Trapped Air Under Liner? Help!

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?

Three to five times PER YEAR? Yikes! You never want a pond built where the water drains towards it - but here you are.

You have a water hippo. You need drainage under the pond to get the water out before it builds up pressure. Could be as simple as a drain pipe to give the water somewhere to go or you may even need a sump pump under the liner. How a water drainage “pro” couldn’t figure that out would give me pause - find a new pro.

You also need to divert the water that is running under your pond. There is no need for that to happen in the first place if your pond has the proper drainage around it. And yes, you definitely need a new pro.
