Smith River: Route 104 to Old Route 104 Professional Review and Guide
"From its origin on Mount Cardigan, the Smith flows primarily eastward and empties into the Pemigewasset. It is a short, tricky run that can be repeated easily several times in a day. In character, it is typically New England —small and rocky. The section that is usually run is continuous whitewater for the most part. It is class III–IV depending on the level. Because of this, rescues can be difficult. The majority of the rapids offer many paths, although several have just one or two practical routes. Turns and maneuvers must be done with authority, lest the rocks gobble up your boat.
Eddies are not uncommon, but you must work to get in and stay there, usually crunching over several rocks in the process. A road parallels the river and, although it is no longer a major public thoroughfare, it can still be used for access. It is not plowed in the winter. Five miles downstream from this section, the Smith drops through scenic Profile Gorge, which ends in a picturesque waterfall."
