Hard to tell by the photos but that whole section of lawn is just floating.

 

What happens if you poke a hole there? With a shovel?

How old is this lawn? Sod?

 

Lawn is 3 years old, started pouring again so I went out to take a look. My downspout trap was completely cover was grass, completely grown over. No water was making on top of the lawn, everything was being forced under. Once a ripped off the grass water shot up 12" above the lawn. Hope I didn't cause any lasting damage. I hate clay.

 

This is not a clay issue. Are the roots shallow?

 

Stab it with a shovel a few times and then push out the water. A lawn roller would probably work good if you have one

 

I'm going to roll it tomorrow, still way to soaked right now.

 

You can try aerating in the fall.

 

@greencare How will aeration help?

Poking holes is what he needs to do to pop the bubbles right now. Might as well do it to the entire lawn.

 

Pop the bubble, fix the drainage problem, and then tamp or roll the grass back where it belongs, it shouldn't cause any problems. Golf courses see this all the time, usually much bigger but it's not as issue if you can fix the cause, the grass will be fine.

Poking hole now will help, but you said aerate in the fall. How will fall aeration will help this problem?

In fall because you can reduce the stress on the lawn. You are opening up the soil with aerating, which will increase moisture loss in the summer.

This is your problem. Fix your downspout pop up/grate so it drains on top of the grass instead of under the grass.
