to calculate lIner lengtH:
l = max length + twice depth + 3’
to calculate lIner wIdtH:
w = max width + twice depth) + 3’
Volume for average pond:
wIdtH x lengtH x deptH = cubic Feet
cubic Feet x 7.5 = gallons
Volume for circular pond:
rad x rad x 3.14 x deptH = cubic Feet
cubic Feet x 7.5 = gallons
knowIng gallons Helps wItH:
• sizing pump • sizing Filter
• adding treatments • stocking Fish
components:
• underlayment, liner
• submersible pump
• skimmer
• waterfall Filter

pond length x pond width ÷ 65 = ________tons

tons of Boulders x .45 = ________tons

typIcal garden pond
If average depth is greater than 2’, consIder one oF tHe FollowIng:
• Bottom suction • Bottom drain • Vacuum Bottom drain
pond openIng: 10’ long, 8’ wide, 2’ deep:
calculate length: 10’ + 2(2’) + 3’ = 17’
calculate width: 8’ + 2(2’) + 3’ = 15’
allow approximately 1.5’ of overlap around
the pond’s perimeter. 3’ included in l & w.
perFect rectangle
ex: 11’ x 16’ x 2’ = 352 cu. Ft.
352 (cubic ft) x 7.5 gal = 2640 gallons
estimated gallons doesn’t take rock displacement
into consideration. a perfect rectangle
pond is estimated to have 2640 gallons, but
with gravel only has approx. 900 gallons.
most accurate method:
water meter (see page 7)
Boulders In stream
every 10’ = 3/4 ton
rocks In stream
every 10’ section = 1/2 ton
Because rocks vary in size, use these formulas as general guidelines.
• Surface of pond is constantly skimmed of floating debris
graVel allows For: colonization of bacteria, hiding man-made
items for a natural look, & allows you to place water plants

a good rule of thumb is to try to achieve
150 gallons per inch of width.
weIr wIdtH x 150 gpH = pump sIze*
ex: 36” weir x 150 gpH = 5400 gpH
Formula to determIne pump sIze
*consider vertical lift and tubing length.
• Basin matrix can replace up to 90% of
gravel that is traditionally placed in pond
free reservoirs
• they have up to 3 times more storage
capacity than gravel
• allows for smaller reservoir
• easier to maintain water levels

disappearing waterfalls and streams can be any size!
since there is no standing water at the base, maintenance
needs are minimal.
• Biological filtration is less important
• Mechanical filtration is less important
• algaecides may be added to keep water clear
• not required to run pump 24 hours a day
• Ball valves added to tubing to control stream flow
• Basin matrix allows for more water in reservoir
• water plants can be planted in gravel
