# How deep should a large pond be?

## How deep should a large pond be?

Ideally a pond should be around 18in deep at the centre. Larger ponds can be 3ft deep but a greater depth than that is quite unnecessary. A foot and a half is deep enough to allow submerged aquatic plants such as water lilies to grow well and gives fish somewhere to hide.

### 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. If you want to grow marginal plants along the edge of the water, you need to create shelves for them to stand on.

How do you calculate water spread area?

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 big should a wildlife pond be?

In general, the larger the pond the more wildlife you can expect to attract. A depth of 20-60cm (8in-2ft) varied across the pond will suit the majority of pond flora and fauna. But don’t despair if you only have a small space: even a mini pond in a pot will provide a habitat and water source for garden wildlife.

## Is a pond better in sun or shade?

It’s generally advisable to build a pond in a sunny spot. You can, however, site a pond in an area that is in shade for part of the day, or sits in dappled shade. It’s not a good idea to put a pond in a very shady area, as it will become stagnant – the plants that supply oxygen to the water will need some sunlight.

### How many acre feet is my pond?

Square or Rectangular Ponds: Determine the acreage by multiplying average length (in feet) times average width (in feet) and dividing the result by 43,560. Example: A mostly rectangular ponds measures 350 feet long and 200 ft wide. To calculate acreage: 300 X 200 = 70,000 ÷ 43,560 = 1.6 acres.

What is the average depth of a pond?

For a typical bowl-shaped pond the average depth can be estimated as 0.4 times the maximum depth. So, a pond with a maximum depth of 12 feet would have an average depth of about 4.8 feet. A more accurate method for calculating average depth is to make many measurements and calculate an average.

How big of a liner do I need for my pond?

Add Safety Overlap of 1′ on each side of pond – or simply 2′ to each dimension. Your Water Garden Pond is going to be 17′ long by 12′ feet wide, with a maximum depth of 2′. Now add a “Safety Overlap” of 2′ to each of those dimensions. (21 + 2 = 23, and 16 + 2 = 18).

## How big of a filter do I need for my pond?

It might be too big for your pond. You need a filter that matches the size of your pump. The maximum flow rate of the filter must be equal to, or more than, the maximum flow rate of the pump e.g.

### How many gallons of water to fill a fish pond?

For our final example let’s imagine I want to know an estimate of how many US gallons of water it will take to fill an oval fish pond measuring 30 feet in width, 25 feet in length and 12 feet deep. The pond gallons calculator first figures out the surface area:

How big is an acre for a pond?

For a square pond, one acre is approximately 208 feet x 208 feet. It is important to note here that because of the increased size we are carrying our acre size calculations to three decimal points for more accurate results. Assume the pond is 80 feet by 140 feet and is an average of 6 feet deep.

How big is the bottom of a fish pond?

Imagine my fish pond measures 10 feet in length, 12 feet in width and the bottom of the fish pond is at a constant depth of 5 feet. I would enter these values into the pond calculator to work out the surface area:

Add Safety Overlap of 1′ on each side of pond – or simply 2′ to each dimension. Your Water Garden Pond is going to be 17′ long by 12′ feet wide, with a maximum depth of 2′. Now add a “Safety Overlap” of 2′ to each of those dimensions. (21 + 2 = 23, and 16 + 2 = 18).
