGTH:
Maximum Length + Twice Depth + 3' = Dimension #1

POND WIDTH:
Maximum Width + Twice Depth + 3' = Dimension #2

Example: For 8' x 10' opening that is 2' deep,
Length: 10' + 4' + 3' = 17'
Width: 8' + 4' + 3' = 15'

For this example, unroll 17' from a 15' wide roll of EPDM Pond Liner.

Pond Building Tip: Best to dig pond opening, take measurements and then secure the liner.
