# POND CALCULATIONS

## Charts and Conversions:

**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

**Electrical Consumption / Conversions**

Amps x Volts ÷ 1,000 x (kw/per hour example: .10) x 24 hrs x 30.4 days = Monthly Cost

Watts = volts x amps

Amps = watts x volts

**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 1/2 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 = ( 1/2 TON) 6″-12″ & ( 1/2 TON) 12″-18″
