3. Pond Water in Litres.

What is pond math?

For example, a pond that is 200 feet long on one side, 300 feet long on the opposite side, and 100 feet wide would have an area = 250 feet X 100 feet = 25,000 ft2 or 0.57 acres.

### How do you calculate the slope of a pond?

Multiply for a 4 to 1 Slope Multiply the pond depth by 4 to find the total length the pond must extend to achieve a 4:1 slope. If the depth is only 1 foot, for example, the pond must extend 4 feet. A total length of 12 feet is needed if the pond is 3 feet deep.

## How do I calculate how many gallons of water are in my pond?

Calculate approximately how many gallons of water are in a pond. Average length x Average width x Average depth x 7.48 = Total gallons.

How do you calculate Litres of water in a pond?

If you pond is 2.5m long and 1.2m wide and about 40cm deep, you would then do the following using the formula (W x L x average depth x 1000) 1.2 x 2.5 x 0.4 x 1000 = 1200 litres.

### How do you calculate the average depth of a pond?

Average Depth: Determining average depth is most often calculated by dividing the maximum depth by two. This works if the pond bottom has a relatively uniform bottom slope. FORMULA: Maximum Depth (ft.) ÷ 2 = Average Depth (ft.)

How do I calculate the volume of a pond excavation?

So, the formula is: Ab = Wb * Lb, where Wb and Lb are the width and length of the bottom of the excavation. At = Wt * Lt, where Wt and Lt are the width and length of the top of the excavation.

## How many fish can be in a pond?

Some pond experts even go so far as to recommend only ½ inch of fish per 10 gallons of water as a maximum stocking density. If you’re a fish fanatic, you may find yourself with a pond containing 2 or even 3 inches of fish per 10 gallons of water and the fish seem to be fine.

What is a 4 to 1 slope?

For example, “slopes are expressed as ratios such as 4:1. This means that for every 4 units (feet or metres) of horizontal distance there is a 1 unit (foot or metre) vertical change either up or down.”

### How do you plant marginal plants in a pond?
