A  watermill is a mill driven by water power. It has a waterwheel or turbine which is used to drive a mechanical process such as milling, grinding, rolling, or hammering.

For hydroelectricity facilities, see power=generator + generator:source=hydro instead.

How to map

Add a node node at the centre of the watermill or draw an area area and add the tag man_made=watermill.

You can also add a name=*.

Tags used in combination

If a cafe is in the same building add another point and the corresponding properties. (See one feature, one OSM element.)
