The Three Gorges Dam causes the Earth to spin slower

The Chinese triple lake slows the Earth's rotation.

Three Gorges full of water is like stretching an ice skater with both hands out; due to the huge amount of water that accumulates in one place, the mass of the Earth moves away from the axis of rotation and thus the speed of rotation of the Earth slows down. The theory is so, but the actual number is not too large, because 42 billion tons of water is nothing for the amount of 5.972 billion tons of Earth.

NASA scientists calculate that the large amount of water in the Three Gorges lake will increase the day length to 0.00000000006 seconds.  If there are no other changes and continue to assume that the lake water will remain above the same level so that the day length continuously increases by 0.00000006 seconds, then in 47,650, the time of day will increase by 1 second.

The effect is too small for us to perceive, but at least mathematics gives us an answer on the extent of its influence.
