Where Did My Water Go on Overfill

First time poster. Accidentally left hose on the other night. Water was only down about 1-2 hours worth of filling time. After 10 hours I went out to turn off the hose and to my surprise it was not overflowing.

I do not have an overflow valve and I couldn’t spot water anywhere in excess in my yard, around the pump etc.

so where did it all go?

Thank you for contacting Inyo. Do you have a small drain in one of your tiles? If so, you may have a pool discharge line that allows water to drain.
