This video gives you a better appreciation of this beautiful place.  Since the watering trough has been removed, this is where I get my cool drink of Hundred Springs water now that the watering trough has been removed.  

There is much more flow from out of the ground outside of the pool than there was when I was a kid.  Coincidentally, there is another concrete enclosed pool about 30 feet to the right of this one.  While it was never great, that pool has almost no flow today.
