millpond
Waterwheel power source
A millpond is a body of water dammed to provide power for a mill, typically small and calm.
The stillness makes it a standard comparison for tranquil water: The bay was smooth as a millpond.
The phrase like a millpond describes any unusually calm surface, especially the sea on a windless day.
