🌉 Wait... Which Water?
WATER + UNDER + THE + BRIDGE
Is it about a river? Yes, as a picture. ✅
Do you need a bridge to use it? ❌
Stand on a bridge and watch a river. The water goes under you and keeps moving. You cannot bring the same water back.

🕵️ Where Did It Come From?
We are not certain. The Phrase Finder says the under the bridge form appears in a novel by Julia Kavanagh in 1858. That suggests it was already being spoken then.
An older relative, water over the dam, was written down in 1797. A French proverb from the 1840s says il passera bien de l'eau sous le pont, which means much water will pass under the bridge.
A dictionary says the idiom is from the late 1800s, which does not quite agree with the 1858 find. So the exact date is still a puzzle.
