Hey Jim! If you want to update the name of something, start up the editor, click on the item you want to change, and then fill in the Name field. The default iD editor has a good walkthrough that should help you with this.

One thing to watch out for with Scrabble Creek is that it's broken up into three parts, so you have to name each one of them individually.

Anyways, I've gone ahead and updated the name for you. If you open up the editor and click on the creek you should see the name now, although it may take a little bit for the rendered map to update.
