As we transition between seasons, you may notice, at some point, a slight drop in your pond water level, making you think you have a pond leak,

For many experienced pond owners, this can be a common occurrence. However, for a novice owner or someone who’s never experienced water loss before, this may be a caution for concern. Rest assured, no matter what end of the spectrum your expertise falls upon, there isn’t a need to panic, but there is a need to investigate.

Understanding the basic principles of identifying and fixing a pond leak will help you repair the problem quickly and efficiently.

Low Pond Edges

Settling at the pond’s edge is the one of the most common causes of a pond leak, especially if you own a new pond. Finding a low spot in the liner can be tough because the pond liner used in ponds and waterfalls is covered with stone, plants, rocks, gravel, etc.

What is the definition of a low edge?

 A low edge or “low spot” occurs in ponds where the ground settles in an area, typically not a large area, and pond liner is too low allowing a small amount of water to go out of the pond.

Usually, the low edges are found around the stream and waterfall where most of the settling may have occurred, especially after a few rainfalls. These areas are usually built up during the construction of the pond using the soil from the excavation and are the most subjected to settling.

So what’s your first move? 
The first line of defense is to carefully inspect the edges of not only your stream and waterfall, but also the perimeter of the pond. As the dirt around the stream or waterfall settles, it can create low spots that may cause water to escape over the edge of the liner.

What to look for? 
Keep your eyes peeled for wet mulch or gravel, or muddy areas around the perimeter of your pond – this is a dead giveaway that you have a leak.

If you do find a spot that’s leaking, all you have to do is lift the liner up and push some soil under it in order to raise the edge- Voila! Leak fixed!

Evaporating Pond Water

First, let’s have a look at what evaporation is and what it isn’t. Evaporation is defined as the process of turning from liquid into vapor. So is it possible that your pond water is simply disappearing into the air? Sure is!

The amount of water loss will vary according to the region of the country and the season. Ponds that are located in areas of the country with moderate temperatures and high humidity can expect to see 1 to 1 ½ inches of water loss per week during the spring and summer. Most of this evaporation should be replaced naturally by rain. However, if you live in an area with high temperatures and low humidity, it’s possible to see 3 inches or more of evaporation in a week.

Does your pond have a waterfall?
If yes, then you can factor in “splash evaporation” as a potential culprit.
The quantity and size of your waterfall(s) also affects the amount of water that is lost. Regardless of the climate, a 4’x 6’pond with a 20-foot stream and 5 feet of cascading waterfalls may lose as much as 2 inches or more every day!

What is Not Evaporation?

Evaporation is not filling up your pond all the way at night, and waking up the next morning to find the water lower by six inches. If that’s the case, you are now in leak territory. If your pond is experiencing a loss of water at a more rapid rate than normal evaporation, you most likely have a leak. But no worries, we are here to help you find it!

Obstructions in the Stream and Waterfalls 

If the above theories have been explored and it hasn’t resolved the problem, it’s time to check for obstructions in the stream and waterfalls. Rocks and excessive plant or algae growth inside the stream, or even in your biological filter, can restrict the flow of water and divert it over the edge of the liner.

Still Leaking? 

You’ve followed all the other steps and your pond is still showing signs of a leak?
It’s not time to panic, it’s just time to dig a little deeper! Not literally of course, you just need to do a little more investigating.

The first step, shut off your pump for a day so you can determine the approximate location of the leak.
Next, follow these simple step by step instructions to evaluate the cause of the leak:

a. Make sure the pond is filled to the appropriate level.
b. Unplug the pump.
c. Let the pond sit for 24 hours.
d. Let the water level drop, then you know the leak is in the pond.

When the Water Drops:
To source where the leak is occurring, allow the water level to continue to drop. Where the water level stops dropping is the level where the leak is located!

Concentrate your search around the perimeter of the pond at the level that the water has stopped dropping. At this point, you should probably consider calling in a professional, especially if you’re a newbie to pond ownership and maintenance. A professional can quickly locate and repair the leak in a timely manner. But if you’re an experienced pond owner and enjoy working on and in your garden, it’s certainly a project you can tackle with a little effort and time.
