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.

This tag is not used for  Hydroelectricity facilities, which are tagged with 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 the commonly used name with name=*.

Tags to use in combination

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