Any time we get significant rainfall here in GA my pond turns itself inside out and pushes most of the water out of the pond. It only happens when there is a lot of rain so maybe 3-5 times a year. So far it's happened twice in 2025, so I wonder if it is getting worse. It is very squishy and feels like trapped air under the liner. I am meeting with contractors to address drainage as it does run down hill and my entire back yard get wet. I met with one drainage pro today and he could not explain what was happening, but maybe water was somehow coming off the hill and getting behind the liner. Any one dealt with this before?
