Working out the exact volume of water needed to fill a water garden pond may seem like an impossible task, but it is actually extremely straight forward once you know the right formula. This method will work for those building a new garden pond from scratch and for those installing filters and pond pumps in an existing pond.
Water garden ponds make a wonderful feature for every type of property. They add a touch of tranquillity to the landscape and are a perfect place to relax in peaceful solitude. Garden ponds also double as important habitats for local wildlife. Trying to determine the water volume of your pond is pretty much impossible without the correct formula. Knowing the exact volume of your pond is essential to enable you to decide what types of fish will thrive in the environment as well as the volume of chemicals to use for pond algae control. The following guidelines will help you calculate the volume of any type of water garden pond.
Measure the Pond and Record Findings
First of all, determine which shape your fish pond most closely resembles such as a circle, rectangle, or oval shape.
Measure the exact depth, length and width of your pool using a tape measure. Be sure to only measure the interior pool area of your pond. You can use the same formula to calculate the volume of existing ponds and those that are still under construction.
Calculate Volume for a Backyard Water Garden
For ponds that are square or rectangle shaped, use the formula: Length x width x depth x 7.5
This will give you an accurate measurement of the total capacity of your water garden pond.
For ponds or fountains that are in a circular shape, use the formula: Diameter x diameter x depth x 5.9
The diameter of the pond is the length from one side of the circle to the other through the middle point. Make sure you only measure the interior space. This will give you the exact volume of a circular pond.
For oval ponds, use the formula: Length x width x depth x 6.7
This will give you the exact number of gallons of water needed to fill your pond.
If your water garden pond is an odd shape, start by dividing it into the three basic shapes. You can then take individual measurements for each section and add them together to get the volume. For example, if your pond is shaped like a figure of eight, you can simply divide it into two separate circles.
Once you know the exact gallon capacity of your pond, you can then buy the correct pond liners, pond filters and proper size pumps. This equipment is essential to help maintain a healthy, balanced environment for the fish and plant life within your pond. A well maintained fish pond that is properly cared for with annual cleanings will provide you with a peaceful respite from the stress of daily life as well as increase the value of your property.
