Are all areas of the rivers classified the same way under designation?

There are three classifications under designation:

Wild river areas are those with the cleanest water, and the least amount of development around the shoreline.  These areas are typically only accessible by trail, and do not have impoundments.

Scenic river areas are those with clean water, and minimal development around the shoreline.  These areas may be accessible in areas by roads, and do not have impoundments.

Recreational river areas are those which may have some development along shorelines.  They are readily accessible by roads or railroads, and may have had historical impoundments or diversions.

Jeff asks -  

Can certain sections of the river, say an un-dammed tributary be designated "wild", while a different area that is dammed designated "scenic" or is it all of 1 designation or another?

Thanks for letting me know about your question.  The folks at the NPS confirmed my thought that different segments can be designated wild, scenic or recreational along the river, and that the whole area proposed for designation does not need to be just one of those categories.  So the answer to your questions is yes.

Thanks,
