That’s maybe an argument against my point of natural water being applied to any water body surface, but as the wiki says: “<span style="-webkit-text-size-adjust: auto; caret-color: rgb(32, 33, 34); color: rgb(32, 33, 34); font-family: sans-serif; font-size: 23px; background-color: rgb(255, 255, 255);"> Used to tag an inland area of water.

Note that despite key name it is also used for artificial structures like moats, basins of a wastewater treatment plants, canals etc, including areas covered with water only intermittently.” so basically some artificial water areas are tagged with natural, and some aren’t.</span></div><div><br></div><div>Cheers Martin </div></body></html>
