Labeling using the River Placement style for polygon features

Some rivers are symbolized with a polygon feature due to their width. These rivers are special features that have many curves and tight bends that are not easily labeled without seeming cramped. The Maplex Label Engine's River Placement style generalizes the trend line for the turns of the polygon river and places the label following that smoother line. River labeling also allows the label to be placed following more than one bend.

There are two placement positions for polygon river features: Curved and Offset Curved.
