The River System is closed this morning from Mud Lake to the Locks due to fog.
It wasn't necessary for us to turn on the scanner to learn this because about 4 AM, the boats started blowing their whistles a single blast repeated every 10 minutes or so.
Our house guests were awaken and wondered what was going on. We assured them it was just fog and would be lifting soon. However, it is 9:30 AM and I just heard a boat report that visibility is at 400 feet. So the fog is still very dense.
The calm wind with a high humidity is causing this river fog that doesn't seem to be anywhere else.
