Finding reasonably detailed, current, map content like water areas can be a real challenge to map makers. Here's how you can find (and download) pretty high res, timely, land cover data, and convert it to vector polygons for your map. Plus a bunch of different ways to style water in ArcGIS Pro, if you are into that.
Here's the app where you can explore, and download, land cover data: https://livingatlas.arcgis.com/landco...
