Multiply the length times the width to get the square feet of surface area. This value can be converted to acres by dividing by 43,560 ft2/acre. So, a pond that measures 150 feet long and 100 feet wide would have an area = 150 feet X 100 feet = 15,000 ft2 or 0.34 acres.

How do I know what size my pond is?

Determining the size of your pond

  1. If your pond is rectangular to egg-shaped, multiply its length in feet by its width in feet, then divide that figure by 43,560.
  2. If your pond is circular, measure the total distance in feet around the shoreline edge, then multiply this number by itself and divide that figure by 547,390.

How do you measure a fishpond?

Calculating the volume of a pond requires you to first find the surface area, then the average depth. To measure the average depth, measure the depth of the pond in at least three areas, including the shallowest and deepest parts of the pond, add then together and then divide by the number of points you measured.

How do I work out the square meter of a pond?

View our Pond Filters Wizard here.
You will need to firstly work out the surface area of the pond by multiplying the radius by itself and then by Pi ( πr² ). The surface area is then multiplied by the pond depth to give the volume in m3.

How big is a 1000 gallon pond?

How big exactly is 1,000 gallons? Well, at three feet deep, a six foot by eight foot pond will yield 1077 gallons. But these are merely the minimum recommended requirements. Also, the more fish you have, the larger your pond should be.

How many acre-feet is my pond?

Finally, to determine the “acre-feet” of your pond, multiply the surface area in acres by the average depth in feet. The result equals the volume of your pond in “acre-feet.” For example, if your pond is one surface acre with a 4-foot average depth, you would have 4 acre feet of water (1 x 4 = 4 “acre-feet”).

How big is a pond?

A pond is a body of water less than 0.5 acres (150 square meters) in an area or less than 20 feet (6 meters) in depth. A lake is defined as a body of water bigger than 1 acre (4,000 m²), although size is not a reliable indicator of its water quality.

How do you measure cubic feet in a pond?

Multiply the length by the width by the depth to get the volume in cubic feet. For example, if your pond is 16 feet long, 8 feet wide and 4 feet deep, multiply 16 by 8 by 4 to get 512 cubic feet.

How deep should a pond be?

As a general rule of thumb, a pond should be 60cm (2ft) deep if you want plants and fish in it. Water that’s too shallow is vulnerable to evaporating in warm weather and freezing in winter.

How many cubic meters is a pond?

It’s a simple calculation you just multiply the average length x width x depth to calculate the cubic meters (M3). You then multiply this by 1000 to work out how many litres of water your pond system holds. In the below example we have an average length of 2m with an average width of 1.5m and an average depth of 1.2m.

How big is a one acre pond?

43,560 square feet

One acre is 43,560 square feet. Determining the acreage of a pond will be necessary to calculate the pond volume. Pond volume is measured in acre-feet of water. Not to get too far ahead of ourselves, but one acre-foot of water is one acre of water one foot deep.

What size is a half acre pond?

Calculate Pond Volume
A half-acre is 21,780 square feet. For a 2-feet deep pond, 1 foot of depth equals 1 cubic foot. That means the volume for the pond will be 2 times 21,780 square feet, or 43,560 cubic feet.

How do you measure a half acre pond?


  1. Step off or measure the length and the width of your pond in feet.
  2. Multiply the length number times the width number.
  3. Divide that total number by 43,560*. This gives you the surface acres of your pond or lake.

How deep should a 1/2 acre pond be?

8-10 feet

The main consideration when planning the depth of your fishing pond is what species of fish you plan on stocking. For warm water species like bass and panfish, an average depth of 8-10 feet is preferred in a ½ acre pond. Larger ponds can go deeper, of course.

How big is a 3000 gallon pond?

Savio PP3000 Complete Pond Package 3000 Gallons – Pond Dimensions- 16’ft x 21’ft x 2’ft. A truly impressive pond for larger backyards and commercial installations.

How do you calculate cubic yards in a pond?

Calculate Cubic Yards

  1. Calculate your area.
  2. Calculate your volume: Multiply area times the depth to get volume in cubic feet.
  3. Calculate your cubic yards: Divide cubic feet by 27 to convert to cubic yards and this is your answer.
  4. Where ft2 = square foot, ft3 = cubic foot, yd3 = cubic yard.

What are the dimensions of a 500 gallon pond?

He said the most popular size for a starter back-yard pond is about 5 feet wide, 10 feet long and 2 feet deep. Such a pond holds about 400 to 500 gallons of water.
