Souhegan

As of January 2023, there is a giant tree/rootball embedded in the normal boat drop on far river right (the only smart way to boof these falls).  Scout this area easily during your car shuttle to see if the passage remains blocked by walking out onto the manual spill control adjustment pad.  Much of the tree is underwater and will be difficult to see from boat scouting or from the left side of the river. Portage is normally easy on far river left.  Maybe a large flow will dislodge the tree.
