Few things drive a pond owner crazier than water that keeps disappearing. Before you panic, though, know this: some water loss is completely normal. Evaporation is real, especially in summer, and a healthy pond can drop a bit in a hot, dry week without anything being wrong. The trick is telling normal evaporation from an actual leak. Here is how I sort it out.
First, Rule Out Evaporation
On a hot, windy stretch, losing an inch or so a week is not unusual, especially with a waterfall running. A true leak usually loses water faster than that, and it keeps going even when the weather turns mild. If you are topping off every couple of days, that is worth a closer look.
The Signs I Look For
- The level drops to one spot and stops. If the water falls and then holds at a certain line, that is a big clue. The leak is right around there, often in the stream or waterfall.
- You are adding water constantly. Topping off now and then is fine. Every day or two is not.
- Soggy ground or erosion at the edges. Water going where it should not often shows up as a wet spot, a little sinkhole, or washed-out soil near the pond.
- The waterfall or stream is the culprit. A surprising number of leaks are not in the pond at all. They are in the stream, at the spillway, or behind the rocks where the liner folds.
- The fish and plants seem stressed. A dropping level concentrates waste and swings the chemistry, which is hard on everything living in there.
A Simple Test You Can Try
Let the pump run and mark the water level. Then shut the pump off for a day and mark it again. If the pond holds steady with the pump off but drops with it on, your leak is in the plumbing, stream, or waterfall, not the pond itself. That one test narrows it down fast.
When to Call Me
Chasing a leak can eat a whole weekend and a lot of patience, because water almost never leaks where you think it does. Finding it is the job: I work the pond section by section, the liner, the plumbing, the skimmer, the waterfall, until I find where it is actually going, then fix it right so you are not topping off forever.
