River Description


Access through Dartmouth College land to the river is somewhat restricted. It is necessary to carry upstream from the take out unless special permission can be obtained. Carry up past the Dead Diamond tributary bridge and put in on the Swift Diamond as far up as you wish to hike. The Swift Diamond is mostly class III until the confluence with the Dead Diamond branch. At this point the river tumbles steeply through a narrow gorge with continous class IV water. Above 1000 cfs the gorge can be continous class IV-V with no let up till close to the takeout.

Protecting Access to New Hampshire Rivers

Northeast boaters can celebrate that another beloved whitewater gem has been protected. Paddlers on the Winnipeseaukee River are now assured that the put-in on the Lower Winni in Northfield, NH will be forever protected thanks to the donation of a parcel from Gloria Blais in memory of her husband Roger. Gloria donated the land to the Town of Northfield for the purpose of assuring that future generations of boaters will have access to the river. Protecting river access to the Winni is part of an ongoing effort by AW in the northeast region to protect river access.

Bellows Falls (VT) Flow Study Reveals Hidden Whitewater

A hardy group of northeast boaters climbed into the natural river channel below a hydropower dam to participate in a flow study designed to assess whether whitewater flows should be restored to this dewatered river reach on the Connecticut River. While significant obstacles remain, this site has the potential for providing instruction, playboating, and a big water feature that that could be run throughout much of the year and provide a much needed boost to the local economy.
