Last Sunday, as I drove back into town, I saw the rivers were running pretty full, so I parked by the bridge, got my camera, walked out and got this shot of the Confluence, where the North Fork (flowing under where I’m standing) and the South Fork of the Holston Rivers converge.  The diversion wall is overtopped (I’ve heard that part of that diversion wall is composed of concrete from the bridge that collapsed in the last century).  The diversion was necessary because the North Fork flows faster than the lazy old South Fork.  In times of deluges, the North Fork would prevent normal flow of the SF, which would back up and annoy the residents along the river.
