South Branch of the Ashuelot River: Troy to Route 12 Professional Review and Guide
"The South Branch of the Ashuelot typifies a small New Hampshire stream. It is steeply pitched and rocky, it flows only in early to mid-spring, and when it is runnable, it is cold. The South Branch is a good complement to and is near both the main Ashuelot and Otter Brook. The South Branch is best run when the water is up.
In very high water, however, it is a river to be respected. The gradient is steep, especially in the upper portion of the run. At low water levels, rocks will annoy the boater who can paddle only in a straight line. In high water, rescues will be very difficult due to the powerful current. Route 12, which follows the river for the entire trip, is convenient for scouting and shuttle."
