Splitting a single polygon feature into multiple features?

I have a polygon with a single feature that I want to split into multiple features.  The polygon represents land area that drains directly to the ocean rather than into to major streams/rivers, and I want to define which area to call individual features. How can I split up this feature into multiple features?  Is my only option to make a new polygon that overlays each area and then use clip? I thought ArcHydro could handle this, but now I just want to define which areas should be uniquely classified.

Any advice?  I feel like there must be a simple way to do this.

The attached image illustrates my question.  I want to make unique features for island areas and coastal drainage areas between major watersheds.

Thanks for your help!
