You may delete one or multiple watch lists in the same action. However, you cannot delete a watch list that you did not create. For Bureau Chiefs, deleting watch lists that are designated as showcases automatically removes them from the Showcases portlet.
In order to delete a watch list that you are sharing, you must first
unshare
it. This action makes the watch list's Delete icon 
reappear. Now, you can delete the watch list.
To delete a watch list:
Click Manage
from the Navigation bar; then click Watch
List at left.
Result: The Watch List Management page
appears.
Perform ONE of the following:
Option
1 - For a single watch list: Click next to a watch list name.
Option 2 - For multiple watch lists: Select the check box(es) next to the desired watch lists; then click Delete.
When the deletion warning appears, click OK.
