Pond Boss Forums POND CONSTRUCTION Renovating a Pond or Lake? Newly Renovated Pond Water Level

I agree with what Shorty said. But, with the cooler days ahead, the amount of evaporation should be getting less.

Suggestion:

Gt one of those plastic electric fence stakes, the kind that is relatively square with a metal spike on the end. Buy a 3' aluminum painted yardstick. At the same time, buy a rain gauge if you don't already have one. Attach the yardstick to the stake, and push it into the pond bottom. Write down the water level reading.

Keep tabs on the water level in the pond, and write down both the water level and any rain amounts you get. Compare that to the pan evaporation rates that NOAA, Cornell University, etc. have for the same time period for your area. If the pan evap rates are much less than what you are seeing in your pond for a number of months, then I'd begin to worry about not having a sealed pond. All ponds leak to some extent unless they have a rubber liner, but they shouldn't be leaking a LOT. At some point in time the pond bottom should reach saturation, and I don't think that will take more than a few months once the pond is at full pool
