If there’s one water garden headache we get asked about time and time again, it’s pond leaks. Not only are they difficult to diagnose, but also difficult to find and fix. Luckily, we have a couple tricks up our sleeve to make this bothersome ordeal as simple as possible.
How To Find and Fix A Leaking Pond
Diagnosing The Pond Leak
To fix a leaking pond, you’ll first need to diagnose the cause behind your pond’s water loss. It’s quite common to assume a leak is what’s behind the water loss, but sometimes that’s not the case. It could be because of evaporation, overflow from low edges or because of excessive plants and algae growth. If none of these ailments are apparent, then it’s highly possible that you do in fact have a leak.

To properly diagnose and find a leak, you’ll need to turn off your pump for a day. Start by filling your pond to the appropriate level. Mark the water line. Now unplug the pump and let the pond sit for a full 24 hours. If water level drops, you’ll know it’s because of a leak. Let the water level continue to drop until it stops dropping. The level the water stops at is also the location of the leak.
Another little trick to find the leak is to use something already sitting in your fridge – milk. Pour some milk around the perimeter of the pond. If your pond is leaking quick enough, the milk will begin to leave a trace leading towards the leak.
Fix The Pond Leak
There’s more than one way for a pond to leak and more than one way to fix it. If you find the source of your leak to be caused by mechanical failure, such as a broken pipe or pumps, it may be time to call in the professionals. But if your leak is in the liner, there’s a couple quick methods to plug it up ASAP.
For a homemade solution, use cornmeal. Cornmeal was used in WWII as a quick fix to stop leaks in navy ship boilers. Use the same tactic by sprinkling cornmeal around your pond’s edges. The cornmeal will gravitate towards the leak, swell and bind with the soil underneath the water.
For a more concrete – yet still organic – fix, curate the hole with bentonite. Bentonite is a hydrous silicate of sodium composed of a clay with the ability to swell more than 20 times its original volume. Bentonite is inexpensive and can be found at your nearest agricultural supply store.
Finally, patch that leak up for good using a patch kit or underwater sealer. From vinyl to glass to ceramic, there’s a sealer and patch kit out there to fix any and all types of leaks.
