Blue Ribbon Trout Streams?

What is the story with trout streams that are designated "Blue Ribbon?" Some of these streams barely hold fish. I bet it would be helpful if the year of the "Blue Ribbon" designation was noted. Maybe such designations should be reviewed from time to time to ensure truth in labeling. Maybe a stream was labeled "Blue Ribbon" thirty years ago, but it deserves a skull and crossbones label in 2009.
