I noticed this in the mcdonalds parking lot, so I poked around in it with a stick to try to clear the drainage path.
I came to the conclusion that it has no outlet at all, it’s a permanent stagnant pond. It stinks pretty bad.

FYI someone cleaned it eventually and there is a single 1” pvc embedded in the bottom to drain it to the adjacent ditch. A single leaf completely clogs it.
