I don't mind doing section II and section III however I have never been on section II myself.
Although I would only want to do it at 1.5+ feet because I did section III at 1.2 feet and it was nothing but scraping. I walked my boat through all of sandy springs, simply because it was the quickest way.
We shouldn't have to worry about the water level all that much with it being fall approaching winter.
Also don't really know about the trail systems just knew that the run beside a good bit of the river.
