@makesittickhq: Canal lock water level: why the chamber stops filling exactly where it does. Water joined below the waterline runs from the higher surface to the lower, slows as the drop shrinks, then stops when both are level. The lock borrows its level from the canal next door. Even water knows when it's done.
