Sloshing water sound in back of my 2007 100 series!

I can hear water sloshing around in back somewhere when making turns in my 07 100. Any ideas where it is trapped? I did have a leak in the rear due to a glob of factory seam sealer and some gunk, but once cleaned that is ok. But this sloshing water is bothering me. Don't want to end up w rust. Thx for the help.

Pull your passenger's side trail light and look underneath. Rear AC evaporator drain plugged?

Thanks. I will try to do this tomorrow.
