The Vermont Route 16 north of Glover to Lake Memphremagog stretch of the river is 21.5 miles (34.6 km) long and is rated by American Whitewater as a class I-III section. Glover is 20 miles (32 km) distant from Memphremagog.
Roaring Brook empties Parker Pond into the river in southern Barton near route 16.
The Willoughby River flows from Lake Willoughby into the Barton River in Orleans and provides considerable volume. Orleans was once called "Barton Landing" and was the place where, historically, craft could be safely loaded for transport north.
After leaving Orleans, it flows through eastern Irasburg, through Coventry and then into Lake Memphremagog.
