Mac, Yes, in the morning they will open all the vales at Lock 7 and my section of canal will drain into the natural river section, leaving my boat and docks high & dry. They'll be shivering when the temp drops to 28 degrees below zero, but no ice damage. There will still be a small channel full of water about a hundred yards from the dock.
