Quite scratchy... but can be fun!
This is the third and final class III. Just below Old Mill, the river turns hard right and lines up for this fun rapid. Scout on the rocks on river left. Be respectful, as you are in the backyard of various shops on Water St. in Williamstown. Run left/left of center working center into a fun, splashy hole. This rapid can be run again and again, walk up on river left.
