13' is max for me. 12' is ideal. The problem isn't the river per say but the numerous inlets and canals which feed it. They rise/back up and are hard to by pass on foot. They are seemingly every 500' feet or so with deep mud. Some do have fallen trees either partially or fully across them but unless your really stubborn(i.e. stupid) like me, you may not want to cross using them. One slip and your waist deep in sludge or worst face first in it
