Water Under the Bridge Origin
Used since the late 1700’s or early 1800’s.
This idiom probably derived from the earlier, more complete, expression, “there’s been a lot of water under the bridge since…,” which was used to point out that a lot of time had passed and much had happened since one particular event had occurred. Both expressions refer to the fact that once water has passed by, it is gone forever and cannot be retrieved.
The variant water over the dam, which refers to water passing over a spillway as opposed to water flowing under a bridge, is a North American variant used since the late 1700’s. 3, 4
