If you are building your own water feature or want to know the gallons of water in your pond

here is some calculations to help you:

 

Approximate Gallons of Water in a POND

Length x Width x 80% x Avg. Depth x 7.48 = total gallons

***the basin takes up approximately 80% of the actual SQ. FT.

 

Approximate Gallons of Water in a STREAM

(Length x Width x .25 (Depth) x 7.48) = Gallons in the stream.

****You need 2x the amount of water in your basin****

 

Approximate Gallons of Water in a PONDLESS ® WATERFALL BASIN

With Stone

Length x Width x Depth x 2.2 = Gallons in the Basin

With Large Matrix

Length x Width x Depth / 4.3 = Number of matrix used

Number of matrix used x 32 = Gallons in the Basin

With Small Matrix

Length x Width x Depth / 2.3 = Number of matrix used

Number of matrix used x 17 = Gallons in the Basin

Rock Calculation for the POND

Length x Width ÷ 40 = Tons of boulders

***Using a 1:2:1 ratio***

For every (1 TON) of 6”-12” rock, Get (2 TON) of 12”-18” and (1 TON) of 18”-24”

Quantity of Boulders used in a STREAM

For Every 10’ of STREAM = (1 ½ TON) using 1:2:1 RATIO from above

Quantity of GRAVEL

Used in the POND Pond Gravel = 30% total tons of pond boulders

Quantity of GRAVEL Used in the STREAM

Stream Gravel = 30% total tons of STREAM Boulders

Small MicroPond/ D.I.Y. Rock Calculation for the POND

Length x Width ÷ 65 = Tons of boulders

Small MicroPond / D.I.Y. Quantity of Boulders used in a STREAM

For Every 10’ of STREAM = (½ TON) 6”-12” & (½ TON) 12”-18”
