I'm casting my eyes over some property for sale off the road system, and see a lot of parcels that are on or near some very small streams. Looking at Google Earth imagery some of these creeks get less than 10' in width at times. I've yet to put a motor on a canoe and go upstream, so I have no sense of what the practical limitations are on taking a freighter canoe up skinny water. Does anyone have some experiences they can share on what to look for in a stream to ensure it's navigable? Or a trhead they can point me to?
