I just finished a hike from Hughes Gap to Highway 19-E over Roan Mountain. Here is a water report of the the sources that I personally observed between September 19-21.

Roan High Knob parking lot (Cloudland Hotel site): Restooms are open and the water fountain is on. Restrooms and water fountain will be shut off on 9/30 per the US Forest Service.

Roan High Knob Shelter: The piped spring is not flowing. Near the pipe is a clear pool of water where you could get a liter or two of water by dipping a few ounces at a time.

Carvers Gap spring: Pipe not flowing. Dry.

Piped spring just north of Grassy Ridge Trail intersection: Flowing. It took 45 seconds to fill a liter.

Stan Murray Shelter: Not flowing. Just drip, drip, drip.

Overmountain Shelter: Flowing well. It took 15 seconds to fill a liter. (People seem to be obeying the shelter closure but it wasn't raining.)

Piped spring before Bradley Gap: Not flowing. Just drip, drip, drip.

Doll Flats spring: Flowing. It took 2 minutes 15 seconds to fill a liter.
